What worse, this isnt the first time roar has made a rule that makes an item we buy illegal. The Proline VTR is illegal under ROAR rules. Before 2009, there was no rules limiting truggy tires. Now that the VTR is out, there is a ruling that states the max inner bead diameter is 3.75 inches. The VTR inner bead diameter is 4.0, and is that big simply because they changed the way it mounts to the tire. If it had the traditional bead that the LPR, and AKA tires have, it would be legal. But Proline went a step further and made it like the buggy, and now is not ROAR legal.
