Spacer Thickness?

[fourx4forfun]

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.

unless you're going with really wide tires on stock rims, the minimum spacer will be more than enough due to the space needed to get the set of lug nuts on that hold on the spacer, and not stick out of the spacer and interfear with the outter rim. So you're looking at about 1.5" min.

I was told when I did mine to go with 2" spacers. This way you can always go bigger on the tires and with anything shorter you may have to trim the studs down to get them to fit.
