Wheel Basics

Rim Diameter

The size of the wheel as measured across its center.

Rim Width

The width of the wheel as measured across its barrel from the front rim to the rear rim.

Bolt Pattern

The bolt pattern indicates the arrangement of lug holes and consists of two elements: the number of bolts, or lugs, and the distance between them across the center of the wheel (in millimeters).


The offset of a wheel is what locates the tire and wheel assembly in relation to the suspension. More specifically, it is the measured distance between the hub mounting surface and the centerline of the rim. It can be either positive or negative, and is typically measured in millimeters.

About Tire Size

About Tire Size

Tire size is an expression that defines a particular tire in terms of its width, height, rim diameter, aspect ratio and construction type.
Staggered Sizing: Different size tires in the rear

Some vehicles come with different size tires on the front and rear of the vehicle; this is called staggered sizing. Please check your owner’s manual to verify whether you need tires with different sizes.

Section Width

The linear distance between the outside of the sidewalls of an inflated tire without any load on it (this does not include any sidewall decorations).

Aspect Ratio

This is also known as the Section Height. This is figured as a percentage of the section width. A tire size of 215/60R16 would have a section width of 215 millimeters and a section height of 60 percent of 215 millimeters.

Rim Diameter

The height of the rim or the longest straight line that can be drawn between any two points on the rim.

Load Index

The load index refers to the load-carrying capacity of a tire, or how much weight a tire can support. For example, if a tire has a load index of 89, it can support 1,279 pounds at maximum air pressure.

Speed Rating

The speed rating of a tire is based on U.S. Government standards for reaching and sustaining a specified speed. Typically, a tire with a higher speed rating results in better handling. Speed ratings are determined via laboratory tests that simulate road performance at various speeds. Tires are assigned a single letter (such as H or V) to designate speed rating.

OE and OEM

OE means “Original Equipment” and refers to the tires included with a new vehicle at the time of purchase. The vehicle’s manufacturer selects these tires to provide the optimal performance based on the performance characteristics of the vehicle. “OEM” stands for “Original Equipment Manufacturer”.
