  • You need to know your vehicle's options to find out the original size of the tires for your vehicle because automobile manufacturers often use different wheel and tire sizes for different variations of a specific vehicle.

If you do not know your vehicle's options, check one of these places: 

1. The original sales invoice or window sticker when you bought the vehicle.

2. Your vehicle's Owner's Manual, which will sometimes identify your vehicle's options.

3. Look on the vehicle itself. Some vehicles have a decal or lettering that indicates the options located on the side or rear of the vehicle.
  • Find the exact tire quickly using your tire size. Check your owner's manual or tire sidewall to find the required specifications.

    Knowing your tire size can help save time at the tire retailer. It also enables you to make an informed tire purchase.<br><br>You can find your vehicle's original equipment tire size in one of the following places:<br>1. On the tire placard located on the driver's door jamb <br>2. In your owners manual<br>3. On glove compartment door<br> 4. Inside the fuel hatch or trunk lid<br><br>You can also check your existing tire's designation on the sidewall. However, there is no guarantee that these are the original tire size unless they came on the vehicle new.<br><br><div><img src="/assets/mi/system/images/contextual-help/R2-Size.png"></div>

  • You can determine your tire type by looking at the tire's designation on the sidewall of your tire. The following describes the differences between the tire type designations: 

 P-Metric: A uniform designation of tire sizes in metric measurements. A typical P-Metric tire is P205/70R14 93S.

 European Metric: This system was a conversion of the numeric system from inches to millimeters. The aspect ratio appears in the size designation in most cases where it is other than 82. A typical European Metric tire is 185/70R14 88S 

 Light Truck-Metric: This system is used for light truck tires, and it mirrors the P-Metric system used for passenger tires. A typical LT-Metric tire is LT245/75R16 120R.

 Light Truck High Flotation: This type is for light truck tires with lower sidewalls and wider treads that yield better traction on surfaces such as sand and soft soil found in watery, off-road situations. A typical tire is 31X10.50R15 LT LRC
