A selection of aftermarket tyre valve caps and dust caps for Mini Coopers and classic Cooper cars. We have valve caps to suit all Cooper models, wheel styles and budgets. As well as adding aesthetic appeal to your wheels, the main purpose of a valve cap is to protect the tyre valve itself from dust, dirt and moisture ingress, as well as preventing a loss of tyre pressure. These valve caps are also often referred to as Cooper dust caps or Cooper valve stem caps.
