Look along the rim of your tire. You should be able to find a group of numbers separated by slashes and/or dashes. There are two general types of tire sizing, metric and english. A metric size will look like 100/90-19 and an english size will look like 4.00-18. Note, english sizes don't have an aspect ratio, leave that field blank.
