Need your expertise on a tire sizing issue. I have a 94 stock with original 16/17 inch wheels. I have been running Toyo T1R on the car for quite a few years and I am happy with the predictability of this tire. I replaced the fronts about 5 years ago and they are like brand new. Time for the rears but Toyo doesn't make 245/40/17 in the T1R. I found a pair of 245/35/17 on the net. My question is, would going from 40 to 35 profile cause any real problems with handling or tcs? I don't really want to go a whole new set of different brand tires at this time. Any advice would be greatly appreciated.
