Ditch your factory spare tire cover and flip that spare around.  Are you running bigger tires? Then get a full size on the back of your G.  Our 1-off Spare tire kits are laser cut and tig welded to insure the strongest mount possible.  We have taken the time to test the mount with up to a 42" tire mounted on it both on and off road.  Installation can be done in a little as 15min at home.
