I know a member(s)were asking about tire to lift clearance on the 7000lb version of the QuickJack system. I have the 7000SLX model. Tire clearance is just fine if setup up in the right position.

My problem is with the extended length 7000TLX. Even with the lift pushed against the rear tire, it makes contact with the front tire as it rises.

I believe mine is the non-extended length. The extended length ones are recommended for trucks with long wheelbases from what I remember reading on QuickJack's website. With the 7000TL(the updated version of the 7000SLX) I believe you would be okay.
