Rickson wheel/tire advice

I was hoping to get some advice here on a set of Rickson wheels that have come up on craigslist. A set of 4 for $700.

I'm interested in getting them, but not sure what size tire to get. I have a 2006 Dodge 4x4 2500 diesel 4 door truck, short bed and Lance 855S camper. I plan to tow a larger trailer than the little kayak trailer I usually tow, which is why I'm looking into upsizing the tire/rim capacity.

Rickson site says I can run 245 up to 285/70R19.50

Also, my Dodge stock offset is 1.41" and these rims I'm looking at on craigslist are 1.125". Personally, I don't see how a quarter inch is going to matter. Certainly within the range of fitting inside my wheel wells, but if anyone has any cautions or concerns I should be aware of on that issue too, please let me know.

Thanks

****EDIT****

Currently running Nitto Terra Grappler AT size
LT285/70R17 E 126R

They are listed as 32.76 diameter and 11.5" overall width. Load rated at 3750 pounds each.

That weight is without a trailer. Just my truck and camper.

I tow a small single jet ski trailer with a kayak instead of a jet ski on it. I also tow a 2-rail dirt bike trailer with one dirt bike on it at times. Neither one weighs more than 50 pounds tongue weight or 500 pounds total weight.
Eventually I want to flat-tow a Suzuki Samurai or some such.

Let's see if I can figure out why it's so heavy. In the camper is a label with the weight of my particular camper with it's accessories as it left the factory. That label states the camper weighs 3190 lbs with a full tank of water and propane tanks full. It also says options that weigh less than 8 pounds were not tallied and could add up to as much as another 150 pounds. So, call the camper 3300 pounds from the factory.

I've added a bunch of stuff to my truck;
Hellwig Big Wig sway bar 50 pounds
Hellwig LP-35 Heavy duty leaf kit 75 pounds
Hellwig LP-35 Mounting hardware kit 25 pounds
Torklift front and rear frame camper tie downs 20 pounds
Torklift Superhitch 50 pounds
Torklift 36" Supertruss 50 pounds
Air bags 35 pounds
Rickson 19.5" wheels 250 pounds
Toyo 19.5" tires 330 pounds
Front receiver hitch 50 pounds
Front push bar/driving lights 50 pounds
running boards 80 pounds
That totals 1065 pounds. But need to subtract the stock wheels and tires. I'd have to guess those at 80 pounds each, based on how heavy my spare, which is stock feels. So, call it 750 pounds of truck mods.



Camper..................3300 pounds
Truck Accessories.. 750 pounds
Me and DW............ 400 pounds (with cab stuff; water/treats/GPS, phones, etc..
Camper loaded gear. 250 pounds
Batteries................ 150 pounds (sticker in camper did not include batteries)
------------------------
Subtotal.................4800 pounds

If this is accurate, then my truck weighs about 7360 pounds. I bet this is very close. Checking around on the web forums for Dodge diesel trucks, my year, they all over 7,000 pounds minimum and 7600 pounds with driver on the scale.

For anyone wanting to guess their outfitted camper weight, a good rule of thumb is what ever the manufacturer said it weighed at delivery PLUS 1000 pounds. I'm right there. (Minus me and DW. Just the camper ready to go)

That shimmy at a particular speed is a balancing issue. Can you swap tires front to rear and see if it changes?

I found less rolling resistance with my 19.5's rated at 4805 lbs, but I had 100 psi verses 80 psi in my 18's.

I see you are over 12K lbs GVWR - My F250 with AF811 would only be that heavy if I was towing. How heavy is your trailer and how much tongue weight will that add?

A couple observations from my test drive to Tahoe yesterday. I have the 6 speed manual transmission.

1. The motor turns at 1750rpm's at 60mph. That's down from 1900 rpms from the factory stock tires.

2. There seems to be slightly more rolling resistance. I have a 'test hill' that I can coast down that is 5 miles long. A perfect grade with a few hills that I can coast over at specific speeds if I start the coast at a specific speed. In this case, if I start the coast at 55mph, I will top out at 70mph and slow down to 45mph on the humps along the coast. Now, knowing that my speedometer will be off by almost 10%, I use my GPS to measure my actual speed. I was off a couple mph with the new tires. This may not be due to rolling resistance though. It might be due to air drag as I now sit higher and there's got to be more air turbulence under the truck because of it.

