bump to them until they warm up .... have them on my truck & get the same feel but not as bad as i do on the Z I live in New York City. I need new tires for my TT that I am picking up this weekend (just bought it). From reading around I have picked two tires for my stock wheels. I will only drive the car when it is 50 degrees or warmer and I plan to drive aggresively with it from time to time. :1) Dunlop SP Sport 5000 Asymmetrical :2) Potenza RE750 :If you have a better suggestion I am open but I think these two are my best bets... Thanks in advance....
