Hi all, I would like to use widers tires on my x for better control and cornering, of course, without losing soft ride. Currently, I am using 17" rims with 235/65/17 tires. Can I change them with 255/60/17 tires without changing my rims? I understand that the original setting is 255/55/18 with 18" rims. However, it is pretty expensive to change rims, so I have this thought. Is it feasible? Any input will be much appreciated!
