Thats a good point about the tire age...I heard about that too......I am about to pull the trigger and just buy the BFGs new.......kinda need to be able to trust the tires !! Adding more to the PS G-Box, my original one seems to be getting like me...old, loose and making noise any time it moves....I may look at the re-man option, maybe using a Junkyard Durango part as the core swap.....kinda covers all the bases,,,,,,,the AGR pump would be cool if I didnt already need to replace the G-Box......thanks again ALL!
