225/50/16 is a good size, but "50=taller tires" ?
50 means the profile is less, rather at any given point on the sidewall it will be about 0.5" smaller than original tyres..
But 225 is TOO wide, and the point you made, "for better grip", is irrevelant since he's in KHI. Where is he going to make turns at 150 kmph in KHI :s?
