How Do Provider Tires Compare with Prometer Tires for a 5th Wheel Trailer

Question:

Thanks, so these tires are a little over kill for my trailer. But I want something that will stand up to heat in long trips. At 110 psi there good for over 4000lbs but will be hard and not much flex. Since I'm only going to have about 5000lbs on each axle, could I get away with 75-80 lbs of air so it's not so rough on RV?

I looked up Prometer tires because I have not heard of them before. Based on what I have found they are basically an economy brand. Provider tires on the other hand are a premium brand and what some RV and trailer manufacturers use in the production of RVs/trailers. I may be a little biased but based on what I know if it were my trailer I would run the Provider tires any day of the week over the Prometer.

Provider ST235/85R16 Radial Trailer Tire - Load Range G # TTWPRG235R16 is a great option. They are rated for 4,400 pounds at 110 psi with a 14 ply rating. I wouldn't say they would be too stiff since you are using them for a 5th wheel trailer and not an RV that you drive. You likely would not notice the difference between it and a lower load range with a lower ply rating.

The thing about trailer tires is that they should always be inflated to the maximum psi indicated on the tire. This is because trailer tires are built with a thicker sidewall compared to vehicle tires. If under inflated it can cause that thicker sidewall to generate excessive heat. If you want to run a lower pressure the capacity will be reduced, but I don't know by how much, but even within the lower capacity you could still have problems with heat build up. What I recommend is try it out at the maximum psi and see how it does. Then decrease the psi by only 5 psi at a time and be super careful about the amount of weight on the tires. There are other things you can add to the trailer to cushion the ride such as shocks. We have a couple of shock kits: # LC281281 is for 3 inch axle diameters and # LC281255 is for 2-3/8 inch axle diameters. One shock kit is recommend per axle.
