GUYS! please remember that going to a 20" wheel combo is going to be double, if not triple the weight per wheel. Braking distance IS INCREASED. Before ordering all the brake hardware, think about increasing the rotor diameter, which would also include a different caliper/spindle setup. I am all for the GO GO GO, but we also need to STOP STOP STOP.
I didn't think there was going to be that much of a difference from the 15" 165/50/15 combo I had until I went out to do this measuring. Holy cow was that wheel heavy. I am a school teacher who used to work at a few tire shops in my younger years. I equal the weight to about a split rim set up for a box truck. Maybe not quite that bad, but heavy enough.

I AM looking into getting a bigger brake combo for my rig.

Just keep the longer stopping distance in mind.
