Does Wm do free mount and balance? - that is a big cost factor.
On a car sale $45/tire is cheap enough.
How much can you milk a stone?
It's not free, but their price for the mount and balance is very good. The best part is that they use proper torque and don't zip the air gun on them! However, you may have to wait a few hours.
Also, WM incluces free lifetime balance and rotation, including the flip/remount for directional tires.
