235/80/16 tires what let tires did you go with

[rtaylor0830]

I am thinking of switching to a lt tire from the st 235/80/16 I have now. My question is I have had blow outs with the st tires will the lt do the same and how is the ride( bumpy etc)

[GACamper]

We went with the Goodyear G614 and have been very pleased with them.:B Should have done this before the blow out happen :S
You need to make sure your rims will handle 110 psi. It will be stamped in the back side of the rim.

Capacity: 3,750 LBS @ 110 PSI
Ply Rating: 14
Service Description: 126/123 L

I run Maaxis tires on both RVs in 16". Both RVs came with 15" tires so the upgrade to 16" was a no brainer to get farther away from loading the tires to max rating. If they had had 16" wheels I would have went to the 17.5 tires for the same reason.

11300 minus 2200 lb pin weight = around 9100 lbs on the tires or 2275 per tires minimum.
Now add a nice 15 percent reserve capacity and your looking at a tire with around 2600 lbs capacity.

I use LT215/85-16 E tires at 2680 lbs capacity at 30.4" diameter on my 11200 lb 5er with 5200 lb axles. I prefer a 85 series (narrow) tire on a trailer if at all possible.

For a 11300 lb trailer you sure don't need a load G tire at 3750 lb capacity. Their tops for a trailers with 7k axles or maxed out 6k axle

Commerce runs on fabric carcass tires such as a Firestone Transforce HT or the Cooper HT-3 or the BFG Commercial 2 T/A or the Goodyear Wrangler HT. I've ran these brand tires on my various heavy GN road trailers

And as was suggested at the top of the 16" LT E tire chain are the two commercial grade all steel ply carcass Michelin XPS RIbs or the Bridgestone R-250. These two tire are just about bullet proof in a trailer position with their steel ply carcass.

Sorry didn't see the fifth wheel part.

Just put my second set of Firestone Transforce LT 235/85 16 HT on my Big Country,10250 lbs empty. First set I had for 4 yrs and put 14k on them, and still looked great. Sold them to my brother for one of his work trucks. Most of my travels are from the West Coast of CA to MT WY and ND and next week going the Northern route through Canada.

We don't have braking or traction issues on wet or dry roads with 215/85 series tires. They have a 6.5 to 6.8 tread width which works great on tires with close spaced axles in the center of a tall heavy box.
The 235/85 has 3042 lbs capacity vs 2680 lbs for the 215/85 which work out fine for 5.2 lb axles and smaller.

The LT215/85-16 E came OEM on one ton DRW trucks for years till axle capacities went up.

I would not go as narrow as a 215, stick to the normal 234 width, better traction footprint for braking.

Are you aware that the 17.5" Goodyear G114 and Michelin XTA tires rated 4805 lbs @ 120/125 PSIG such as are used under our 19,000 lb GVWR DRV Mobile Suites are 215 section tires? 215/75R17.5

Sailun S637 here too.

[mudmaker]

Just mounted up four new Sailun S637 tires this morning on my camper. Went back to an st tire with these as my Yokohama LT tires were almost four years old. No sense in chancing it. I was impressed with the weight and my friend who drives otr for a living says they are a good buy. Everything I have researched says the same.

Chances are, your rig is placarded for only D-range tires. My Komfort, with 11,300 GVW, is. I upgraded to E tires and have not had any issues. Doesn't mean that my 2nd set of tires still didn't separate, but that was really beyond the "normal" lifespan, so I can't complain too badly. The OEM D tires all separated within 2 years and < 2,000 miles. I =am= running 15" wheels, so have much less to choose from than you do, with 16" wheels.

If you are tired of blow outs, put Michelin XPS Ribs or Bridgestore Duravis R250's on it. For the LT235/85R16's you need 33" or more center to center on the axles. The LT245/75R16 is about the same diameter as your current tires, however they are a little wider. Chris

Goodyear makes a all steel tire for trailers that is 14 ply rating, and good for some 3,750 pounds. But most dealers will not mount it on a light trailer, even if the rims will only see a max of 2,800 pounds, unless the rims are rated above 3,700 pounds.

Most tires have polyester sidewall, and that can allow a lot of flex, and 'wiggle' in the rear axle. The all steel tire has a much firmer sidewall, thus less wiggle in the trailer when towing, it is especially noticeable when going down a hill and into curves.

I wish that RicksonTrucks.com would make a 17.5" rim for the 10 lug application of my class A motorhome. They make a dually application for the class C, but my front axle is rated at 6,000 pounds and the total tire capacity is only 6,084 pounds. So at some point going into a curve, one tire or the other will be overloaded, as the motorhome leans a bit.

Was your tire blowout in the same position? Such as right side - it can happen if you pick up a nail in the passenger side tires, and do not notice the slow leak, until the tire has blown out.

Good luck!

Fred.

If you switch to LT tires you will likely not have the problem with blowouts that you have with ST tires. That's assuming that you buy good LT tires that can handle the load, and you maintain them well.
