Reading a Tire Sidewall
The tire sidewall contains important information that tells you everything about your tire regarding the dimensions, construction, operating characteristics and manufacturer.
Why Do Tires Fail
There are a lot of reasons why you see pieces of tire on the side of the road, but most of them are caused by heat. When a tire is traveling down the road, the sidewalls are flexing, which ultimately creates heat.
How Tires are Made
The most common type of passenger tires are radial tires, which consist of one or two casing, or sidewall, plies that are comprised of either fabric or steel cords and aligned 90 degrees to the beads.
What is a Tire Pressure Monitoring System (TPMS)?
A Tire Pressure Monitoring System (TPMS) is an electronic system that monitors the air pressure inside a tire. The TPMS indicator light on the dashboard warns motorists that at least one of the tires on the vehicle needs attention because the air pressure is too low.
How do I know if my vehicle is equipped with TPMS?
Starting with the 2008 model year, all new passenger cars, SUVs and light trucks under 10,000 pounds must have a tire pressure monitoring system. So, if your car is 2008-model year or later, it has TPMS. Only certain models had TPMS prior to 2008, so 2007 model-year vehicles and older may or many not have a TPMS.
There are several ways to determine if you vehicle is equipped with TPMS. The simplest way is to check your owner’s manual and watch the dashboard indicator lights when the ignition is turned to the “on” position. There are two different low-tire pressure warning lights. The standard icon is a yellow cross-section of a tire that looks like a horseshoe with an exclamation point in the middle. The yellow letters “TPMS” also indicate that the vehicle is equipped with TPMS and the instrument panel may include images of the tires on a vehicle with the corresponding tire pressures for each tire.
