Any tire shop worthy of being called one will/would correct that error without having to raise a stink. But for the ones who try to slip it by as being a problem for the customer to correct--refuse to move the vehicle until they correct their screw-up. Usually if you threaten to lawyer-up, they will get it right. If they are unwilling to do anything, follow through on your threat. Then, after they have corrected their screw-up, file a report with the BBB. If they will do it once, you can bet they will do it again if they can get by with it. I'm not big on the lawyer thing, but sometimes you have to use dynamite to clear a clog!
