Buying Guide

  • What terrain is the tire best suited for? Identify whether you ride mostly soft, intermediate, or hard terrain to choose the proper compound and tread depth.
  • Tube type or tubed/tubeless compatibility? Some tires listed are explicitly tube type; verify your rim setup before buying.
  • Should you prioritize grip or durability? Gummy compounds provide more bite but may wear faster on abrasive surfaces; harder compounds last longer but can reduce traction in loose soil.
  • How does the tire size affect handling? The 120/90×18 rear size offers a balance of traction and control for most 18-inch rims, but check your bike’s manual for compatible sizes.
  • Front and rear matching sets: Are you upgrading both tires? A matched front/rear set can improve stability and handling on rugged courses.
  • Sidewall design and stiffness: Reinforced side knobs support cornering under load, but excessive stiffness can affect ride feel on rough trails. Consider riding style and weight distribution.
