What does 18x8j mean for wheel rims?
1 Answers
18x8j indicates that the wheel rim is 18 inches in diameter and requires matching 18-inch tires. The 8j denotes that the tire width is 8 inches, with a minimum recommended tire width of 225mm. It's preferable to use 235mm wide tires, with a maximum allowable width of 245mm. Unless absolutely necessary, it's not recommended for car owners to arbitrarily modify and enlarge their tires. Beyond enhancing subjective driving experience, the primary performance improvement is limited to high-speed stability. For everyday use, it only increases fuel consumption and reduces comfort. Wider tires do provide better cornering support, but this mainly benefits extreme cornering situations which are uncommon in daily driving. Additionally, wider tires can also reduce the car's acceleration speed.
