So I got this rig used and it already had these bumpers on it. I like them but I want to add a spare tire carrier to it. Anyone got any idea what brand of bumper this is and where i could find the spare tire carrier?

 

That's an original jeep bumper that could be ordered from the dealer years ago. I -think- you can use the Mopar or AEV tire carrier but your safe bet (and practical) would be go with the Teraflex or MorRyde tire carrier. They add the tire carrier but also freshen up your tailgate and give you a spot to mount accessories. Avoid the temptation of the smittybilt knock off carriers.
