Tire RulerWhat changes when you switch to 225/60R16
- Height: +0.47″ (+1.8%), so ground clearance at the axle goes up 0.24″.
- Width: +0.39″ (10 mm). Check inner clearance to the suspension and frame, and the fender liner at full lock.
- Sidewall: +0.24″. A taller sidewall rides a bit softer and protects the wheel off-road.
- Revolutions per mile: 771 → 757. Your gears act about 1.8% taller; at 65 mph in a 0.69 top gear with 3.73s, that’s 2,150 → 2,112 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.
