90/90-21 Metzeler Karoo Street

The tread design of  the KAROO™ Street  is delivered from the disruptive layout of the KAROO™ 3 and its uniquely shaped knobs with the precise objective to provide great on-road performance, wear regularity and a high level of stability combined with a cross-country appeal.
Extra-large central blocks create a wide and solid contact patch which ensures high speed stability on-road.
When riding off-road, the V-shaped knob layout with its multiple operating edges of blocks ensure acceleration, traction and braking grip; on-road, the multi-pitch knob layout is able to reduce contact vibrations, and it contributes to maximize wear uniformity and deliver effective mileage. 
Longitudinal grooves in the middle of the central blocks provide water evacuation and self-cleaning ability form dirt.
Wide transversal grooves contribute to make central blocks to dig the soil, providing off-road traction especially on dirt and hard-packed clay soils.
The variable shape of the block, together with their V-shaped layout ensures multiple operating edges that enhance off-road traction.
Big lateral blocks ensure a large contact patch when leaning, providing cornering grip and stability even at high speed.
