Just had a look on black circles, looks like its £5 cheaper on a tyre costing £155. Not sure that's a great deal?
Fwiw, the bridgewater kwick fit seem very good. Fast, reasonably priced and consistent. Only had tyres there mind, and only a full set or a change, not a pair.
Bathwick tyres are as cheap as I've found in the Bath / Bristol area, but fitting is sometimes a bit iffy (balancing out) They'll sell 2 winters. I'll be going to my local one in the morning for some new ones for the family car, but I'll be sure to take the dual carriage way home just I case there's a bit of vibration!