3. The shimmy I can still feel through the shifter is at it's worst right at 60mph. I also noticed that it more pronounced while on curves and just about non-existent on straight sections.

4. Te shimmy is not affected by coasting or under power. Same shimmy. So definitely tire/wheel related.

5. The steering tends to pull to the right. However, I've got to spend more time on testing this. I actually think that the steering is affected more by the crown of the road, which usually falls from the center to the shoulder. It's hard to find truly flat road that is also straight and long enough to let go of the wheel and see if there is a pull or not. Especially if there is any cross wind. Anyway, it's more than it was with the Nittos on there. With those, I could let go of the wheel for an extended length of time and the truck would stay going straight.

6. My wife notices the extra height as she gets out of the truck. You wouldn't think an inch or so would matter, but she darn near fell out yesterday and said it's a higher step out now.

7. Driving up grades doesn't feel like I need to push on the pedal any more or less than I used to with the smaller diameter tires. Sometimes, gearing up with a tire size change can cause a loss of power because of the rpm range in use. I sure couldn't tell. I've never been able to 'max out' my truck on grades, meaning, I've never had a grade where, in top gear, I was loosing ground speed with the pedal floored and would need to downshift. If I hit a grade at 55+ I am able to accelerate by using more pedal, or maintain speed without having to floor it. (Hope that makes sense) Some grades are over 7%. I like this because if the road is capable of 55mph or faster, I can leave the truck in 6th gear and not have to down shift. Below 55 I MIGHT have to downshift, depending on how steep the hill is.

These are the Toyo M608Z 265/70R19.5 and have a max load rating of over 5500 pounds per tire. I chose them over the 245/70R19.5 because they were "only" rated to 4500 pounds per tire. My rational is that I don't have to inflate these to 100+ pounds to do what I need; carry my fat truck's weight safely. I only need to inflate them to 82psi to get the same load rating as the 245's at 100psi. Makes for a more comfortable and quiet ride, plus the tires will last a lot longer.

I also have a Subaru Forester when headed into snow country and not needing to take a camper.

Buzz; yup! I just couldn't ignore both my load and tire ratings after I blew it and weighed my truck last year. Ha! Also, I couldn't ignore what happened to you since we live in the same general area and drive the same highways.


It's taken me almost two years since that blow out at speed and numerous truck and tire upgrades but I am finally back to just driving, relaxing and driving, instead of being hypersensitive to every bump, wiggle and thunk. Amazing what having the proper tires and wheels for your load will do to help with "just chilling on down the road".

My advice to everyone is stop with the "I think its fine" bull******guess and get your rig to the cat scale and really know if it's fine or not.

They look good. Do you ever chain up? I was concerned about clearance and did not go larger than 245's because of that. With stock Ford height, my 245's would clear chains on the front and rear.

I got my tires today and long story short;

I like them!

I feel much more confident
No tire sidewall roll on turns and bends
Ride height increased by 1"
Feels good at speed.

I got a call this morning from Robbie at Les Schwab. Yes, we are on first name bases. His folks live near me turns out. So I headed down there and Robbie rolls out one of the 265's and we compare it to the ones I have on there now; the 285/70R17's. A little taller, a little narrower an whole lot more agressive tread. So I told him 'DO IT!' and get gets started. First thing we discover is that the first mounting is needing 10 ounces of weight to get right. So Robbie takes the tire off and spins the wheel on the balance machine and it's the wheel, not the tire. At 60mph spin, it's pretty obvious that the wheel is not all that true. Not left/right wobble, more egg shape/oval. He checks the other three and they are all the same. We were thinking I bought these used from someone who knew one was tweaked. But all 4 were the same, within an ounce. No sign of any damage. I am a little bit perturbed that Rickson ships out wheels that much out of true. No wonder Rickson promotes that they mount and balance. That way no other tire shop will bad mouth them. Ah well, it is what it is, so I give the go ahead to Robbie to proceed. Next comes the air pressure. Using a chart provided by Rickson and produced by Michelin, we find the air/weight table that pertains to my tire/wheel combo.
You can view the charts here;
http://www.ricksontruckwheels.com/load-charts.php
To read a chart, find your tire size specific chart. Mine is the 265/70R19.5 LRG. There are two charts with that designation. To find which chart is for my tires, look to the right side of the chart and find which one is for tires rated at 5510 pounds for single wheel. Now just read the top for tire pressure and down for load capacity (S for single D for dually)
Robbie recommended that we set the air at 85psi which equates to 8970 lbs for the rear axle and 70 psi which equates to 7680 for the front axle. Sounds good to me and is in line with what Rickson staff told me when I called them asking questions. Rickson staff told me to not run at max pressure. They said that the tires will wear faster if they are grossly over inflated compared to the load. I'd have to agree. On the way home empty of camper, I could see the contact area was about half the width of the tread of the tire.

