I have same as you and I am upgrading to the 17.5" wheels and Sailun S637 tires. I guess this is a good combo.

LT235/85R16 will work for 6000 lb axles which is what you have with that GVWR.

I replaced my previous 6lug axles on a Cedar Creek with Bridgestone Duravis R250 245x75R16, and they are built like a tank.

A 13xxx GVWR trailer probably has 5.2k or 6k axles.

I would look at the commercial grade all steel ply carcass Bridgestone R-250 in a LT235/85-16 E at 3042 lbs capacity = 12168 gross.
The XPS Ribs is another great option.

If the trailer has 7k axles I would go with the Sailun S637 commercial grade all steel ply carcass ST235/85-16 G at 4080 lbs capacity.
Or another all steel ply carcass tire in the Goodyear G614 LT235/85-16 G at 3750 lbs capacity. Both tires require a 110 psi rated wheel.

The first step in tire selection for your RV trailer was done by the trailer’s manufacturer. They are the only ones authorized to make that selection. According to government standards the vehicle manufacturer’s selection must be appropriate for that vehicle. Appropriate being able to support the trailer’s GAWR values on all axles. No one else has that authority. Sure, there are those that recommend lower load capacity tires for replacements but they have zero industry standards to support such recommendations.

Once the trailer has been sold a new set of standards is used for all subsequent replacements. It’s a simple rule and reads something like this, a quote from Michelin: “Never choose a tire that is smaller in size or has less load-carrying capacity than the tire that came with the vehicle. Tires should always be replaced with the same size designation — or approved options — as recommended by the vehicle or tire manufacturer.”

Certain people here want you to believe that the original ST tires put on were the best suited for the trailers design. The real truth is that those tires were simply the cheapest tire they could buy that met the requirements of the standards.

Cheapest equals the lowest quality they can find. Lowest quality leads to tires that barely support the load and expected use.

One of the above posters wants you to replace with the same or similar tire. All that will do is lead to continued problems. Try and PM him and see what he says. Odds are that he will not answer.

The advise of poster JIMNLIN is spot on. His experience is is extensive.

Someone who is spouting regulations and so called industry standard is not your best advise. Question where their allegiances are.

I have a max of 16500 on two 7k axles with all 4 drum brakes. I am going with high spec 17.5 aluminum wheels rated to 110psi and 17.5" Sailun S637 tires. You think this is the best choice?

Any LT will work just fine but the Bridgestone 250 or Michelin XPS steel rib tires are also rated for any position on a trailer and is noted in their advertising. If it says Tow Max, Rainier, or some other off brand and there is Made In China and ST molded in the sidewall, my suggestion is to look elsewhere for something more substantial.

You can also consider the Sailuns as they do (did?) have some 16" S637s too but you may need wheels that will support 110psig

So far we have ~15,000 miles over 2 years with our sig 5er on a set of low rolling resistance General Grabber LTs with zero problems and no significant wear.

Oh and I also agree with kedanie's description .

I think that is a great choice Fishalaska1.

Travelwrench, you might also consider Hercules H-901, or Kenda 12ply.

Ran me about 1750.00 for the 17.5 high spec wheels and the Sailuns shipped to my door. I hope I like them.

I installed 16" Bridgestone R250's immediately upon getting my trailer to the home campground.

The problem with the 17.5% G rated tires is that most fifth wheel trailers cannot handle a tire that tall. They don't have the clearance. It'd have to be a really big, heavy unit to allow such a tire.

You cannot believe how thick the tire sidewalls are on my Bridgestones. I think they weighed about 12 lbs. more each than the China Bombs that came on my trailer.

I was talking to the Costco tire dept. manager, and he's never seen a Duravis tire failure--and they're usually in extreme service F350's and F550's with service bodies and small cranes. And 16" LT/E tires are fine for the vast majority of fifth wheel trailers.

It is .5 inch difference in height from a 235/80R 16 to a 235/75R 17.5. Divide that by 2 since it is round and you have 1/4" taller needed for clearance.
