Hey Missy,
I just got the Kore chase system and put on 17x35 pro comp AT's on my stock wheels. I don't know if you'll have the same problem b/c I have the kit, but I do get a bit of rubbing on the control arms about 1/4 turn away from wheel lock. I've already gotten away from turing the tires that much, as you don't really need to unless you're parking. I think its because they have such a fat side wall, as from what I've heard the Toyo's won't rub at wheel lock. However, even though they rub, I'd never go with a different tire! If you want to see some pics with them on let me know and I'll send em to ya.
