Bought a tyre and it kept losing air. Brought it back, they checked it and said the tyre was fine and that it was the alloy wheel was the issue. They gave me a leaftet for a local company who fixed alloy wheels. I went to another tyre dealer who checked it and said the wheel was fine, the tyre 'beading' ( ? ) hadn't been done properly by Kwikfit, so they went ahead and fixed it for me, no charge.
