Special Notes: When selecting new motorcycle tires, be sure they meet the requirements of your motorcycle and its expected usage. Please use our vehicle drop down selector at the top of this page to assist you in choosing a tire for your vehicle. Always refer to your owner’s manual for correct tire specifications for your vehicle. Size 4.00-18 Tire Construction Bias Load Rating 64 (617 lbs.)

Rim Size 18 Tube / Tubeless Tube Type Directional No SAFETY Inspect and check tire pressure often. This is the most important tire-maintenance function you can perform. Refer to your machine's documentation for proper maintenance. Always give tires a gentle "run-in" period of 100 miles to get the feel of new tires--this means they should not be subjected to maximum power, abrupt lean-over, hard cornering, etc. Always match the front and rear tires for optimal handling, safety and performance. Mixing radials, or mixing radials with bias or belted-bias tires, may adversely affect handling and stability. WARNING The charts and information on this page do not imply interchangeability. Consult your machine's manual to determine correct replacements, clearances, compatibility and stability, load-bearing capacity, speed rating, radial vs. non-radial, pattern and tread compound requirements, inflation recommendations and front-to-rear tire matching. Wrong selection can result in tire failure or loss of control with serious injury or death. The MT 43 Pro Trials Tire from Pirelli is a trials type tire with a great balance between performance, price, and a long tread life. The MT 43’s main feature is a unique tread pattern geometry that helps the tire find a good amount of grip on wet, dry, or hard technical terrain. It’s also DOT approved so getting from one trail to another on public streets won’t be a problem and your tire won’t get chewed up or worn out doing it. To create this resilience, the tire uses a reinforced bias ply construction that makes the tire deform less while still giving it a wide contact patch. This makes the Pirelli MT 43 Pro Trials Tire a solid choice for experienced technical riders wanting pure performance and other riders that want to experiment and see if a trials tire will work for them. Specs: For technical trail and trials-type riding Good performance on hard, wet, or dry terrain Great for indoor events Reinforced bias-ply carcass reduces deformation and maximizes footprint Unique tread pattern geometry complements construction and application DOT Compliant
