Take 1 - {[front width x .(aspect ratio number of front)] / [rear width x .(aspect ratio number of rear)]}

Make sure that number is less than .01 or 1 percent

So a car with 235/35 and 275/30 would be 1- (82.25-82.50) = .003 = .3% difference in rolling diameter, these sizes on 19 inch wheels is ideal for staggered xi setups, that's what I am running with my Morr vs8.2, no issues whatsoever.

Good luck!!!
