I run mine to belts. The oem contis looked like slicks all the way across the rear, I drove, no lie, for 7k with them like that and i could never get them down to cord no matter what I did.

I personally hate anything continental. The oem tires sucked, the last set of takeoffs i put on my 240 were contis... they sucked harder. Maybe got 3-5k out of that set.
