{{Note1}}The following methods require the drive tire diameter to be known. A table with some common tire sizes and diameters can be seen [[Gear ratio check#Tire size table|'''below''']]. There are also various places online that can estimate the tire diameter from the tire's size. | {{Note1}}The following methods require the drive tire diameter to be known.

| − | Or, the tire can be measured by running a string around the tire and measuring its length, or marking the sidewall and floor, then move the car ahead one revolution and mark the ground a second time. Then simply measure the distance between the marks for the circumference. A | + | Or, the tire can be measured by running a string around the tire and measuring its length, or marking the sidewall and floor, then move the car ahead one revolution and mark the ground a second time. Then simply measure the distance between the marks for the circumference. A can give a quick answer for the diameter. To find the diameter from the circumference long hand, use the formula: '''D equals C divided by Pi''', where '''D''' = diameter, '''C''' = circumference and '''Pi''' = 3.1416. |
