Do larger tires affect transmission?
Changing tire size doesn’t affect your transmission, but it does change your final drive ratio. The effect is the same as if you had changed your transmission. How much difference you have depends on how different the tires are compared to the stock tires. Larger tires will lower your final drive ratio.
