Should Trailer Tire PSI Match Sticker on Trailer or Number on Tire Sidewall
Question:
I have a 2017 Rockwood Windjammer 3025W Travel Trailer. Had a blow out with the original tires. I replaced the tires with ST225/75R-15 Goodyear Endurance tires. The psi on the sidewall of the new tires is 80psi and the sticker on the travel trailer advises 65psi. Which pressure should I go with to ensure safety and proper wear on the tires ? The replacement tires are the same size as the original tires Thanks !!!

Helpful Expert Reply:
Trailer tires should always be inflated to their maximum psi as listed on the sidewall of the tire itself. This means you should inflate the new tires on your trailer to the 80 psi that you mentioned in your question. The sticker on the trailer refers to the psi that was listed on the stock tires.
It sounds like you replaced the factory tires with units that have a higher load range capacity, which explains the jump in maximum psi.
I have attached a great article on trailer tires that you might also find helpful.
