Tire Size Adjustment

[Blackwagon]

I am switching from stock 18" to 22" rims with 265/35r22 tires all around, looking for some advices on what to do with the tire adjustment option from the predator tuner?

What are the benefits adjusting the tire size and what happens if I don't do anything?

It corrects your spedometer. If you dont it will show an incorrect mph.

Adjusting the tire size will keep your speedometer accurate.
