These are sold in sets of 2 and PRINTED TO ORDER, you'll need two orders to complete a truck, you can mix and match easier this way. These fit the JConcepts 4.19 Megalithic, Landmines, Tusk, and Hold tires. If you need Proline inserts they are different. 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. Also consider a little E6000 glue to set the inserts where they need to be so there is no sliding in the wheel.
