Be sure to prep the tire surface for a proper durometer reading. Take a small scraper and remove any debris from the tire surface. Removing debris requires little effort on hot tires. Cold tires require a little elbow grease to get down to the true tire surface. Any debris left on the tire surface will cause false readings. If you are checking your tire wear with a tread depth gauge you need to remove all debris also. Durometer hardness is only part of the tire equation. Tire compound, chemical composition, tire tread, sidewall design, heat cycles and tire wear are all factors that affect the performance of your tires. Considering all the variables and using your durometer measurements will help you to select the right tire for the right conditions. Proper use of the durometer will allow you to track the condition of tires, giving you the chance to replace them before the tires get too hard for proper traction.
