The 200x50 tire with street tread for the Razor A5 Air kick scooter is the rubber that you want when you put your A5 Air onto the concrete. The secret to this tire is its low-siped Street tread. Instead of a treadless slick or an aggressive knobby, the directional Street tread on this great little pneumatic tire provides the traction that you want on wet surfaces without the clunkiness of a dirt tire. As a directional tread tire, you should only mount it with the molded-on arrows facing forward, but you can use it on both the scooter's front or rear wheels.
