"For Safety the rule of thumb is to replace tires when they reach 5 years from the date of manufacture. They may last longer with proper care but the odds are against you beyond five years of age. "
Wow...is this really the expected lifespan of trailer tires? I have LRG Goodyears on my 2014 Cedar Creek, and I was expecting to get the 10 year lifespan that is normal on past motorhomes with 22.5" Michelins. My rigs live in a garage when not traveling and protected with 303, so no sun abuse. Is there that much difference in the quality of trailer tires?
