I just got some 305/70/17 Toyo AT3's on my 17X9 +20 wheels a week ago. Also have a 2'5" coilover level. Replaced KO2's, 315/70/17. LRE, and don't seem much stiffer than the LRC KO2's. 40#F, 38#R. Seem about the same noise, handle similar. Look like they'll be better in snow than the KO2's that I always felt were only adequate at best. Winter will be the deciding factor as to how I like them, a few more months, I hope.
Toyo AT3's awesome tire, aggressive tread pattern for off-road adventures, but very quiet on the pavement IMHO! I have ran Toyo AT's on my last 4 F150 trucks and they have been bullet proof! The new AT3's are even better than the older AT2''s more aggressive but just as quiet on the pavement.
Couldn't be happier with the 295/60R20 Toyo AT3's with 2" level kit on stock 20's with my 2021 powerboost with no rubbing or trimming required. The stance and tire combo in my opinion is money.
I'm liking mine so far. Today we got some pretty heavy rains, and big thing I noticed, they felt better than the KO2's when leaving a stop. I was always aware of accelerating and thought of tire spin everytime, not with these ATIII's though, I even was a bit harder on the fuel. These things have passed all my desires, except for snow.
