These useful storage products are designed to prevent flat spots on your tyres when vehicles are not driven regularly or stored over winter. Manufactured from tough plastic, the rugged curved shape is designed to spread the vehicles’ weight over more of the tread, eliminating the flat spots on tyres. Flat spots that can take many miles to iron out when the vehicle is eventually driven. Storing the car on the tyre trainers will stop any flat spots forming which in turn will lengthen their life. Less bulging of the sidewall reduces the potential for cracks and eliminates the need to jack up a vehicle when putting it away for the winter months. For tyres over 205 profile we recommend slotting two tyre trainers together. The tyre trainer can also be used as a marker for parking a car in the correct position in a tight garage as corner holes allow it to be screwed in place.
