check the bolt pattern, i know some jeep cherokees are 5x4.5 and some are 5x5.5( not sure on the years, his looks older so they should fit), best bet would be to ask the seller if can measure them for you. if the bolt pattens match, go for it. also ask about the offset on the rims. other then that it seems like a pretty good deal.
kinda long drive to london for some rims and tires though.... good luck!
