Ordered a set of 4 tyres on Black Friday which turned out to be not safe for my car which Costco staff didn't inform me until I turned up for an appointment. By that time I have already wasted my time to travel there, being turned down and missed all Black Friday deals. FYI the Goodyear tyres that I ordered were correct size, speed & load rating for my car. If you search for Costco UK reviews, their customer care is also utterly useless, they only respond to positive feedback basically ignore all negative feedback from what I can see. When I turned up for the appointment I was told by the staff member that these tyres are runflat which means not safe/suitable to be fitted on my car. I must point out that these tyres are actually recommended to me on Costco Website!!! I filed a complaint however the customer care basically denying all responsibility and insisted that it was my own responsibility to make sure the tyres are suitable. Overall a series of incidents has caused me to miss out on all Black Friday deals. Basically Costco was saying they only supply tyres but it is their customer's responsibility to make sure the tyres are correct / safe for their cars and will not compensate me. I regret that I wanted to save a bit of money and went for Costco to get these premium tyres. I should have read the internet reviews and went for a proper tyre shop.
