Tire age?

[Westernbiker]

I purchased a front and rear tire maybe a year and a half ago. I needed the front tire but bought both because of the deal I got. So the rear tire has been sitting in my garage for that year and a half. It is getting close to being needed. How old must a tire be before we should NOT put it on? Remember, I live in Arizona and it has been in my garage. Thanks for any input or advice.

My son lives next to you in Mesa.
Storage is important. Cool and darkness is good.
I noticed at most shops the tires are stored standing on their tread so I made a small rack to fit the tire.
I look at the tire closely when I mount it for any cracking/splitting on the sidewalls.
Remember the tire your going to replace has been on an additional 1.5 years so replacing it a little early
is good insurance for you. I replace mine maybe a month before a long ride to make sure the tire is road worthy.
Dunlop used to have storage tips on their site haven't been there in years.

It's fine as long as it hasn't been setting outside in the weather. If you wanna ck, just roll the side wall inward and look for checking. If it's there don't use it. Seeing how the front is fine I would think the rear is as well.

I also agree the tire should be fine, but the heat in the summer is very hard on things (tires,batteries etc) in Az. I recall 2 years ago a buddy who winters in Az. hooked onto his boat trailer stored in his garage, moved it out only to find that the heat had welded his tires to the floor. Tore the treads right off the tires where they contacted the concrete. I have no idea what the temp is in the garage when the ambient temp is 110 deg. He stores all his toys on blocks now! We aren't used to that here on the Canadian Prairies.

Also, check the DOT date code on the tire (it may not have been newly made when you bought it). Just sitting in hot storage will cause a tire to age out, because the rubber hardens, and usually 6-8 years is the limit.

Thanks guys! I will check it over thoroughly for cracks and such before use.

WintrSol had a good suggestion re date code check. Here is some info on DOT date codes if you are not familiar.

Twas the night before Christmas and all thru the garage, not a vehicle was stirring , not even the Dodge. The tires were hung on the nails with care, with hopes that Santa would fill them with air.

You just need to check the tire rubber for flexibility and condition. I bought a rear wheel three or four years ago from Pinwall and received it with a new looking Avon that was 11 years old. I took it off and examined it carefully. It passed my tests so I remounted it and wore it out.  Now I know many would frown on this, and I would never recommend.....but use some common sense. It would be hard to destroy an unmounted tire in two years,, even exposed to harsh elements,,,,

if it is a good tire to begin with.

Hey Westernbiker,,, I sure would like to see a picture of the bike that won first place in the cruiser class.

your fine,  go ahead and put it on should last another 4-5 years or so which is probably the MOST you will get out out of it anyways mileage wise.
