Chances are unless you are a top driver, 215, 225, and 235 are all going to be very similar in times. The only tire which comes in 235/40/17 is the ZII right now. I have heard from some who have tried different sizes the 235/40 ZII is the better tire due to both grip and gearing.

I have 225/45/17 BFG Rivals on the stock rims, I think the acceleration is slightly worse than the stock sized tires, but I gain a couple MPH in 2nd gear.
