… until, that is, I returned to KalTire Saturday morning for a retorque.
When Kal Tire installed my the tires, they had massively overtorqued the machine screws holding the hub covers onto my custom rims. As a result, it was impossible to access the lug nuts. After 20 minutes of backbreaking effort, the technician and I finally managed to remove the screws on 3 of 4 wheels, and I had him retorque all but one wheel.

I ended up driving home and drilling out the final screw myself. Although though Kal Tire offered to do this for me, I shudder to think of the consequences had I allowed a drill-toting Kal Tire technician anywhere near my rims.
Even though Kal Tire’s incompetence cost me most of my Saturday and a machine screw, I’m sure glad I discovered this here in town, and not at the side of some road dealing with a flat!
