This was the first year for me AutoXing and I have done pretty well considering I am new to the sport. I have been entering my SVT Focus in STS class with a set of lightweight 17" wheels wrapped with my stock rubber. The ContiSports have done very well for me but I am buying a nearly new set of tires from a friend of mine that are on wheels identical to mine that I am running on now. They tires are Kuhmo ECSTA MX which I have heard are very decent tires for Autox use, but the tires are a bit smaller then I would have gotten if I had bought them new. They are 205/40/17 instead of the stock tire size of 215/45/17/. My question is which tires are going to be better for my last AutoX of the year? I know that the Smaller sized Kuhmo's will give me a little better gearing while accelerating, but I don't know if they change in tire size will decrease my traction going around corners. Let me know what you guys think.
