I was interested in getting these until my tire dealer warned me away from them. He said the cold weather (below 50) performance would be much less than my Goodyear OEMs on my GXP. Since I do drive in cold weather I passed.
A little bit of bullhockey there I think. They are summer tires, and so don't do well in the cold, but that's a lot colder than 50 degrees (nearer freezing). Secondly, I'd doubt they'd ever be worse than the OEM GY Eagles - which are also summer tires.
Having said that, I personally have the Conti DWS (U.High Perf. All-Seasons) since I drive year round. I'll give up the top level of grip for all-year useability.
It all depends on the tire. I had Toyo Proxies for 4 summers on my Mustang, could run the car right up till I put it away in November with the Toyo's. I had no issue. I got Bridgestone Potenza TE-01 (or something like that) and I HATED THEM!!!! I will NEVER buy another set of Bridgestones. The tires flatspotted any time the temp got lower then 50....and would take 10 minutes of driving to round them back out. And I couldn't even get on the car half throttle if it was less then 40 degrees outside without breaking em loose. After that year, my "summer" tires didn't go on until we had a week of at least 65+ and were pulled off in late September.....They were also HORRIBLE in the rain. They hydroplaned constantly. But they were "Formula 1 inspired street tires"...
Never had that issue with the Toyo.
Furthermore (and I know this has nothing to do with the cold weather) I had a belt separate just after 4000 miles and Bridgestone and Tire Rack would do nothing for me. Bridgestone said they were the previous model and were sitting in Tire Rack's warehouse for at least 2 years....and Tire Rack told me it was Bridgestone's issue....so after 2 weeks of yelling at them both, I gave up. So maybe it was just a bad set of tires....but I know where and what I won't buy next time!
Not really concerned with winter driving because I have a Chevy Colorado V8 for winter driving. More concerned with how they handle in wet conditions. The Solstice is just going to be my spring, summer & fall "fun" car.
I would like to thank everyone for their help. I especially would like to thank the guy that pushed me towards aftermarket rims instead of buying stock replacement. I received them today and what a difference rims can make. THANK YOU! LOL
