I used blackcircles recently to buy some michelin energy e3b tyres (£153.16 for 4 using discount code), absolute bargain compared with anywhere else. The fitting service was excellent with the tyre fitter recommending which tyres be changed (I have 2 spare wheels) and pointing out one wheel was buckled demonstrating on the wheel balancing machine after he had fitted the new tyre to it. Superb service! He offered to swap the tyre from one good wheel over, so I accepted and there was no charge for this extra service. On the whole a good buying experience.
