ok guys, from some help in the regular forum finding out that when i get my new tires will need a spacer due to the sidewalls proly rubbing, how do you figure out which thickness to get? in researching tires, the ones that supposed to have do not have as good of a load rating yes they are 10 ply E, but 215 and 235's do not have the load ratings of the 285's and prior owner has 265's on it now but they are bout half gone so already planning ahead. will go w the 265 or 285's, do i need to worry about needing a spacer on the 265's? someone was saying needed to keep them more aired up so not worry bout the flex but makes the ride harsher, sorry, this dually not 4x4 rides like a town car compared to my old 250 diesel 4x4, now that was rough. so if just keeping more air in them to keep from rubbing, not an issue.
