Here is what i can say. The associated Rival tire is Fsstastic! The Rival wheel not so much. They tend to crack. A good set of wheels would solve that. Also the Backflips were designed to withstand 6s power. So far, I haven't seen or heard of any cracks or breakages. On a side note. The tire design is basically a Proline Badland. Which is one of Proline's best tires. Hence the new MX38 and the new XMAXX tires. Which are both inspired by the Badland tread design. So the Backflip provides performance like a Badland would. It's also not a massive wheel and tire combo. The size is just right. For this size MT.

All in all the Backflips are a great durable, grippy and properly priced wheel and tire set.
