Long time customer . Dozens of sets of tires for company vehicle and personal. Went in for standard rotation and balance today and after 2.5 hours I was on my way. Went to vehicle to find a broken center cap for my wheel. Chalked it up to temperature and age. So as soon as I get time my tire light comes on, seems after all the training and suggestions about proper tire pressures their techs paid no attention. My 3/4 ton work truck was passed on to me with 40lb of pressure in A 80PSI TIRE!!!! today was ice and snow , discount tire is very lucky I didn't have an accident over this error.
From now on I will be shopping around after this neglect and lack of knowledge from their staff.
Corporate can feel free to contact me through email.