With tires mounted, balanced, aired up and now installed on the truck, time to have a look and see how they sit. They look nice. They fill the wheel well without looking too tall, too short or too skinny.

Now to see how they drive. Both Robbie and Rickson staff told me to expect wiggle on the feel until the tires are broken in. I was told to cycle the tires by running them for a couple hundred miles, let set 24 to 48 hours, then repeat. The heating/cooling of the rubber compound changes the hardness of the rubber compound and the tires will soon quit 'squirming' on the lugs as they flex. I already know what that feels like with the Nitto's that I had on previously. That went away after about 2,000 miles. Up to then, it felt like I was steering a boat that wasn't up on plane. The rear end seemed to react slightly lagging the front end when turning sharp or swinging the steering wheel back and forth a few times quick.

Anyways, I take off an drive it. On surface streets, it's as identical to the Nitto's these just replaced. Get on the freeway at right at 60mph I get a shimmy through the gear shift lever. Slow down, speed up; it's right at 60. So I take her up to 70. Shimmy goes away. Slow down again and shimmy comes back about 60. By 58mph, it's gone. Nothing big and later when DW is riding along, she doesn't feel it. Just me through the shift lever.

Off to home I go to take some measurements and load up the camper. First, I test my torque wrench to LS's. They set the lug nut torque to 145 pounds. My wrench reads 150. Close enough and now I know when mine reads 150, it's 145 on a calibrated torque wrench. I asked Robbie and he confirmed they have their wrenches calibrated on a regular schedule.

I stopped off and filled up the truck with fuel as I'm going to a scale later today. Static height with no load in the truck and the tires are just a hair over an inch taller than the Nitto's were.

Camper on and the Toyo's are 1.2" taller than the Nittos were. All loaded up and off we go! The ride loaded with a full camper and a full fuel tank is much more stable. No wallowing, sidewall flexing feel at all. Almost like it's empty except that the ride is a bit softer and the 60mph shimmy is almost all the way gone! I went through 60mph a few times, waiting to hear DW mention it, as it was her 'job' to tell me what feels different; good or bad. I finally mention the shimmy feel at 60, even though it's reduced from when the truck was empty, and she says maybe she feels it, but that it could just be the road. I ask her if she thinks the tires are louder. She said, not really, just different. We were able to use our same voice, radio at same setting, etc. I could not hear ANY difference in tire noise.
Now on the freeway, it's much easier and relaxing to hit 65. It feels like 55 or 60 did before the new tires. I can feel the side wind a little more at that speed though.

We headed back to Les Schwab as I want to show Robbie my camper. When I pull in, 3 of the other tire techs come over and they all want to look in the camper. Robbie comes out and asks if I can wait for his girlfriend to come over. He has the same 3rd gen Dodge truck as I do, a 2001 and mine is a 2006, and he's so impressed with the look that he wants to show her. She comes by and I give them to tour. Robbie tells me that if I ever want to sell my truck, he'll give me what I paid for it new. Same with the camper. The other guys couldn't get over how much room is in a short bed camper. They recall putting my take-off Nittos in the bed and they had to be leaned up to all fit and get the tail gate shut. Now there were 4 of us, all full sized men, in the camper and we are not crowded.
I told Robbie of the shimmy and he said to give it a couple thousand miles and come back to see him. He'll make balancing adjustments at that time.

We left the lot and headed up to Lake Tahoe, a climb of over 5,000 feet of elevation to a bit over 7,200' and have dinner while watching the sun set over the Lake at an outside table. Then we head home. The truck is much more stable feeling. I can now see why people are willing to drive off pavement. It's very sure footed now with these tires and wheels.

