Here we have a Rover 75 or ZT alloy wheel and 225 45 18 ZR Pirelli P Zero tyre. It came off a delivery milage car so is virtually new with just slight storage marks that you will not notice when fitted to your car.
Its unlikely you will find another in this condition so grab a bargain while you can. ( the tyre would cost you this much if not more normally )
May allow something on you old wheel if you are picking up which will make it even cheaper.
We can send for £12 if you can't pick up
