Ok, not that it was a forgotten neccesity, but as i build my monster, up to this point haven't falied to cover this neccesity, but not sure how to handle it. Ive been lucky up to this point not to need to change a tire. Can a highlift jack succesfully and safely support the weight of a fully outfitted F550 to change a 44" tire. I mean i get the back end up and feel somewht secure in its ability, but what about the front end. just a couple of weeks ago the truck wouldnt start and had to have it towed to the Ford dealer. The tow truck was a F450 and when it lifted the front b/c he couldnt get under it from the back he started to bend his wheel lift. I mean it was kind of neat and i was proud of myself to watch his truck squat and my truck just sit there, i wasnt sure what was making the terrrible squeaking noise but i waws like i said neat. I digress, So back to my querry, what is the consensus?
