Struts/Shocks: Best Option

Feedback would be greatly appreciated!

Having trouble deciding on the strut/shock option for my 2014 Prerunner SR5 2WD 2.7L DCSB.

Currently all stock on Michelin LTX M/S2 245/75/16. The daily drive is fine; however, when I go off-road I am knocked around pretty good on rutted, washboard roads.

I have come up with some options to improve my off-road experience while maintaining the quality of my daily drive (at least I think I have).

What would be considered the best option:

1. Keep stock suspension and add All-Terrain Tires.

2. Bilstein 5100’s front/rear reuse OEM Coils front set at .00. (new AT’s).

3. Bilstein 5100’s front/rear reuse OEM Coils front set at .85 (new AT’s).

4. Bilstein 5100’s front/rear with OME 883 Coils front set at .00. (new AT’s).

Option 3 & 4 would provide approx. 1 inch and 1.5 inch of a lift. Which I understand results in a firmer ride. Would it be advantageous to level the vehicle and up-size tires to lighter weight P Rated AT’s (265/70/16 or 265/70/16) or keep the stock tire size.

Thank you!
