one run-flat tire on my z a problem??

Waiz · 02-20-2013, 02:04 AM

I've been doing this for about two years since some bastard slashed my tire and I had to scramble to find a tire so I have one rear tire RF and one non-RF

I can't notice any difference and it's probably been about 10K miles that I have been running them

Well I'm in no rush to get a new tire for it so figured I mine as well get the correct tire for it, especially after reading a lot of threads strongly advising against it. The seller agreed to cover half my shipping cost to return it so I'm fine with that, plus I found the right tire on ebay for only $75 with about 45% life remaining, which is around the same amount of life as the ones currently on the car.

Good idea, you might as well since you're not desperate

Only real issue is the RF is slightly heavier, otherwise no biggie

If one tire is at 9/32 tread remaining while the other is at 5/32 remaining in the rear, is there a good chance I can ruin my differential? I read you should shave it if it's off from the other tire. This buying a used tire thing is really becoming a pita, maybe I should just buy 2 brand new for the rear?

It will wear unevenly but won't affect your diff

At least you're taking the time to ask around instead of buying them and figuring it out after

Ok because I've been reading that anything over 4/32" difference in tires on the same axle can cause issues with the differential? This is mainly for the AWD folks with the STI's and Evo's though from what I understand. So no one would have any problems putting a tire that's about 3/32" off of the other tire on the same axle in the rear?
