Tire RulerWhat changes when you switch to 295/60R20
- Height: +0.94″ (+2.9%), so ground clearance at the axle goes up 0.47″.
- Width: +0.79″ (20 mm). Check inner clearance to the suspension and frame, and the fender liner at full lock.
- Sidewall: +0.47″. A taller sidewall rides a bit softer and protects the wheel off-road.
- Revolutions per mile: 611 → 594. Your gears act about 2.9% taller; at 65 mph in a 0.69 top gear with 3.73s, that’s 1,704 → 1,657 RPM.
Sizes are theoretical, from the sidewall code. The same size can differ by a few tenths of an inch between brands and tread patterns; check the maker’s spec sheet for the exact model.
