Spare tire

Question, just bought my 02 TJ in February. Just recently found out that the PO installed 31x10.5x15s while leaving the spare the original 30x9.5x15. Is it ok to run this spare if I have a flat or will using the spare with that size which is different than the others damage something in the drive train. I don't mean using the spare to rotate in or anything, just using in an emergency in case of a flat to get me somewhere to repair the flat. Or should I replace the spare with one of matching size to the other four.

Thanks in advance

If you run it on an open differential axle (no locker and no limited slip) it will be OK.

I'd just add that I wouldn't do this for a long time. It will be OK, but those spider gears are going to be getting a major workout and long term driving like this will likely cause problems. I'd just do it to get back home.

Just like going around a very very large circle many times.


Sgravess, I was in the exact same boat, I kept an eye on craigslist and found a 31" used tire for $20, found a local shop to mount and balance for another $5.

Then sold my 30" the same way.

Don't know what part of Minn you are from but this is just an example. Just keep a look out and you will find a deal.
