Car Tire Specifications

When you buy new car tires, you’ll either go online and enter your car’s year, make, model, and trim or give that information to someone at a store. Unfortunately, the tire specifications you get in response will not necessarily be correct. For the past 13 years, I’ve been buying car tires for my 2003 Honda Accord DX and the tire specs I’d be given are

This information was taken from and from the tire specialist’s computer at a Costco Tire Center. It says that my tire size is P215/60R17. The tire specs in the driver side door, however, says this:

When to Change Your Car’s Tires

Tread Depth

In the US, car tire tread depth is measured in 32nds of an inch. New tires typically come with 10/32” or 11/32” tread depths, and some truck, SUV and winter tires may have deeper tread depths than other models. A tire is legally worn-out if the tread depth is 2/32nds.  Therefore, a typical tire that starts with 10/32″ of original tread depth has only 8/32″ of usable tread depth. A tire that started with 10/32″ of original tread depth and has worn off 4/32″ (down to 6/32″ of remaining tread depth) is 50% worn. Though 2/32nds of tread depth is the legal minimum, you should change your tires when they reach 4/32nds of tread depth. At tread depths less than 4/32nds, you may experience hydroplaning when driving in the rain and lose control of your vehicle.

Tread Depth Gauge

There are manual and digital tread depth gauges. I’d go with a manual one so you don’t have to worry about replacing a battery.
