An online search found Walmart had the best price on the tires I needed for my RV. I had only ordered from walmart 1 time a long time ago, so I decided to take a chance & ordered the tires. The online ordering was a snap, I choose to pick them up at the store so that they could install them at the same time. After 1 week I got a call saying my tires were ready for pick up. I went there & said I'd wanted to have them Installed on my trailer wheels I'd brought with me, he said no problem they should be ready in about an hour. I left to go shopping, about 3/4 of an hr. they called me & said they were done. I was very happy they took the initiative to change the old valve stems out & balanced the tires, as well, since I forgot to ask them to do that when I left them. All this for $18.00!! Very pleased with the experience & very convenient!!
