Car Tyres Online of driving on underperforming tyres? So was a friend of mine. He told me the stories of his vehicles that he drove for years with the same “meh” performance, and the shops were just never able to improve them. He also has tons of issues with tyre shops who push things that he didn't need or want. I guess this ends up being the fate of many folks in the past few decades. Sometimes repair shops could be mistaken about your needs and try to sell you things that aren't relevant to the problem or make money off you instead.
