Conclusion

The 305/55 R20 maintains major grooves clean, which helps to extend tire life by reducing “stone drilling.” It has increased the durability, stability, and mileage of the vehicle. Not only that, but the production method is environmentally friendly. This all-purpose SUV and light truck radial employs only low aromatic, refined oils. It also boasts a contemporary style and structure, as well as a unique base rubber composition for increased tread life.

The tread pattern’s coupling blocks improve steering responsiveness and wet-weather traction, while the sipes improve grip in wet or muddy situations. Off-road traction is ensured by aggressive tread block construction, which also reduces road noise.
