After seeing both in person, I changed my mind and decided to go with the 20x9 0 offset wheel instead of the 20x10 -19 offset I was planning on. I just liked the look of the 12.5 tire on the 20x9 wheel better and also the way it fit in the wheel well better. After seeing the bushwacker flares in person they just looked to bulky to me, and the streamline fenders with 20x9 wheel just looked sharper to me. Also the the 20x9 inch wheel just looks bigger to me, I guess because the spokes of the wheel were more visible because of the less offset but it just gives the illusion of a bigger wheel and taller setup to me....
Also, I know the Toyo MT is a great tire, but they are very heavy. A 35 in Toyo MT at 78-80 pounds weighs almost the same as the 37 tire that I decided on.
Anyway, just my 2 cents because I was the same wheel size situation.
