I'm running the new MT Radial Pros, I'm having issues w/ hooking up but that might not be the tires fault. I had QTP's, MT et's (the real deal) and the pro's. I can't seem to get below a 1.60 60 foot. If I flash the convert instead of loading it up it blows the Pro's up. I'll let you know how they work after the cal-tracs.
