I'm running BFG Super Sports, an all-season, non-run flat. I like them a lot, very reasonable price. If you want a little more performance and sexier side wall and tread, go with the BFG G Force KDWs, it's an older design tire but seems to be the standard to beat for UHP tires.

all the tires are pretty good now adays....just a matter if you want runflats or not. I had some Firestone Wideovals on my last Z and they were a good tire for the money. Shop your purchase around....check sam's, BJ's, tire rack, firestone...etc.

I have Firestone non runflats and have 2 comments: 1) great traction in warmer weather - noticably different when it turns cold - but not unsafe, 2) within the first month I had the C5 (two years ago) I got 2 screws in the same rear tire (2 separate occurances). I plugged the two different holes with the gooey worm looking things using the reamer and t handle inserter and have no issues with the plugs. I did have the tires rebalanced and dont go over 90 or so ever. Still holding after 17000 miles.

with DaveThe GS-D3's have a treadwear rating of 280. The BFG KDW's mentioned in this post are rated at 300. Not much difference at all.
As with any tire, you must use your head when it gets cold, understand the laws of physics, understand when it's below 32 it's not the optimal time to be driving your car in a spirited manner and maybe give a little in those few times when it's colder than normal. There are NO tires made for performance driving on cold pavement... When it's cold, you need to give it a rest and drive accordingly......

...a word of caution: KDWs are horrible on wet surfaces, They should be considered dry surface tires, only. The KDW2s are much better on wet surfaces but are noisier than most ultra-high performance tires.
I'm in for the Nitto Invos, look cool and handle awesome
If we rated tires on tread design, the Nitto Invos would score high. The slashes that crisscross intriguingly through the tread had us envisioning a vicious Star Wars light-saber showdown taking place right there on the edge of the tire.
Unfortunately, the Nittos’ performance was less inspiring. They were second from the bottom in both dry lap time and braking, with both drivers reporting a soft feeling at the limit and that they were difficult to drive precisely because the grip would taper off in a nonlinear fashion. This led to more oversteer than most of the other tires exhibited, and even though they had an average skidpad run (0.91 g), the Invos left both drivers wishing for more grip.
Things were better in the wet, where Geswein ranked the Invos tops for precise responses, tied with the Dunlops and the benchmark Michelins. The tires’ predictability inspired confidence, although their lap time was still exactly in the middle.
Fairly quiet on the street loop, the Invos were below average in the dry and average in the wet, which put them in eighth place. Nitto does offer a higher-performance tire, the NT05, which conceivably could have fared better but is not available in the size specified for our test.

The next time, I'm going with PS2's I'm not worrying about the cold tire needs being in FL and I'm not going to take any winter trips in it. Now trying to decide between the non RF PS2 and the PS2 ZP is the current consideration. The PS2 ZP is the OEM tire for C6 Corvette ZR1. The stance of the A/S is not as wide appearing or as aggressive as the PS2. The PS2 ZP is on the same line tire as the OEM F1 EMT. Except it is newer generation. I cannot remember the wear rating on the PS2 vs PS2 ZP though. It can be found on tirerack though.

I also run Falken Azenis RT-615s 315 30 18-255 40 17 they are sweet and less than 1k shipped. What a suprise after runflats seems like defferent car.

I've had the Firestone Firehawk runflats. Awesome looking tread pattern and nice tire that got about 30K miles. I just replaced them w/ the Michelin PS A/S Plus ZP's. totally different tread pattern and maybe not as wide, but really ride nice. I think the sidewall is bigger than the firehawks as it really looks taller now...maybe it's just the extra deep tread on the michelins. Both are great runflats.

Dont mean to hijack the thread but since we are discussing tires. I usually buy the runflat Kumho all season from tire rack, they are alright, affordable. My question what are cons/ pros between runflats vs non-runflats other than if you have a flat tire u can drive few miles before trashing the tire.
Thanks

BUT Goodyear has discontinued them in the 275 40ZR18 size that we need for the rear of our cars. I just had a set installed that I got from Tirerack. At the time I ordered the rep told me they were down to 6 tires left at the warehouse in NV and all the other warehouses were sold out.
