It is getting time to replace the stock tires and I plan to go with the Hankook Ventus v12. I cannot decide if it would be better to go with the smaller diameter 255/35 or the taller 255/40 for the front? Do you want your front tires a little taller or a little smaller (diameter) than the rear? I tried search but couldn't find the answers I was looking for. Thanks for the help!
