i got an offer to buy some 20" giovanni rims with tires for $500. i know 20's are gonna be huge for my truck i was jus wondering about the fitment issue and what all i'd have to cut outta the way and whatnot. right now all i have on my truck is a 4" drop in the back and lowered torsions. let me know if they'll fit and if i have to cut anything. thanks guys.
