I had an issue with ONE of my tyres which Mercedes seemed incapable of solving and another brand name fitting service wanted to charge me over £300 for 4 new tyres and wheel alignment as well. Went to Just Tyres and they were so helpful. Even though they confirmed that 4 new tyres were needed, they came up with a reasonable price including wheel alignment and regular checks on my tyres to help them last longer. Stuart even let me watch the process, explaining what was happening. He said it probably wasn't the valve (Mercedes had charged £21 for that) but a bad sealing round the tyre which was causing it to deflate. I found Lee and Stuart to be very helpful and nice guys. Thank you. Caz x
