just put new set of 265 75 16 cooper at3s on 1999 2500 nice tires I noticed when the tires came off there was a small spacer on the passenger front maybe 1/8 inch thick and not on drivers side maybe previous owner lost 1 when he changed tires I left it on do you think I should take it off or get another one there seems to be no difference in the ride do they come with spacers on 1999?
