My wheels and ires finally came in! Overall I'm happy with the combo - there's a couple little quirks that bug me but I think I can work out the worst of it.
These are Strada Offroad Monster M08 in 20x9 with +0 offset. I really like a touch of chrome on a white vehicle and they work well with the bumpers, grill, and side steps. The only thing I'm not crazy about is the Monster center cap logo...looks a little meh, I guess. I think I'm gonna just pick up some 65mm wheel center decals with gold bow tie logos and cover them up.
The tires are Hankook DynaPro ATMs in 275/55R20. The ride is maybe a touch stiffer due to the small sidewall, but it's not terrible. I chose these tires based on weight primarily as I wanted to limit the impact to my fuel economy - and I also got these with a bit of a discount, so that helped sway my decision a bit as well. I thought really hard about running wider tire and sitll may later, but I think it fits the truck well as is. I should add, there is no rubbing on either side at full lock at least in the driveway...time will tell if they rub while driving.
Now it need color matched handles and mirrors!
