I had some tyres fitted locally where I live in Bedfordshire. I drove to see family in Norwich and was fed up with the vibration so visited Drayton Tyre and Battery Ltd where they balanced the wheels properly by putting weights on both sides of the rim, not just the inside. The old boy who was the boss seemed so pleased to have a Mini in, the younger lads seemed more bemused! Had the front wheel toe setting checked as well. Very reasonable prices too. Let me go in the workshop while they did the work which was good as you can't see a thing from the waiting room.
