Yes, the spinners are a joke, but you are serious about the bling 20s. Personally, I think they are as impractical as spinners. Seriously, run some 15" Black Rock crawlers- they are tough, they are cheap. If they bend, you can pound them out, or buy another for 30 bucks. I really don't see any function for any rim/tire combo bigger than a 15" off road other than the fact that they make a truck look like a confused street truck. The big rims are functional for on road because you get better side wall rigidity and better handling- so I can see them for a street truck. But isn't side wall flex good off road? I mean, I want as much as I can get that is why we air down.
If I had that kind of money to blow I would buy an atlas 4.0, a professionally built cage or a nice set of 15" trail ready bead locks. I think the ones on ricks and Mudwhores rig are as cool looking as it gets, plus they serve a purpose.
If you are that concerned about your truck looking bling you could get your truck painted with some metal chip purple paint- then your fenders would match (personally I think they look cool white).
Just my humble opinion. I am looking forward to seeing your portal conversion.
