New Paint, Now to buy rims

[coltonk]

well truck is in the paint booth finally and had a bad problem with the paint and the "matte clear" mixing together and it didn't come out the way i wanted it to when it got painted it was really hot then a few hours later a storm came through so the guy who is painting it for me said he thinks it was the humidity. so he is in process of wet sanding it and seeing if it he can't fix it. Its driving me crazy. Im using John Deere Blitz black with 8:1:1 ratio just incase anybody was wondering.

But while thats getting fixed its time to get new wheels and tires. Im set on either Boss 338's (chrome) or Coys c-5 (black Chrome) I just need help on wheel sizes as well as tire sizes. the truck is lowered 2/4 and wanting to do a staggered look with 18x8 up front and 20x10 on back. Maybe somebody already has this set up and can show pics even with different rims. However i don't know which route to go with tire sizes. any suggestion and or opinions would be great help.


here is a pic of the truck in paint booth with the blitz black with the messed up matte clear, hoping to get that fixed by weekend. and here is the truck before any body work.
