RV Tire Safety
with RV tire expert Roger Marble
I have written a number of articles on the advisability of running trailer tires at the inflation molded on the tire sidewall.
Some posts dove deep into the science behind the recommendation. I know this can make your eyes glaze over, so how about just following what Goodyear says in their RV Tires information webpage:
“Unless trying to resolve poor ride quality problems with an RV trailer, it is recommended that trailer tires be inflated to the pressure indicated on the sidewall of the tire. Trailer tires experience significant lateral (side-to-side) loads due to vehicle sway from uneven roads or passing vehicles. Using the inflation pressure engraved on the sidewall will provide optimum load-carrying capacity and minimize heat buildup.” [Emphasis added.]
