What are the Tire Pressure Ratings for ST235/85-16 Trailer Tires?


I have a 32-foot camper weighing 8200 lbs. The tires say put 90 psi cold. Is that correct? They are ST235-85-16. Thanks


Expert Reply:

The ST235/85-16 tires that we provide all have maximum psi ratings of 80, 95 or 110 dependent on the load rating. For example, the load-range G Provider Radial Trailer Tire, # TTWPRG235R16, has a maximum load rating of 4,080 lbs at 110 psi while the load-range E Kenda Karrier Radial Trailer Tire, # AM32743B, has a max load rating of 3,640 lbs at 80 psi.

You should go with the maximum psi that your tire's manufacturer felt was appropriate for your tire.
