Another new owner question............Do you run non-flat or regular tires on your C6?.........How much tire pressure do you use?..........Tire recommendations are welcomed.
Thanks in advance, Steve

I run non runflats and I have the tires at 30 psi cold.

Glitch with a non run flat, is you do get a flat, you need to find a place on the road/highway that you can pull over safely, and level and enough to patch a flat with a plug kit in the first place.

Tires, just depend on what you want. The standards for the the Vet for a summer performance tire is the michelin super sports, which can be had in both run flats or not.
Now the glitch, since the tires only hold there grip for about 4 years before the rubber starts to get hard and they need to be replaced over just tire wear, so weight how much you are gong to drive the car in 4 years, against what tires you are are going to get.
Hence if say you are only going to drive the car for 10K in 4 years, don't want a run flat, and more grip that the SS's are going to give, then R888's. The down side, the R888's can get scary in the rain.

As for tire pressure, this will you need to play with. Ideally, around 32psi with the tires stone cold is the norm. This will bring the tire pressures up to about 36psi when the tires get hot, and keep the sidewall deflection to a min for corning.

Do a search here on the forum, there are a lot of threads on this subject. I run NON RFT 30PSI cold on the rear for traction and RFT on the front 30PSI.

Thanks for the replies...........keep them coming. I used the search mode, but got info for all generations.. Do the run -flats handle as well as regular tires ? I have heard that the run-flats are louder too. Is that true ?
Thanks, Steve

Runflats for me. It just depends on how much of a gambler you are. Ever tried to plug a tire at night on the side of an interstate? Runflats give you a security blanket.

Stoney Wide Oval NRF's here. Have a tire plug kit and compressor in trunk if (Hopefully never) needed. As with all the other threads about this issue, you're gonna get more opinions than you'll know what to do with. Good luck in trying to sort them all out !!

Nice Ride

Run flat will likely get you to the repair shop while the non run flat will not. Think you will be most happy running the tires designed for the car.

Run flats. The issue for me is that I insist on a flatbed tow, which can add 45 minutes or more to the wait for a tow truck.

JJLAI724

Regular tires for me. The nail always plug the hole and I don't know it's there until I see it.

Been lucky so far on not getting a flat on the road.

I've been using non run flats now for over 10 years, without a flat. Carry a repair kit and air compressor just in case if you go on a trip.

Run flats are a much harder compound and stiffer tire, hence run flat. I drove my C5 home 700 miles with 11 year old OE run flats. 30 minutes into highway portion of the trip I was second guessing what I had just bought.

Once home I replaced the run flats and it was a totally different ride. The installer had me sit on one of the run flats after it removed from the rim, it barely moved. The non run flat I could collapse flat.

I keep a couple cans of fix-a-flat in the back just in case.

Same here.

I have always stayed with the run-flats.

I have non-runflats, better ride, tire pressure set 30PSI cold, and belong to AAA Plus member.

Running Michelin Pilot Super Sport run-flats that now have about 5K miles on them. Love the handling and ride but since its a convertible and performance sports car I don't expect it to ride or be as quiet as a luxury sedan.

The only downside that I've seen with them so far is poor traction at colder temperatures which shouldn't be an issue if you live in warmer climates and they are a performance summer tire. Running at 30 psi inflation.

When the car had the OEM Goodyear Eagle F1 tires on it the car didn't feel stable and had a tendency to wander and be pulled off course by ruts in the pavement. I had a major 4 wheel alignment done when the new Michelins were installed and it cured the problem.

Is the entire tire a harder compound ?....or just the side walls ?

itomh

Non-runflats for me. I enjoy the smoother ride

Jeff T.

Depends on the tire. I just Googled a little and it appears there are a couple methods to achieve a RF. Sidewall reinforcement appears to be most popular though.

You don't say what model you have. Fewer choices available if you have a wide body (GS, Z06, etc.). For instance, the R888 is not available in wide body sizes.

I run non-runflats at 30 psi cold.
