It seems a little counter intuitive. I would think a wider tire would equate to more lateral grip. I'm not doubting you. I'm just trying to understand why the thinner tire results in more lateral grip. You may convince me to the 235's.
Thank you for all the great advice on this thread. Another question to the expert:
I have a 2010 GT with 8.5 x 19 rims. 3.73 axle package. I want to try my hand at autocross next year with car. I'll be buying tires next spring when the season starts. I'm not a newby at autox, but clearly not an expert either. Coming back to it after a few year hiatus. I want to run street (summer) tires and stay with the stock rims. With such a setup, would you go with 245/45-19 or 255/40-19, or ...? Thanks for any advice.
