What is the maximum tire size that can fit on 18-inch rims?
1 Answers
Normally, 18-inch rims have a width of 7.5 inches, and the most suitable tire width is 225mm, with a maximum usable width of 235mm. More information about car tire sizes is as follows: 1. The specifications and parameters of car tires are expressed in millimeters for the section width and the percentage of the aspect ratio. This is followed by: tire type code, rim diameter (in inches), load index (code for permissible load capacity), and permissible speed code. 2. Rims and tires with larger widths are not suitable for civilian vehicles. This is because wider tires create significant rolling resistance, requiring the vehicle to have sufficient horsepower to drive normally.
