Re: Got a tire rating question bout towing boat
There is another active thread talking about tire life. They're talking about 7-10 years as the maximum age for tires. I just had a trailer tire blow out the other day. I have no idea how old the tire was but it was pretty well checked and cracked. Had plenty of tread. The only thing it broke was a running light lens. We were in a place we could pull over but 20 miles before that were were on two lane, winding, mountain roads. Could have been a lot worse.
I replaced the trailer tires and the spare yesterday. Also went up one load rating. Yes - it seems a shame to throw away tires with plenty of tread left but in the case of trailer tires, the overall condition is more important than tread.
