offset rims on 66 c10 lwb

[papaws66]

how much offset will fit on a 66 c10 without any mods? i'm looking at some 15x8's with -13 offset.
also, how wide of a tire can i put on that without any mods? don't want to change anything but the rims!

If you have 6 lugs; 6x5.5 is correct!

[papaws66]

yep, they're 6 lugs! i didn't want to take the hubcap off to measure.. too hard to get back on! thanks

I have 18x8.5 at 4.5" backspace and 18x9.5 rear at 4.5". 295/45/18

15x8 4 1/2 back space. rear tires i had 275-60-15. you have about a finger space between tire and bedside. this on a lowered fleetside

[papaws66]

so... i need positive backspacing for it to work good? honestly i have looked to see how much space i have with the originals.. thanks for the replies!

Ban you've got that wheel/tire combo down! I'm a steelie guy but those are awesome!

this is probably a dumb question, but the only way to find out is to ask... what's the difference in offset and backspacing?? thoroughly confused.. never had to buy any before! (also... google is confusing )

never mind.. i found a diagram that explained it good. feel pretty dumb now, cause if you think about it hard enough it makes good sense!

i'm thinking maybe these rims with some 275/65r15's on back
