Our 12-1/2 x 2.50 heavy-duty tire and tube set for all-terrain scooters is a great buy for anyone who needs this size rubber on their scooter. The 12-1/2" x 2.50" all-terrain tire can be used on a wide variety of electric scooters from many manufacturers, everything from Boreem to X-treme as a replacement for the more common 12-1/2" x 2-1/4" tires. So if your scooter takes 12-1/2" x 2-1/4" tires, but you want a knobbier, heavier duty tread, consider this great tire and tube combo.
