Recently had a chat with the dealership due to my nice new car kept losing pressure in one tyre. They tried to insist jsut a slow leak but I suggested a check up on the ramp and hey presto, a friendly bit of metal on the edge of the tread and tyre wall which they repaired but have yet to supply the same tread pattern tyre for. I wasn't prepared to fill the tyre with gunk. Like most modern cars - no spare tyre of any description. Getting the right replacement as in the tread (I prefer a matching set) seems to be beyond the dealership. I'm using them because I only pay for the tyre and not fitting. This being cheaper than going round the corner to National Tyres. I'd chosen this particular Audi dealership due to ease of access and proximity to the work place over the local one. Whoops.
