I did some research on wheels that will fit on my truck and I think this combination will work but I want ask you all.

Got a 2005 rcsb lower 4/6 want to put a 20x9.5 +20mm backspace with 255/55/20 tires. Will I have any issues on the front or rear.

Thanks

 

i have the exact same question. same year but 3/5 drop . i don't want any rubbing. i may drop a little lower so want the rear to tuck

 

my last 04 was 4.5" front 6.5 rear and my 255/55/20's was not happy! even with the rear fender lips rolled the side of the tire rubbed, in the front i hacked up the fenders and rolled the lips and they still rubbed a LOT i dropped down to a 45 series tire but dont remember the size but it was either a 28.5 or 29" tall tire and the front would still rub on a really good bump
