In July of 2014; I purchased a new drivers side front tire for my 2004 Yukon. There were(2) people working in the service bay. It took them 50 minutes to replace(1) tire and they did that wrong. One of the guys spent at least 20 minutes complaining that he was not«Walmart Certified» and he had been repairing cars for over 20 years; the tire blew out 6 months later. LOCATION: Wal-Mart Supercenter — Tire & Lube Express 2001 N Central Ave, Marshfield, WI54449 Ph.(715) 486‑9440 On January 23, 2015 that same tire that I purchased in July of 2014 had a blowout on the expressway. My family and I were traveling from Wisconsin to Illinois. After contacting roadside assistance they put on our spare but closest location to purchase another tire was the Walmart in Plover, WI(store #1828). We were told that just the problem tire could not be replaced, but that all(4) tires had to be replaced because they were different sizes. I told them to replace all the tires and put the best tire in the spare rim. They said they could not do that because it was against Walmart policy. LOCATION: Walmart Supercenter — Tire & Lube Express 250 Crossroads Dr, Plover, WI54467 Ph.(715) 345‑7855 We continued our trip to Illinois, after stopping for gas we noticed the front driver side tire was low. I called the service center in Plover, WI and told them the tire was low. They said the tire regulation said it should be at 32 psi, I told them the instructions on the tire stated 51 psi. We drove a little further and noticed the tire was almost flat. We filled the tire to 42 psi and had to continue filling the tire every hour until we reached out destination. Basically we spent the next 3 hours nursing this brand new tire. The next day we told our Yukon to a local service center. After inspecting the tire(and the other 3 to be safe) they determined the cause of the problem was an improper bead seal on the rim and tire stem. This was performed at the Plover, WI location was the reason for the continue leaking tire. It was a $ 25.00 fix. Two incompetent Walmart locations.
