Santa Cruz Slime Balls OG Slime Wheels

Yes, these are excellent for rough terrain. The 78A durometer is quite soft, which allows the wheels to absorb road vibration and roll over cracks and debris much more smoothly than harder street wheels.

At 66mm, these are larger than typical street wheels. You will likely need riser pads to prevent wheel bite—where the wheel touches the deck during a turn—and you might find them too bulky for technical flip tricks.

A center-bearing seat means the core is perfectly centered within the wheel. This creates a symmetrical profile that offers a very stable, predictable feel and allows you to flip the wheels over to ensure they wear down evenly over time.

Not particularly. Because they are soft (78A) and designed for grip and comfort, they are meant to stick to the pavement rather than slide. If you are looking to learn power slides, you would be better off with a harder wheel in the 95A to 101A range.

No, the set includes four wheels only. You will need to purchase a separate set of bearings to install them on your trucks.
