There have been numerous reports of a big, bad tire coming out by Pro-Line. It’s BIG. It’s bad. It’s the largest diameter tire Pro-Line has ever produced for Monster Trucks. Introducing the 7” diameter 40 Series Moab XL tire. The 40 Series Moab XL tire takes your monster truck to the next level by increasing overall ground clearance for more extreme rock climbing, stair climbing, hill climbing and everything in-between. It boasts a narrower carcass than standard 40 Series tires to reduce weight and allow for greater sidewall flex, thus increasing climbing traction. Because of the narrow carcass, it utilizes a specialty width 40 Series wheel – the 40 Series Cheyenne Bead-Loc. Includes: Two Proline Moab Tires with Foam Inserts
