What was his bad experience. Don't leave us hanging.
Well since I don't know the guy, only read the post on another forum, i would take it with a grain of salt. The guy indicated that he was a 4wheel parts employee and took exception to people not buying from them, then wanting thier tires mouted and balanced by them. He claimed to always say thier team was not competent and to send them away, etc.
I found that Big-O lists themselves on Tire Rack as an installer. First time I have "ordered" tires, but I picked up new Toyo MTs, 315-75-16 for $225 each delivered to my door. I did not find a local source that was even close and I was not going to wait for the BFG KM2s that I wanted.
