Wheels and Tires sitting in garage, still good?

I've had a set of brand new wheels and tires stacked in my garage for about 6 years now. Would there be any problem using them when the time comes?

tires are probably going to be harder and slicker that when new.

tires could fail. 6 to 7 years is normally considered max. I once bought a set of tires that was several years old without realizing it (from a store). on my first weekend trip I through the tread off of 3 of the 6.

It will depend. If they have been stored in a dry area out of light, they probably are fine. The risk is dry rotting and cracks. I have used older tires and never had a problem. For a limited use car such as my Corvair, one that does not travel at extended high speeds I would not be too worried myself.

My daily driver still has one of it's original tires left on it. (It's and '89 Acclaim) It is showing signs of dry rot on the sidewall, so I am going to replace it soon. As jrdriver8 says, if you aren't driving it on the highway for extended speeds, they'll probably be fine.

You should probably verify the date code because they could very well be MORE than 6 years old....

Is your safety worth the cost of new tires?

That's the question I recently answered with my now-out-out-of-group-red!!! Corsa. Tires looked perfect, less than 3,000 miles, but one had gone flat and sat on sidewall for some time. Was going to replace that one for sure. Then realized they are all 15 years old. Replaced them all, kept one to become the spare.

We have talked about it before - there are about 10,000 factors that go into whether a tire is still good after sitting. Weather exposure, light, humidity...

A good rule of thumb - 8-10 years. That being said, I have tires that are over 10 years on my Brier, the durometer is still good, wear is even, and I am not worried.

After 8 years I'd be a little concerned.... look for ANY spider cracking on the sidewalls on both sides.

I just skimmed through the NHTSA report on the subject. Two things jumped out: 1) On road use, particularly in hot climates is where degradation happens and it looks like the 8-year number is accurate for very hot climates. 2) Stored tires (spares) did not degrade significantly over the same period.

Heat cycling was deemed to be the culprit.

Craig is right - heat cycling, combined with Ozone (the yellowish blue haze that seems to stick to tires after sitting in traffic) cause a significant portion of damage that causes shorter tire life.

As a fomer Quality Engineer for a major tire company, I have some knowledge in the area of tire inspection - which is why I am comfortable on my 10 year old tires, but I know them inside and out.

I had some Michelins I bought new for my minivan. After 4 years, and about 8000 miles, all 4 had good tread, but all were showing cracks in the grooves of the tread. They pro-rated them, but had to replace with same brand and cost me another $100 for the replacement. Never had tires go bad so quick.

On the other hand, I'm still running 3 digit date codes on one of my AMC Eagles. The tread is hard, but shows no signs of cracking or spidering anywhere. I guess that's stretching it, since they were made in '99 IIRC.

All of my cars are freeway drivers, even the real old ones. Cruising at 70 mph is common.
