I did a search about tires and only found one thread response about tires. As a beginner tuner I've noticed that some tuners state "sports hard to sport softs". The same type answer about Comfort and Racing tires. I was reading the November issue of Motor Trend where 12 cars were tested hot lapping Laguna Seca and had a drag race with all 12 at an Air Force base. The results were listed and there were several tire choices from Bridgestones, Michelins, Goodyear to Pirellies. The Michelin Sport Cup II being the tire with the best traction with Pirelli P Zeros a close second. Here is the only result I found about tires in GT6. GT6 .............. Real World Race Soft = Pure fantasy Race Med = Pure fantasy Race Hard = The softest qualifying tire imaginable Sports Soft = Race Soft Slick Sports Med = Race Med Slick Sports Hard = Race Hard Slick or Soft Track Day tire for street cars Comfort Soft = Soft Sports Tire or Semi Slick Comfort Medium = Soft Street Tire Comfort Hard = Your Average Street Tire For every hot car I've had I have used Pirelli, Yokohama and Michelins. All 3 once they have warmed up seem to have close to the same grip when driving on the street or an autocross in a big parking lot and a few track days that I was fortunate to be able to run. I'd really appreciate a response from any tuner that has also raced in real life events like the SCCA or someone that has worked in a tire store that has the experience to make an educated statement. How is the choice of tires directly related to the tune? Please let me know what you think or have experienced. Thanks in advance. BTW If there is a thread that has already discussed this topic please post the link or to the Moderators move my post to the proper place.
