Understanding Your 2003 Toyota Tundra's Tire and Wheel Specifications
Wheel Size, Bolt Pattern, and Offset
For your 2003 Toyota Tundra, the wheel size, bolt pattern, and offset are crucial specifications. The wheel size refers to the diameter and width of the wheel, typically expressed in inches. The bolt pattern, also known as PCD (Pitch Circle Diameter), indicates the number and spacing of bolts that secure the wheel to the axle. The offset, measured in millimeters, determines how far the wheel's mounting surface extends from the vehicle's hub.

Tire Specifications
In addition to wheel specifications, understanding your 2003 Toyota Tundra's tire specifications is essential. These include:
Tire Size
Tire size is typically expressed in a format that includes the width, aspect ratio, and diameter. For example, a tire with a size of 265/70R16 indicates a tire with a width of 265 millimeters, an aspect ratio of 70% (meaning the height of the tire's sidewall is 70% of its width), and a diameter of 16 inches.
Tire Pressure
Correct tire pressure is vital for your Tundra's safety, handling, and fuel efficiency. The recommended tire pressure for your vehicle can be found in the owner's manual or on a sticker inside the driver's doorjamb.
Simplified Size for Tire Shopping
When shopping for tires, a simplified size can be used to narrow down your options. This simplified size typically includes only the width, aspect ratio, and diameter. For example, the simplified size of a 265/70R16 tire is 265/70-16.
