What size tires can be fitted on 18-inch rims?

[DelLena]

18-inch rims can accommodate tires of various sizes, depending on the width of the rims in inches. Typically, 18-inch rims have a width of 7.5 inches, making 225mm wide tires the most suitable, with 235mm wide tires being the maximum. Here are the details: 1. Benefits: 18-inch rims can be as wide as 9 inches, suitable for 255mm wide tires, with a maximum of 265mm. These wider tires provide significant advantages in terms of mid-to-high range acceleration and braking performance. However, even wider rims and tires are not suitable for civilian vehicles. 2. Rim Replacement: If budget is not a concern, you can opt for rim replacement. Well-known lightweight rims are manufactured using forging technology. There is also another type made using cliff technology, which, although slightly less lightweight, can reduce the weight by at least 7kg compared to original rims of the same size. Lighter weight improves the car's initial acceleration, making daily driving more agile, and the higher toughness also makes them less prone to damage compared to original rims.
