Different Brands have Different Widths? (Tires)
Different Brands have Different Widths? (Tires) I have been looking at some pics lately. My friend's car has Pirelli P-Zero System tires, 295 is the width, and they are wide as hell. Some of the Nitto pics I've seen on here of 315's arent very wide, they even look smaller than the 295's. Am I just blind, or do different brands have different measuring techniques for their tires? Will the Nitto 555R 315 be wider than the Pirelli 295 P-Zero when placed side by side? Thanks.
Yes they do. Section Width, Tread Width as well as Overall Diameter all vary depending on the manufacturer.
For instance a 315/35/17 GForce T/a KD has a section width of 12.6" and a tread width of 10.4" while a Dunlop Sport SP 8000 of the same size has a section width of 13.2" and a tread width of 12.4".
There is a catch to this though, tires often feature tread designs that incorporate rounded shoulders and there is no industry standard pertaining to "how much" of the rounded shoulders should be included in the tread width measurement. Because of this, it is difficult to accurately compare the tread width differences of one tire brand to another. Tread width measurements are best used when comparing the various tire sizes or lines manufactured by a single tire manufacturer.
