Spare too old?

IT's fine, don't overthink it.

Maybe just give a tap every now and then to make sure it is full.

Or, just get road side assistance and don't be bothered with changing spares at all.

Spare in my car is at least 3 years older. It'll most likely be fine as long you don't cracks in the sidewall.

Spare tire should be fine, ideally you would only use it for a short period (to get home or mechanic) and there is a speed limit on the tire sometimes. So should be fine in an emergency however I would not drive on it for weeks.

Am I weird to be concerned topping up this tire? Since it's so old, can't it explode at such a high PSI?

Take it out of the trunk and inspect it all around for signs of aging such as cracks in the rubber, any areas that seem to have hardened, etc. Check the pressure and top it up if needed. If everything looks good then you’re probably good to go another few years. It’s not going to explode in the trunk just sitting there, if it’s going to fail from age then it’ll fail when it’s under load when being driven on. So if you do need to use it in the future just keep the speed low and minimize the distance travelled on it.

Best way to check it is to take it out and let the air out and check for cracks etc then, much easier when you can flex the sidewalls etc more. Then refill it to spec and put it back if good...

It's fine. Just top it up to 60psi once or twice a year.

I am with the rest of everyone here. Would also like to add that the tire in the bottom of your trunk isn't subject to UV, or anything else you pick up off the road - generally should be in pretty good condition.
