How to Read Tire Model Numbers?
1 Answers
Tire model numbers can generally be found on the sidewall of the tire. Here is a relevant introduction: 1. For example, 225/50R17-98H, where 225 represents the tread width in mm; 50 is the aspect ratio, with 50 indicating 50%. Most passenger car tires have an aspect ratio between 30% and 80%, and under normal circumstances, the aspect ratio of standard car tires is generally greater than 75%. 2. R stands for radial construction, 17 is the rim diameter in inches; 98 refers to the load index, with each tire supporting 750kg. H indicates the speed rating, with a maximum speed of 210km/h. In general, it is best for car owners to directly choose replacement tires with the same size data as the original factory specifications. The original factory size is the tire model that the manufacturer has verified through design to be the most compatible with the vehicle's powertrain, so it is advisable to avoid altering the tire size.
