After a few very fun track days, my front tires have chunked and need replacing. I think I have decided to just replace the front tires by moving the back tires which are still ok to the front and trying to go a bit wider in the rear with the same 4S tires to get a bit more grip in the rear. And better looks..... Anyone have any experience/thoughts on what is best with the 8.5" rims? 245/30, 245/35, or 255/30? Also, what pressure have people found works best for the track? I started at 37 cold which was way too high and lowered to 36 hot for my best time, but that is in the 20's cold which is pretty low for such a low profile street tire. Also, there is still a lot of variation in my driving of this car, so it may have just been better driving and not optimum pressure. Randy Pobst used 245's when tuning the car, but that is all they provided for sizing as far as I can tell. Any help would be great.
