Not to pi*s in your cornflakes here, but if Discount Tire told me the sky was blue, I'd have to go outside to check. These are the same people who tried to remove my wheel locks with an impact, breaking my key, then beat a socket on and still couldn't get the wheels off, all the while never telling me about any of this. To add insult to injury, they flat out refused to compensate me in any way for this, until I called the corporate office on my cell phone, directly in front of the manager. The only thing I got out of that was a new set of wheel locks, no discount for having to come back a second day for them to finish the job that they f'ed up on the first time. I ended up having to chisel my studs off and replace them. They'll never touch my car again.
