I am getting ready to buy new tires, and I need to know if its ok to go from the stock size of 205/??/15 to 225/60/15?? I have been told that I can not go 2 sizes up because it will be to wide and the tire will wear uneven? Should I go with a 215/??/15? Or is it ok to go with the 225/60/15? What does everyone think of the Falken Ziex ZE-512? Thanks guys!
