Help me choose my wheels and tires

HI, I just bought a 2018 Off Road DCSB. Mag Gray. I do mostly highway and city driving little "off road" maybe trails forest service roads. I like the BF Goodrich KOs they look great but not sure the best size. Ive driven some tacomas with larger tires and some tend to wander side to side in the lanes. I can't have that. Any suggestions?

 

There are lots of threads already on this subject in the forum. I am currently looking into the same subject. I ran Goodyear Wranglers on my F-150, they were great for over the road and light trails. Dont remember the exact size.
