Online Tire Size Calculator

[Navigator]

I once used a online tire size calculator to compare my stock Lightning tires to some 20 inchers I wanted to order, it gave ride height difference, MPH difference, gear ratio change etc. Anyone know where this is located. I have exactly 1 inch of clearance getting into my garage & I want a set of 37" MT/R's & am assumeing they will put me out of the garage.

The 37" should really only be a half an inch bigger than a 35".
