Tires for 80% daily driving - 10% towing - 10% off-roading

Hi Everyone,

What tires and size do you recommend for 80% daily driving - 10% towing - 10% off-roading in the Chicago area?

I have a 2019 TRD Sport CM with the following setup:
1) Bilstein 6112/5100 @ 1.9" in front and back
2) 1 CB shim on front driver side to get rid of the lean
3) CB +3 shackles
4) Firestone Air Bags

I have 20" and 18" Toyota wheels (8"x60mm offset) Can't decide which one to use for daily/tow vs off-road. I was thinking 18" for off-road and 20" for driving and towing. I was looking into 275/65R20 and the 285/75R18. I plan to install the RCI skids to prevent rubbing.
Would definitely appreciate your thoughts? Been scouring the forums but can't decide.

Should I just save one of the wheels for winter tires? 18 or 20?

Deciding between General Grabber ATX or Cooper Discoverer AT3 XLT or any other ones other than KO2s.

 

275-70-18 Cooper AT3 XLT

 

I don't have an input on the size, but consider the Nitto Ridge Grapplers. Very well mannered, look great, and I hear perform excellent offroad - but I'll likely never find out

 

I have the exact setup you do but with 18 inch SCS wheels so the offset is different. You want the Cooper AT3 XLT all day long. 60k warranty. Pounds lighter than the Nittos and other brands. Super smooth on the road and work well off-road also. I can’t speak about snow or ice though.
