I went to Walmart auto center to have new tires mounted. A yr ago I had 275/65R18 tires mounted that I bought and brought in on my 2014 Silverado 1500. I bought a new set of LT275/65R18 tires to have mounted. They would not mount them because they where not the orginal tire size that came on the truck. I will have the GM dealership in south haven ,MI mount and balance them, WalMart your tire centers suck totally, you have worthless staff and management not will care for the customer. I will never be back to Walmart again for anything period, you have lost a customer because of this .
