i always carry a spare n jack ,always have a plug kit .....i liked the ,go to a different yard comment but sometimes thats not an option .......first yard i started going to was pretty good about keeping the steel area clean ,and would offer you a used tire if you got a flat there ,they kept after peaple dumping to keep sharp stuff in bins too ,.......second yard i started going to was horrible ,.....you had to take a broom just to pull in or else you left with a flat ,i stoped going there ,they sucked ....third yard and my current one is pretty decent ,but i've had a few flats .....they keep it clean the best they can ,and i'm always mindfull where i drive ,if i gotta pull in a scary looking section ,i get out and walk the ground before i pull in ,.....still get a flat every now and then ,but can't be avoided sometimes
