Tire size help
Hi guys i was wondering if someone could help me with tire size calculations? Before anyone say it i used the formula that came with the book but my speed still seems to be off about 5 miles and it seems it gets worse the faster i go i am using a gps for the speed comparison. My tire size is 365/60/r20 i also have 456 gears but i put that in so it shouldn't affect what size i put the tires. Thanks for all your help in advance
