What gear ratio do I need for 26 inch rims?
Calculating Equivalent Drive Ratio With 28-inch tires, you would need a 3.82 rear-axle gear to match vehicle performance with 26-inch tires and 3.55 gears. Since a 3.82 gear is not offered for most rear axles, you will need to choose a gear between 3.73 and 3.90 to get close to the optimum.
How much does tire height affect gear ratio?
generally 1 inch in tire diameter eqauls 1/10 gear ratio, so a 1 inch shorter tire would put the gearing at 2.83. some cheap/free 3.08’s would do more good than tires.
What happens when you change the gear ratio on a tire?
