Aftermarket Tire Left/Right Set compatible with Radio Flyer Model 910 Tesla Model S (Made in USA) Our Tire was made specifically to fit this wheel size which is 8-3/4" x 2-3/4". We made it fit a bit more precise going down to the 100th of a mm for the snug fit. Guaranteed to improve traction and reduce the amount of Dad/Mom pushes to get unstuck from the yard! Includes a Left and Right Set of Tires for Rear or Front of the Vehicle. We recommend purchasing 2 sets to have all 4 Tires upgraded as seen in our photos!
