2-part replacement "treads" that go OVER the existing rubber treads on the Alphard Club Booster V2 wheels. There is a LEFT set and a RIGHT set. One half has PINS and the other half has HOLES.
You place the inside one over the wheel by squeezing it a bit, then push it onto the inside, then place the outside one on, and line up the pins, while making sure the "anti-slip buttons" on the inside of the new treads line up with one of the existing tread indentations.
Using a clamp, apply LocTite 406 TPU CA (super glue) or equivalent CA (CA MUST be TPU compatible) to each outer tread part where the pin is, clamp the two sides together, then move to the next pin and repeat. Do this for the entire wheel, using plenty of super glue. Repeat for other tire.
Installation instructions included with each set.
