These are Currently meant for Bouncers but if your crawler meets the weight limit for the current versions they will crawl anything. They are sold in sets of 2 and PRINTED TO ORDER, you'll need two orders to complete a truck, these fit the 2.2 Proline Baja Pro X tires on a wheel width of up to 40mm wide! I use simple Overture 95a TPU, I highly recommend you set your truck on stands when not in use. If you do experience flat spots, they will go away once you drive a little just like a set of old bias ply super swampers do. DOES NOT COME WITH TIRE OR WHEEL!
