something i might add if i may, could be that i'm just gun shy now but be cautious when fooling with these especially the inside ones when your pulling the spacer off. i used to be a tire guy at a truck stop for 5 yrs. and had one of these blow up on us when we were removing it from the truck.pulled the spacer off and when my coworker reached in to pull it off all hell broke loose.he had 11 breaks all from the knees down some of them sticking through the skin.seems that the rims lip was cracked over half way around. i started letting the air out of the inside ones before i rermoved them. i started inspecting them all before i put them back together.and found quite a few cracked ones. so just be cautious and stay alert when you mess with these things.that was over 20 yrs. ago and the guy i worked with still wears an electronic device to dull the pain. as far as gettin the dayton wheels straight . the trick is to spin nuts just snug in a star pattern then start with one and tighten it and just go around in order. worked every time for me........dave
