Need to borrow 4 32" tires

Does anyone have 4 tires (preferably mounted on XJ rims) about 32" that I can borrow for about a week and 20-200 miles? Mine are dry rotted and I can't afford new ones right now but I need to get a smog check. I might have to get some registers set, so I might have to do some driving, but if not it should only be about 20 miles.
