The dimensions shown are average tire design values for tires measured on specified measuring rim widths.
Some tires may vary from this value by +/- 3% of the section height (affecting overall diameter), and +/- 4% of the section width.
Section width varies approximately 0.2" (5mm) for every 0.5" change in rim width.
Unique grooves and sipes combine with a modern compound to offer high performance at low temperatures.
