Generally they are reasonably priced especially for standard tyres & are conveniently located, unfortunately this time round for the type of tyre I required they worked out as one of the most expensive but I cannot fault the service I have previously received.
It is very easy to use; enter reg on website (confirm tyre size matches what you have), select preferred tyre (range from low to high end), select preferred location & book your slot.
Additionally the booking slot, tyre disposal & fitting are all included in the price.
