-20mm offset rims on 8 lug

[vardenafil]

i found some craigslist rims that look retro and will fit my truck. Doing research on here and other sites I found that the rims should be 0 offset. the rims i found are -20mm offset. i dont want my tires to stick out real far from the fenders. about how much will my tires stick out if i get 35x12.5 r16 tires or 35x10.5 r16 tires. if it sticks out minimal like an inch or so i will snag these rims up.
