Add vent holes when mounting your RC tyres with the FASTRAX tyre punch.
Your wheel/tyre build will need to have vent holes. These are often in the wheel but a popular alternative is to make the holes in the tyre, and this FASTRAX punch is the ideal tool.
Having the hole in the tyre will also help when running in wet conditions as it allows the water to exit through centrifugal force meaning it won’t saturate and damage the insert.
