Tread width is the width of the tire’s treaded portion—the rubber that contacts the road—measured across the top of the tire from the outermost major groove on one side to the outermost major groove on the other. It isn’t the same as section width (overall width, sidewall to sidewall). Tread width influences dry/wet grip, steering feel, and noise, while section width and overall diameter drive most fitment decisions.
Tread width affects shoulder clearance at full steer and under compression, but section width, offset, and backspacing are the primary fitment drivers. Before you buy, review Wheel Offset Explained and Custom Wheel Backspacing. If you’re changing wheel width or offset, also confirm hub fit with Custom Wheel Hub Bore. Want a quick stance preview?

A wider tread doesn’t automatically mean higher capacity. Always match or exceed OE load index and speed rating. Maintain proper inflation to support the intended load and to keep the tread contact patch working as designed.
