so its about time that i get new tires for my xj, the tires i currently have on the xj have about 80,000 miles on them and are well used.  I know a guy who has a set of 235-75R15 tires that i can get for cheap but he used them on a cherokee with a 2" lift on it.  Will these tires fit on my xj with no lift??

all help will be greatly apreciated
