Goodyear G614 ,and Endurance Tires

Let me clear it up, I hope. Some people mentioned that Walmart could do the install of the Sailun tires. There is not one close to me that has tire service/mechanic work or whatever they call it. The one I used when I got tires on the van, is now closed. So off to Discount Tire I will go. Their parking lot is too tight for me to take the trailer to them so I am taking them off, 2 at a time and having them mounted and balanced. Then I will put them on my trailer myself. I have bought many tires from Discount over the years.
I was just mentioning Walmart and buying tires from them because in addition to the Sailuns, I got good tires and good service from them for a van. I bought a brand I never heard of, Douglas, but did do my research before I got them. Sorry for the confusion.
