The configuration of the lug nuts on a Toyota Tundra’s wheels is a critical specification that dictates wheel compatibility. This configuration is described by two numbers: the number of studs or bolts and the diameter of the circle on which these studs are arranged. For example, a specification of 5×150 indicates five studs positioned on a circle with a diameter of 150 millimeters. This measurement is essential for ensuring that aftermarket wheels are securely mounted to the vehicle’s hub.
Understanding the precise wheel stud arrangement is paramount for maintaining vehicle safety and performance. Incorrect wheel fitment can lead to vibrations, premature bearing wear, and, in extreme cases, wheel detachment. Historically, this specification has evolved alongside vehicle design and weight to accommodate increasing payloads and towing capacities. The correct specification ensures proper load distribution and contributes to optimal handling characteristics.
