AVOID - MAJOR ALERT. Purchased 2 tyres from Asda Tyres for £500. The fitting etc all went well, however, 9 days later, the car went in for a service and Audi Cam flagged that the tyre tread depth was 5.5mm. Contacted Goodyear who advised that the tread depth for these new tyres should be 6.5mm. The car had been to the tyre fitters, then home and then Audi hence had only covered about 10-20 miles in total! Spoke to Asda tyres who requested pictures etc and found that the DOT numbers were also different i.e. the manufacturing dates were months apart and each tyre was from a different batch. Asda tyre's solution was that I buy 2 more tyres, pay the fitters to remove the recent ones and then send them back for inspection which could take several weeks. They couldn't exchange them! or naturally couldn't loan tyers or do anything else to help. I'm not sure if these were part worn or something or defects that Asda Tyres are buying but there is clearly something wrong. SCAM ALERT.
