What does 101w on a tire represent?
1 Answers
Tire sidewall markings like 101w indicate the tire's load index, where 'w' denotes the speed rating. The number 101 signifies that the tire can bear a maximum load of 825 kilograms, while 'w' represents a maximum speed capability of 270 kilometers per hour. Many passenger car tires display 91v markings – here, 91 is the load index (615 kg capacity) and 'v' the speed rating (240 km/h), which is the most common specification for family vehicles. Tire sidewalls display extensive information including production date, tire size (e.g., 205/55R16 indicating 205mm width, 55% aspect ratio, and 16-inch rim compatibility), tread pattern type, and recommended inflation pressure.
