My three biggest concerns for any tire installer (Walmart or any other well know tire installer) are:
1. Protect my rims from getting scratched/chipped when they remove install the wheels.
I had my tires rotated at the dealer and I expressed to the service manager that I was concern of the impact wrench causing swirl scratches in the lug opening (has happen to me in the past with other cars. After a while the clear coat peals from those locations). Sure enough, I found one swirl in a lug after they rotated my tires. Overall, It appeared that they took extra precautions - so I didn't complain. In the future (tire rotations) I will tape them up to prevent scratches.
2. Protect my rims from getting scratched/chipped when they remove install the tires.
Again, in the past I have been burnt on this. Even recently with my wife's minivan. The tech takes off the wheels and places them (along with the center caps) on the garage floor facing down (I mean, WTF!). This was at NTB, a well known tire retailer.
Taking off the tire with the wrong equipment can lead to scratched rims on outer edged, as well. Down the road, again, this will result in peeling clear coat. I believe they need to remove old tire from inner side of rim.
3. Proper high speed balance of tire.
The MO rims require weight that are glued into the inner portions of the rim (not the back side). You don't want some rookie to use counter weights on the backside of your rims. I'm not sure if this is even possible on the MO rims. The last thing you want is for them to give you a poor balance job and have vibration on the highway. I purchased new tires at Sears for a previous vehicle and had to go to Sears three times to get my tires properly balanced. Each time the tech. would say that the previous person who balanced did a not do a good job. Note: Sears and NTB are both owned by Sears. Yes, I finally figured out the connection too.
Anyway, I would suggest that you bring up all three of these concerns with the service manager. Have him look over the rims with you so you can both agree on the condition of the rims prior to them doing work (even take pictures and show him that you have documented their condition). Explain to him that you will not be happy if your rims are damaged and will seek replacements if necessary.
Good Luck.
