Re: Tire size formula
Example 205/55 16 ..........Tire size (205) divided by 25.4 = 8.07inches
(tread width) X .55 (Aspect Ratio 55) X 2 (cuz you need height from rim to
ground and rim to top of tire for dia) + 16 (rim diam) = 24.88 total tire
wheel dia (+.20 over stock) (this is what I'm running on a 16 X 7.5 BBS
wheel on my 5ktq)
205/60 15 = 205/25.4 X .60 X 2 + 15 = 24.68 stock
225/50 16 = 24.85 (+.17!!!!) how bout those fenders???!!!!
