Despite advances in tire technology, tread life is finite and will vary by car type, tire type (such as all-season or high-performance), driving aggressiveness, and even road and weather conditions. You need to replace your tires a few times or more throughout the life of a typical vehicle. As the adage goes, nothing lasts forever.
Proper maintenance and responsible driving can maximize the mileage in a set of tires. Monthly tread inspections can inform when the tires warrant replacement, well in advance of the federally mandated treadwear indicators. And when it comes time to buy, you can use CR treadwear ratings to find tires that promise a long service life.

Tire Pressure Monitoring Systems
Tire Pressure Monitoring Systems (TPMS) have been standard equipment in all new cars since the model year 2008. Since their introduction, government studies have found that the systems have led to a significant reduction in underinflated tires on the road, benefiting fuel economy and safety.
The federal requirement stipulates that the car be able to monitor the pressure and alert the driver when it drops significantly, but it does not specify the technology. Many wheels are fitted with sensors that monitor the pressure and send the data wirelessly to the car’s instrument panel. These systems, called direct TPMS, may require batteries that must be replaced after several years, often leading to replacing the entire sensor. Some just alert of pressure loss with a warning light, but better systems provide a readout of the pressure in the tires.
Indirect systems rely on the antilock brake systems to measure wheel speed and interpret the pressure. These systems don’t use pressure sensors and therefore cannot display pressure.
How to Read a Tire Sidewall
Tires have a wealth of information encoded on their sidewalls. When replacing them, we recommend staying with the size and speed rating of your car’s original tires. Check your owner’s manual for more information.
Size: On the tire below, 215 is the cross-section width in millimeters; 60 is the ratio of sidewall height to its width (60 percent); R indicates radial-ply construction, and 16 is the wheel rim’s diameter in inches.
Load index: Shorthand for the weight each tire can carry safely. The 94 here means 1,477 pounds per tire—pretty typical for a midsized car tire. That’s the maximum tire load.
Speed rating: A letter denoting the tire’s maximum speed when carrying the load defined by the load index—and not how fast you should drive! Standard all-seasons are usually rated S (112 mph) or T (118 mph). Climbing up the scale are H (130 mph), V (149 mph), ZR (149-plus mph), W (168 mph), and Y (186 mph) ratings. Winter tires may carry the letter Q (99 mph) or higher.
Treadwear grade: A government-required number that indicates a tire’s expected wear. A grade of 300 denotes a tire that will wear three times as well as a tire graded 100. But the numbers are assigned by tire manufacturers, not an independent third party.
Traction and temperature scores: Those scores denote a tire’s wet-stopping ability and temperature resistance. For traction, AA is best, C is worst. For temperature resistance, scores range from A (best) to C.
Manufacture date code: Every tire has a Department of Transportation number after the letters on the sidewall. The last four digits show the week and year the tire was made; for example, the digits 2315 would signify that the tire was made during the 23rd week of 2015. Don’t buy tires more than a couple of years old.
Longer-lasting tires make safety checks more critical than ever. Many of today’s tires last 50,000 miles or more before they wear out, though heat, environment, potholes, and underinflation can weaken them.
Keep Your Tires Safe:
• Check the air pressure each month when the tires are cold (before they’ve been driven more than a couple of miles). Be sure they’re inflated to the air pressure listed on the placard on the doorjamb or inside the glove compartment or fuel-filler door. Don’t use the pressure on the tire’s sidewall; that’s the maximum pressure for the tire.
• Look for cracks, cuts, or bulges in the sidewall or tread, and replace tires that have them.
• Check for uneven tread wear, which typically denotes poor wheel alignment or worn suspension components, and has both checked by a shop. Also have your vehicle’s alignment and suspension checked before mounting new tires, to prevent them from wearing prematurely.
• Stay within the vehicle’s weight capacity listed on the doorjamb placard. Overloading makes tires run hotter, increasing the chance of failure.
• Measure tread depth with a quarter. If the top of George Washington’s head is just visible when placed in a thread groove, the tread has about a 4⁄32-inch depth. That’s enough to offer some all-weather grip, but it’s time to start thinking about a replacement.
