Compatible Dirt Bike Brands and Models These tire and tube sets are compatible with dirt bikes, pit bikes, motocross bikes, and pocket bikes that have 10-inch rims on both front and rear wheels. You can use them to upgrade your 2.50-10/2.75-10, 2.75-10/2.75-10, or 2.50-10/2.50-10 bike tires. So, if you need universal fit 2.50-10” tire/tube and 2.75-10” tire/tube, AR-PRO offers you a front and rear set for less. Still undecided?
