Spare tire age

The set before this set, I bought 5 and kept it rotated in with the rest. Last time this past summer, I only bought 4 and kept the best out of the prior set. I always keep it covered. It should age out about the same as the rest of the tires. I want to know it will be there for me when I need it.

The illusion is a newer tire is a safer tire.

A worn, bald, debonded, checked or over stressed tire is bad whether it is six months or six years old.

Maintenance and road hazards are my biggest tire concerns, no matter what they are mounted too.

When I change my trailer tires out every 5 years I keep 2 for my spares (yes I carry 2 spares) So my spares are never older than 10 years.

Every three years when replacing tires on TT I keep one of them and replace the spare. Spare is never older then 6 years.

Who wants "luck" with a spare tire and risk a blowout & expensive repairs or family safety? Heat is the major killer of tires and spares are sitting there exposed to the elements. UV rays (if no tire cover) and ozone also damages tires. Visual appearance should never be used as a deciding factor. The best info. will be from a tire manufacturer or a tire engineer. RVtiresafety.net is a blog run by a retired tire engineer, ex-racer and avid RV-er and has tons of excellent info. including tire aging and life expectancy.

Without question, unless newer than what's currently on the axles, replace the spare along with the other 4 (or 2). I'm replacing all 5 of our tires at the end of next season after 5 years of use. It's just part of the cost of owning and operating an RV.

I have had good luck with old spares. If they are covered and look good, they usually are. And...I put my spare on and head for a tire store, I don't drive indefinitely on this spare as some do.

Safety knows no price. If I am replacing tires because they have aged out, I replace the spare too. My family's safety is worth the price of one more tire.

We were camping with family last summer, it was very hot, windy and miserable outside in heat of the day. I told my BIL that I had a cover that I had found that I would give him to cover his spare tire. It was many years old and looked brand new still mounted to the back of his trailer. I was sitting outside after it cooled down some and looked over at this spare, it looked odd so we went and had a look. The tread had split a third of the way around the tire. It was rotten for sure. His awning was the same age and a gust of wind ripped that off too. All in all we had a good trip, him not so much. He did replace spare and I gave him the cover I promised.

Replace the spare..
