A taller tire also raises your overall effective gear ratio. You put lower gears in your car for better off-the-line performance and then couple it with a taller tire, your overall gear ratio will be higher. For example, with 3.73 gears it would be like putting in 3.5x, 3.6x or whatever, depending on what tire size you started with and then what you changed to. Just wanted to clarify that because so many people call numerically higher gears high gears when in fact, the higher the number, the lower the gear.
