Question:
4.80-12 Boat Trailer Tires Load Range C 6 ply Is this tire suppose to be inflated to 90 psi it just seems high. Thanks
asked by: Rob
Expert Reply:
Trailer tires should always be inflated to the maximum psi indicated on the tire. For a 4.80-12 load range C such as # AM10062, it should be inflated to 90 psi.
The reason you inflate trailer tires to the maximum psi is because trailer tires are constructed with a thicker sidewall to handle more vertical load compared to passenger vehicle tires.
If under inflated the thicker sidewall will lead to excessive heat build up and tire failure. I have included a link to our help article on trailer tires for you.
