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

Waiz

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

What tires are they?

Same as you dude!

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

Wow, I never knew this would turn into such a ordeal. Now it looks that not only is there a run flat version of the RE050a's, but there is also 2 different regular versions as well. One with a speed rating of "Y" and the other with a "W" speed rating. I guess the 370z's come with the "W" speed rating from the factory, which means I should make sure the used tire I buy is also a "W" speed rating? It sucks because the one I'm looking at for only $75 is the "Y" version.

Going higher speed rating is not a big deal. Going lower is the issue. Take the (Y) rated tire. you will be fine.
