I personally would not want a Load Range E tire on my TJ. They are just too stiff for a TJ and to really flex for seriously tough trails, they have to be aired MUCH further down than a more appropriate load rating would be. Not to mention they just make the road ride stiffer than it needs to be.
Personally, I'd change to a non-16" size wheel so your tire size choices won't be so limited. For that reason, I stick with 15" wheels which allows me to run the more apprpriate C load rating MT/R Kevlar.
