These are sold in sets of 2 and PRINTED TO ORDER, you'll need two orders to complete a truck, these fit the Proline Baja Pro X tires on a wheel width up to 25mm. If you use wider wheels please order the Fatboy versions. 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.
