1. Introducció
This manual provides essential information for the safe and effective use of your Mastercraft Courser Mxt LT305/55R20 E 121 Q Tire. Please read it thoroughly before installation and use.
The Mastercraft Courser MXT is engineered as a mud terrain tire, featuring an aggressive tread design, functional side biter shoulders, and robust 2-ply carcass construction. This design ensures durable and dependable off-road traction. Its wide-groove pattern effectively clears mud, dirt, and debris, maximizing grip. The “zig zag” shape of the center channel enhances off-road traction while maintaining good on-road contact for stability and handling. Full-depth siping improves wet traction by providing biting edges on wet surfaces.
2. Característiques clau
- Large Surface Area Tread Blocks: Designed to provide increased grip on both on-road and off-road surfaces.
- Aggressive Upper Sidewall Design: Features deep “side biter” elements to enhance off-road traction and improve sidewall abrasion resistance.
- Angled Shoulder Scallops: These scallops contribute to mud traction by creating a “mud-scoop” effect, aiding in self-cleaning.
- Proven 2-Ply Carcass Construction: The MXT carcass design utilizes established technology known for its durability and performance.
- Stone Ejector Ribs: Integrated ribs at the base of the grooves help prevent stone capture and drilling, protecting the tire casing.

- Under-inflation or over-inflation can lead to premature wear and unsafe driving conditions.
5.2. Tire Rotation
Rotate tires every 5,000 to 7,500 miles (8,000 to 12,000 km) to promote even wear and maximize tread life. Consult your vehicle's owner's manual for the recommended rotation pattern.
5.3. Tread Depth
Regularly inspect tread depth using a tread depth gauge or the built-in tread wear indicators. The original tread depth is 19.5 32nds. Replace tires when tread depth reaches 2/32 inch (1.6 mm).
5.4. Neteja
