Offroad class trucks mud tires

I honestly don't know why trucks like the 310e, Royal 114sd, fleetstar, white western, and all of the trucks which use the UOD tire set don't have access to the JAT MMD mud tires. They're not necessarily ​better​​​​​​​​​​​ than the UOD tires. Just slightly more skewed toward mud performance at the cost of general performance. They're perfectly balanced tires for all of those trucks.
