Just got round to replacing the rears on my C2 - after some time on the computer-ma-bob I found National Tyres and Autocare offered as good deal as anyone I'd heard of before..noting that they have their own website and other tyre providers use them as 'fitting partners'. To find other sources, I opened Yellow Pages only to find a code in the National Tyres and Autocare ad that gave 10% discount - and the 'starting price' was the same as on their website. As 'icing on the cake' I qualified for the company's tyre guarantee that means they will repair the tyre during its legal life for free, or give an allowance against a new tyre, depending on how much tread remains on the damaged one. The guarantee leaflet specified eight different manufacturers but not Bridgestone (the tyres I chose) - but that didn't seem a problem.
Hope this may save someone a few pounds!