On the way up to Lake Tahoe, I stop at a weigh scale that is closed. The scale is turned on though and it's the type that weighs one axle at a time. My rear axle weighs 7540 pounds rear and 4620 pounds front. Total 12,160 pounds. (That probably just sent the weight police to the emergency room with a heart attack)

A couple of things; I was able to calibrate my air gauges and my torque wrench since Robbie set my air at 85psi rear and 70psi front and torque at 145 foot pounds.

Also, Robbie saved me an additional $33 because my wheels came with excellent valve stems and he didn't need to install new ones.

The tires, mounted, balanced and installed on the truck, with the LS warranty totaled $1799.93

Tires were $379.82 each
FET was $14.84 each
Wheel balance was $22 each
Sales tax was $126.29
Tire tax was $7

As you may recall, Costco was going to get me a set of the 245/70R19.5's for $1675 out the door, but I would have to mount and balance them someplace else and no warranty other than from the manufacturer.

I think I did the smart thing going through Les Schwab. The Placerville store has the nicest crew. Everyone was interested in my truck and what I was doing with it. They all cared. That's saying something in today's retail establishment. Many times it seems like I deal with a younger generation who treat customers as if they are doing them a favor or that they are a big bother. The crew at LS, from the first phone call to the final goodbye after coming back to show them the camper on the truck, showed that they liked their jobs and that they liked their customers.

The concern should not be whether or not Centramatics work with any particular size or brand of tire. The concern should be whether or not Centramatics work with the shape/offset of your wheels.

For example, I found that Centrametics did NOT work with my 3/4 ton Suburban with stock PYO 16" wheels. So for that application, I ordered a set of Balance Masters, which are dynamic balancing discs following the same principle as Centramatics, but instead use mercury instead of shot bbs suspended in oil.

So I have Centramatics on one tow vehicle, and Balance Masters on another.


I ordered and received a set of centramatics for my truck. After speaking with Les Schwab, I found out they will not put them on when I buy my new tires, but they will leave them if already installed. So this evening I took a front tire/wheel off to try out.

Long story short; they don't fit. The instructions say the Dodge might need an included spacer to allow clearance to the caliper and sure enough it did. However, when I put the centramatic on the inside of the wheel, it was obvious that they hit the wheel on their circumference before seating on the center where the holes are. Well, it flexes I figure and continue to mount up the wheel sans tire. It flexes alright. Right into the caliper I just installed a space to clear. So these won't work with Rickson wheels on the front. There may be another centramatic that will, however, I noticed that these things show up very well in the wheel holes and it just doesn't look good or right. I didn't try the rears as I want a set of 4.

So back they go soon as I call Hitchsource tomorrow where I bought them for an RMA authorization.

I'm hoping the tires came in today at L.S. and I'll be able to get them installed and testing beginning tomorrow.


One more thing; tire diameter.
I've been figuring on 1" total larger diameter running the 265's but that was comparing them to the 245's. I didn't think to compare them to the tires I have on there now; Nitto Terra Grappler 285/70R17. The Nittos are 32.8" tall mounted and loaded on an empty truck. The 265/70R19.5's are listed at 34.4". That's a difference of 1.6". Just wanted to make sure I got that documented here.

That's important information for anyone following this thread; just exactly where are you planning on driving your TC? I prefer to use my TC as a staging camp, then heading out with either my trail motorcycle, or, in the future, with a towed Suzuki Samurai or some such vehicle.

You do most of your driving off pavement and that's a whole new perspective when looking at putting together a package that will do this safely.

I want a TC to cruise to Idaho, say, and you want a TC to cruise THROUGH Idaho. Ha!!

Skipro3, thanks for your detailed explanation. Having this information will help inform and maybe create a realization that more factors are changed with every improvement. Especially when tire sizes are changed from the original design parameters for your truck. My experience will be very different than most, as I am more in the terms of a battleship, with the majority % of my weight is below the wings of my Truck Camper. Your set up will be more familiar with most TC users. Like you, the main emphasis was increasing my safety margins. While I was below my weight requirements for my 225, but not much. The biggest issue for me is that the majority of my driving is off pavement roads and with the sidewall deflection I was more concerned with carrying weight for these road conditions and possible cutting of sidewalls by road and debris material.

Look forward to your further testing and long term experience, as this upgrade is something many here might possibly consider for future improvements to their TC and family’s safety.

Cord? Cord, tire cord? Uhh, never mind. :B
