My spare is 13 + years old, never used. Checked the pressure recently and was told by my tire guy that it's too old and should be replaced. Wouldn't even fill it with air for me. Does this sound right? Do I really need to replace it?

Due to dry rot and such, I wouldn't personally feel comfortable riding around on a tire that old, even for a short time and even though it may have zero miles on it.

Is it a temp donut spare or a full-size rim/tire?

Look at it. Is it all full of tiny cracks? (Use a magnifying glass if necessary).

I have used spare tires that were 40 years old and they were fine. I have had spares that were decayed at 10 years.

If you fill it, keep your face away from it and definitely wear good safety goggles while filling. Inspect it both before and after filling it.

Given you can get a decent used tire installed for $30 - $50 why not just replace it?

Usual problems with old tires are due to ozone or ultraviolet light, neither of which gets into your trunk much. Some of the essential oils will have dried out, though. There is a date code on all tires so check all your tires to be less than 6 years old.
OTOH, since you apparently needed help filling the spare with air by yourself, are you really that likely to change a flat?
I would go to a used tire store and buy whatever fits and store it in the trunk for another 13 years.
Another alternative is determine which two of your tires are the worst. Buy new replacements for them to put on the front. Keep the best of the take-offs as a spare.
YMMV

Just trying to save a buck. I guess the smart thing to do is replace. Thanks.

I was at a tire shop getting new tires. Asked the service guys to check pressure on spare to save me the trouble. Thanks

If it's only going to be used for a spare, I'd air it up and keep an eye on it. It your car is 13 years old, you're probably due for another vehicle anyway.

It is not exposed to sun so deterioration would be limited. I have used spares that are over ten years old without problem.

Cheapest option would have been to mount one of the tires you are replacing with best tread onto the spare(presuming you didn't run them all down far below the wear markers. Keeps your spare up to date that way.

I have some rear tractor tires on an old tractor that are at least 40 years old. I have kept them aired up and never ran them low and they are still good. I have sprayed the sidewalls with protectant. A 13 year old spare would not bother me at all. Have some around here that are older than that.

How fast is the spare losing air would be my first question and that would depend on when was the last time you put air in.

I used a 55 year old spare on a Model A Ford last year... the tire was in the side mount and the car was restored in the mid 60's...

When I buy tires I always check the spare and if in doubt I have kept the best tire coming of the car and made it the spare...

Few people today change tires on the road... at least here.

If you use a spare so you can drive in for a repair it has done it's job... even the space saver spares will often say not for over 45 mph or 50 mph along with temporary use.

I own 50 vehicles... almost all are collector cars and I have never bought tires based on a calendar date.
