The Scorpion MX32 Extra X motocross tires were designed with a wide range of use. These tires are strictly meant for off-road purposes and cannot be used on public roads. The Extra X front tires were designed with two key features, an arrow-like block layout and V-shaped tread blocks. The arrow-like layout make these tires beasts on the straightaways. The V-shpaed blocks allow for improved braking stability and superb cornering. The rears provide excellent traction on any terrain. Not to mention, they're reliable and can be used for miles of fun! If the track or trail conditions are unknown, the Extra X tires are the way to go with their ability to handle mid soft to mid hard terrains. So, if you're looking for less DNFs and more podium finishes, make the change and switch to Pirelli Scorpion tires.
