Hi All,Had our first experience using a TC last weekend with my wife and daughter (and our boat). Had a great time!I haven't decided which camper to get but am planning to do so in the spring, I have connected with a local guy who is renting us his TC when we want to use one. My current truck tires were not purchased with the idea of carrying a TC. I have BFG KO2's 35x12.5r18 that have a max cold psi of 65. The TC we used is very heavy but it was a good experience, a Lance 855s.These are going on my 2012 F250 CC SB 4x4 with a 6.7 diesel and I tow my 22' aluminum jet boat. I know this isn't the ideal truck for what I am wanting to do but it is what I own so I'm going to make it work. I understand the general concurrence is that a slide out camper should be on a swb dually, but that isn't going to happen. I've done a few upgrades to help carry a TC (I understand that none of these increase the vehicles rated capacity), Big Wig sway bar and airlift 5000 air bags, but with my boat in tow, some helper springs are needed too.Toyo's newer option for a f rated tire in my same tore size that can go to 80psi and is rated to almost 4000lb is tempting. I feel that the extra 15 psi and stronger sidewall would have made a big difference on the sidewall compression and roll caused by the tires. I will not be putting 19.5's on so this seems like the next best thing.Any one have experience with these?http://media.toyotires.com/press-releases?item=122476Thanks, Rob

I have Toyo's E rated tires 285/75/18's on my F350 and they are rated at 4080lbs @ 80psiCheck them out as they work great.Oh and not sure why you think a SWB Dually is the best answer? or did you mean for that camper? I run an AF990 on a long box F350 CC Diesel 4x4 and it does well.

I really loved my Toyo Open Country E rated on my old GMC Sierra 1500. Great, great tires. I added a 700lb leaf spring and Timbrens to that half ton and hauled an 8' Six-Pac camper with it. All in *fully* loaded wet weight about 2,500lbs. Here's the thing though... I never worried about the rear axle/GVWR etc. and the Sierra handled just fine I thought. What did happen after only 1 summer of camping though is all the brakes were completely shot and the rear bearings were also shot etc. So it was all the SUB systems that weren't handling the weight well at all. That costs money I didn't want to spend. Bye bye beloved Sierra.I now haul the same camper on a Ford F-350 dually one ton (1999, used, cheap, in great shape with the 7.3 so it doesn't have to be expensive & can be very reliable) and can honestly say I sleep much better at night knowing my family is likely much, much safer now. The dually doesn't even feel the 2,500lb camper and the better half is much happier being able to load as much extra stuff as she wants now without me always barking about weight..02 Best of luck. Gonna go read about F rate Toyos now and start saving some pennies. :-)

I recently had to make a tire decision also.The F range Toyo tires are the 35X12.50R18LT which have a capacity of 3970 lbs.Those are somewhat oversized and pretty tall tires.They don't seem to have any more capacity than the LT285/75R18 which are 4080 lbs.If you go down in sidewall ratio, at a LT285/65R18, it's still rated at 3640lbs E rating.I have the Nitto Terra Grappler G2s on my truck, in LT285/65R18 size, which have less sidewall flex. The LT285/75R18 Nitto's are Toyos performance line, and are rated at 4080 lbs. However, I didn't like the sidewall height.You get noticeably less sway with a 65% sidewall height ratio.

You still need figure out what your rim rating is. Heavier tires on weaker rims will not gain you any weight advantage but will give you a better loaded ride up to weakest component you have not upgraded.

That is correct, Bedlam.Ford forged aluminum wheels are 3590 lbs each for an SRW, as per Ford specs.

I've got Method Wheels in a 18x9. When I bought the truck and whatever I put on it up until 6 months ago had zero regard for a TC.

Since my wife and daughter loved it (my wife has given a TC the nod) I want to get my truck lined up to carry well.

If you have Method NVs, you may have one of the only light truck wheels actually rated very high. 4600lb iirc. Method only makes 1 or 2 styles with that rating. Most other wheels /brands are between 3000-3600 lb rating.
That said, OE wheels are typically very stout. Aftermarket can be as well. Lots of people run OE wheels with same weight as you, including me. And lots run it on aftermarket wheels too. See it daily. Your call there.
For the truck, before helped springs, look at wedging the overload lower leaf either with wedges or stable loads. Although the 2 F250s I had. 2012 and 2014? Models both had really soft rear springs compared to other HD pickups.

On what do you base that? (Not flaming, just asking)
...because as far as I have know, there are really no known specs of factory wheels as discussed here as nauseam...

I would tend to think that for legal reasons (if it ever push came to shove in a court) that truck mfgrs would take a position that wheels are only rated for as much as stock tire could handle (and no more.)
