The tread pattern has been designed to provide excellent traction on all types of roads. Additionally, the tread has 5 ribs that improve stability and control. Zigzag sipes and grooves are responsible for even wear of the tread, helping to get rid of stones and pebbles. The tires are also beautiful in appearance thanks to the special ventilation technology.
Of course, for those who treat off-road driving as a casual adventure and prefer better traction, it is better to choose tires with lower rolling resistance and noise. The most optimal solution would, of course, be to have two sets of wheels, both for everyday use and for a specific occasion.
For people who want to ride the same set of tires all year round, these tires are the best fit. Usually, if the tire change is not followed by further modification of the car, we leave the wheels in the size recommended by the manufacturer, or only one size larger.
The size range includes models from 15 to 20 inches in the non-LT and LT ranges. You will also receive a 55,000-mile tread warranty.

The tires have standard tread wear indicators.
Thanks to the tread, a contact patch is formed, the grip of the wheel with the road is ensured, and most importantly, the tread removes water, mud, and snow slurry from under the wheel, ensuring its better contact with the road surface.
Ultimately, excessive tire wear reduces vehicle safety and can lead to accidents. Therefore, it is recommended to change tires much earlier than when the tread wears off to a minimum depth of 2/32 inches.
