FAQs
Is this tyre suitable for road use?
No, the Cougar D991 is specifically designed as a motocross (MX) tyre for off-road use only. It is not DOT-approved or suitable for prolonged road riding.
Can I use this tyre without an inner tube?
No, this tyre is designed and manufactured for use with an inner tube only. It is not compatible with tubeless systems.
What kind of terrain is this tyre best suited for?
This is an all-purpose MX tyre, offering good performance on a variety of off-road terrains including dirt, loam, and mixed conditions. It provides a balance of drive and corner grip.
How do I determine the correct tyre pressure?
Recommended tyre pressure depends on the riding conditions, rider weight, and motorcycle. Consult your motorcycle's manual or an experienced mechanic for specific guidance. Generally, lower pressures offer more grip in soft terrain, while higher pressures are better for hard-packed surfaces.
What is the size 110/90-19 referring to?
110 refers to the tyre's width in millimeters. 90 refers to the aspect ratio (the tyre's height is 90% of its width). 19 refers to the diameter of the wheel rim in inches.
How often should I check my tyre pressure?
It is recommended to check your tyre pressure before every ride to ensure optimal performance and safety.
Troubleshooting
Tyre won't seat properly on the rim
Ensure the inner tube is not pinched between the tyre bead and the rim. Slightly deflate the tube and re-seat the tyre bead, working evenly around the wheel.
Premature wear on tread blocks
Check for aggressive riding styles on hard surfaces or incorrect tyre pressures. Adjust pressure and riding technique as needed. Ensure the tyre is compatible with the terrain.
Loss of grip in corners
Verify tyre pressure is appropriate for the terrain. Ensure no debris is stuck in the tread pattern. Consider if the terrain is beyond the tyre's optimal performance range.
