I had one of my tires flat, thats why i decided on taking it to this store because i couldnt find any nail or something like that in it...35 min after i got my car back, and once ive started driving it, i felt like there was something wrong with a tire again, so i stop by gas station to check the pressure in it... the tire which was fixed by the discount tires, had a pressure of 50 psi... wow, in Las Vegas heat it will probably blow out within next 15 min if i wouldnt check... Sales representative inside the store were extremely nice, but now I have doubts about professional skills of people who are installing tires there. I would think twice before getting new tires there now, ive learned the lesson if "free service"
