What size tires can be fitted on 18-inch rims?
1 Answers
18-inch rims can accommodate tires with a width of 7.5 inches, suitable for 225mm wide tires, and can also handle a maximum width of 235mm. Larger 18-inch rims with a width of up to 9 inches are suitable for 255mm wide tires, with a maximum of 265mm, which can significantly benefit the vehicle's mid-to-high range acceleration and braking performance. There are various ways to represent tire specifications, with four common types in the market: British, German, metric, and American systems. The German system is similar to the metric system, except that the tire width is expressed in millimeters, and the aspect ratio is added. The inner diameter of the tire is still measured in inches, followed by the load index and speed rating.
