Dang. There's really no good selections of rims in a 15.

 

Not sure how these older trucks are, but -44 offset (which is about as negative as you can get on a normal wheel) on a 10" wide wheel would make them rub like a SOB on a 97+. Highly negative offset like push the wheel out way too much in the other direction. -12 on 20x10s is even too much for a leveled 4x4 2004+ and 33" without rubbing a little bit. -12 to +18 is the range I would stay in on a 97+.

20x14 with -44 offset are what you see on the trucks with big lifts and the wheels sticking way out.

 

These old trucks have radius arms and that's what they will rub on. You have to get a negative offset on these

 

you could always run a 1-2" spacer.
I know people say they are bad news, but if you dont cheap out on them, and torque them down then recheck the torque after so many miles I have faith in them. run some thread locker on the inside bolts.
Hell the dually guys have been running spacer/adapters so they can run 22.5 semi wheels for a while now, and I've seen them haul some massive loads down the highway with them.

 

Yeah I was going to say, a positive offset on these you would not even be able to steer with an oversized tire!

 

I'm not opposed to a 1 inch spacer. But idk about a 2

 

PS i beat you all with my -88 offset lol

 

IRK stock wheels are 15x8 with a backspace of 4.5" and a +1mm offset.

 

So say a 17x9 with 33x12.50 tires. The rims have a -12mm offset. Would I get by with that or would I still rub?

 

Agree with this. But if you know you aren't going to re-torque them consistently, I wouldn't. You have to get ones that are around 2" so that they have new studs pressed in in addition to full use of the stock studs. The thinner ones require trimming the stock studs to fit the adapters - which I consider a big no-no.

****, that's right on your front ends. Good God -88?
