How did they damage my wheels?
To make a long story short, I had 4 new tires installed at Discount Tire this past Saturday on my 2013 F150 with the chrome clad 20" factory wheels. Rained all day Sunday. Started cleaning my wheels on Monday and found chunks taken out of 3 of my wheels at the valve stem. I have an appraiser coming out and spoke with the manager about it. Of course he played dumb and didn't "know how they could have caused something like this." He brought out a valve installation tool he claims was used on it that is nylon coated and tried to play me for a fool by showing how it wouldn't touch the spot where the damage was. I informed him that was because the valve was seated- the tool most certainly would contact the area when the valve was in the unseated position. My original theory was that the square shouldered nylon coated tool he showed me wasn't square to the wheel and when they torqued it the chunk was removed. Upon further investigation today into valve stem insertion tools, I think my valves were installed with a standard Milton S449 type tool. This tool appears to be shaped to perfectly fit the gouge in my wheels. Any other theories?
2 had chunks removed like this picture, and a 3rd had been damaged on the inside of the valve stem hole, if that makes sense. The 4th was roughed up in the valve stem area, but he claims they only changed 3??? Regardless, they are the only ones that have ever installed tires and I can prove it. And it most definitely IS a tool mark.
