Thanks all for your input, I really appreciate it!
My Taco is a 4x4 standard and I am running 90% tread Bridgestone Blizzaks in the winter so I am not too worried about snow and ice performance. I have some old Goodyear Wranglers on the truck right now... balanced, plenty of tread life left and no cupping (as far as I can tell) but I was advised by a mechanic that I should run something less aggressive because the "rough tread on the wrangler A/T adventure is hard on the suspension" after he noticed my front & rear struts/shocks need replacing. In my opinion they are not very rough and it sounded like a sales pitch for new tires, I am fairly mechanically inclined and will be replacing the struts/shocks myself (easy on a gen 1 taco) and upon closer inspection the struts/shocks are OEM Toyota struts that the previous owner just never bothered to replace.
However, that being said, I am not opposed to replacing them if its a bit better on gas/quieter ride and I would be interested to hear what everyone thinks about running an A/T tire with newer technology vs a smoother highway tire like a Michelin defender or something?
