6" lift w/factory wheels

I was wondering if anyone could post some pics of a titan with a 6" lift and factory rims with 35" tires. I have a fabtech lift and I was told by my dealership that I could not run 35's on factory wheels cause they will hit the spindle. I bought my truck new with the lift, rims and tires already installed with aftermarket 20's. I asked at the dealership if they have any factory wheels sitting around and thats when we got to talking about putting them on with 35's. They said cause of the lift it could not be done. Is this true?
