The studs for the four wheels on my '99 TJ are 1/2" x 20.... but what about the spare tire studs? I recently bought new tires and was going to put the spare on the back, but the new wheel lugs would not spin on the studs. The tire shop left the spare off because it wouldn't fit (I needed to buy a spacer), and I bought all new wheel lugs to replace the old ones, so they tossed all the old ones away (so I didn't have a way of looking at the old ones to see what size they were).
Are the spare studs different than the regular tires?
