| He needs to go with 18's or larger. The smaller sidewall on the tire the better because it is stronger allowing it to better withstand the pressures of going over 175 mph.... You could do what most exotics do or nsx guys do, run a staggered set so you keep the large diameter in the rear while maintaining a small sidewall. Like 18's in the front and 19's in the rear. 18's tend to have more tire sizes/support though.
