INCH-UP GUIDE

WHY INCH-UP AND LARGE WIDTH ARE NECESSARY

  • Excellent high speed endurance
  • Wide ground contact area improves safety during high speed driving
  • Improved braking power thanks to the increased wheel disc diameter

HOW TO CALCULATE WIDTH AND INCH-UP

  • When the Aspect Ratio is decreased by 5, the section width increases by 10. E.g.) 195/70R14 => 205/65R14 => 215/60R14 => 225/55R14
  • nch - up (in case of the same Section Width) In case of the Same Section Width, when the Aspect Ratio decreases by 5, one inch is added. E.g.) 205/65R14 => 205/60R15 => 205/55R16
