I go Blackcircles. You order online and choose the garage to get them fitted. There is always one near you. Two front tyres from Blackcircles last year were about the same price as one from the local Kwik Fit, when I had to replace one of the back in a hurry after pothole damage.
A couple of years ago I bought two new tyres. At the end of the week the car was written off when some muppet drove through the lane of traffic on the right and piled straight into the driver's side of my car. His name was Courtney. Never come across a bloke called Courtney before.
And another car story. When the Tories win the election in a few weeks time it will probably be my fault. 1987 Blue car, Tory win; 1992, Blue car; 1997 Red car, Labour win; 2001, Red car; 2005, Red car; 2010 Blue car, Tory win; 2015, Blue car. 2017, Blue car (Skoda say it is actually grey but it is a distinctly bluish shade of grey).
