Frequently Asked Questions

Q: What is the CT NA020990 tire and what equipment does it fit?
A: The CT NA020990 is an OEM rubber drive tire manufactured by Caterpillar for the Caterpillar 990 Wheel Loader. This is a heavy-duty off-road tire designed for mining, construction, and material handling applications requiring maximum traction and puncture resistance.

Q: What are the specifications of the CT NA020990 tire?
A: The CT NA020990 features a 41.25/70 tire size with bias construction and high ply rating for load capacity and durability. The tire includes reinforced dual sidewalls for puncture and tear protection and a heavy rim guard to protect the wheel rim from damage during operation. Multiple tread patterns are available depending on application.

Q: What does dual sidewall reinforcement provide?
A: Dual sidewall reinforcement strengthens the tire sidewalls against punctures, tears, and sidewall damage common in mining and construction environments. This construction extends tire life when operating on rocky terrain, sharp debris, or rough ground conditions typical of off-road material handling.

Q: What does the heavy rim guard on the CT NA020990 do?
A: The heavy rim guard protects the wheel rim from direct contact with rocks, debris, and rough ground. This protection prevents rim damage, curb rash, and bead separation that would otherwise require tire replacement. It is essential for off-road equipment operating in mining and heavy construction applications.

Q: What tread patterns are available for the CT NA020990?
A: The CT NA020990 is available in multiple tread patterns optimized for different conditions: deep treads for maximum off-road traction and mud evacuation, and other patterns for improved fuel efficiency on firmer surfaces. Select tread pattern based on your primary operating environment such as rocky terrain, mud, or mixed ground conditions.
