I have never had problems with Discount and non stock or race tires. They always ask me what my 275 pro drag radials are going on and I tell them my 68 Barracuda. They have my Barracuda on file for tire warranty on the front but the car has never been there I always carry them in. I did drive it up there to drop of my drag radials for balance a few weeks ago. They always ask about it when I do so I finally let them see it after a few years.

My Jeep also has much larger than stock tires and they rotate and balance with no questions.
