I recently purchased a 2008 base coupe that has Goodyear Run Flats all the way around. The two front tires are brand new but the two back tires are going to need replacement fairly soon. If I opted to keep the run flats does changing tire brands on the back tires create any problems. I am also assuming that I need to either run 4 run flats or 4 non run flats front and back.

For street use, you should be fine. I will be doing the same thing, when I wear out the rears on my current set.

It is recommended that you stay with either runflat or non-runflat on all four tires, since they behave differently, due to the stiffness of the sidewalls.

As long as they are the same on each axle you should be fine. Not good to run different brands on the same axle , ie front or back.

At 7000 miles on our 2013 GS, mysteriously, the back tires were worn down to the wear bars. I bought some Bridgestone RE050 A Run Flats, and kept the Good Year run flats on the front. Other than noticing how noisy the Good Years were, no other problems.

WOW . I have never heard of such a thing - ever. Most likely a "factory" defect.

That's exactly how I explained it to my wife!..It's her car!!

No problem unless the tread design is drastically different. They're all radials.

I've never been a fan of mixing tire brands front to back. If I ever did it at, it would just be for a short time, not long term.

I've done it. No problem unless you are operating the car near it limits. I agree with changing brands. I would avoid the Goodyear Supercars. They are probably the worst tire that will fit your car and after 1 year they get hard and wear very fast.

A Corvette should've the same tire on all four corners. If you must have different tire brands on the car just make sure that they are on the front or back, never on different sides. I would never mix a run-flat and non run-flat on the car.

If you have driven any distance on the run flat without air, check the interior of the tire before repair. I had a nail dead center in the tread which would have been repairable but once the guy took the tire off the rim and looked inside, there was a crack between the sidewall and tread but only visible from inside. He said it was from driving on it with no air. Had he just plugged it, I'd have been driving on borrowed time.

Most RF's that are run without air, even for a short distance and low speed, are toast anyway and usually have to be replaced.

Yet another one back from the dead.

I've had them on two different Corvettes and I'm not a fan of run flats.
There are four major issues with run-flats:
After you drive 50 miles on a "flat" run-flat, it must be replaced.
They are very difficult to find when you are in a pinch.
They are expensive.
They add extra unsprung weight to the car.

On my C6 I had a run flat go flat in Las Vegas. The nail was within 1 inch of the side wall and they would not repair it. It was going to take a week to ship in a replacement run-flat. I had to buy two new non-runflats to get home.
Now I carry a small 12v compressor, a plug kit with a towel and a small vise grip. I've been driving like this for over 15 years and never been stranded. The TPMS comes on when the tire gets down to 23psi. Usually you find its a nail or screw and you simply add air to the tire and drive to a repair shop. If it's a blowout, then it just doesn't matter if it's a run-flat or not.
