Save time and energy when replacing flat or punctured tyres with the B-G Racing Tyre Changing Ramp. Designed for use on twin axle trailers, the Tyre Changing Ramp simplifies the wheel changing process. Simply loosen the wheel nuts/bolts on the damaged wheel and drive the good wheel onto the Tyre Changing Ramp. The damaged wheel is then suspended off the ground allowing for work to be carried out safely and efficiently, before driving the trailer back off the ramp and re-tightening the nuts/bolts. No more messing around with jacks or makeshift shims, just throw one of these B-G Racing Tyre Changing Ramps in the back of the trailer. Sold individually.
