My rims(Weld Cheyenne 6) are 17x8.5, Backspace is 4.5 and offset is -6. Wrapped with Mickey Ts MTZ 33x12.5. Went with 17s at the time for a break in price on tires. I really doubt I could go any much bigger.

 

Now I'm confused. The manufacturer part number says 0 offset. That's 4.5 x 2 = 9 wide or zero. Right? Wouldn't -12 be on a 9.5" wide wheel?
The part number is 3752936GBMF


Here's a link to some sizes available.

You sure you don't have +18? With them not rubbing and not sticking out significantly it seems you may have higher offset than 0. Either way, they are your wheels and look badass, and they don't rub, can't beat that.

 

Thats not the right calculation to figure out backspace though...you have to either measure the wheel or check whats stamped on the back...and i kinda agree that if they only stick out half an inch then you probably have like a +12 or like jerry says +18 offset....a +12 is a 5.5

 

I know its not. I was basing my numbers of the manufacturers wheel selection... I measured the front of the wheel to face of hub and got a rough measure of 4"... Would that leave about 5 to 5.5 of roughly estimated backspace? This would turn out to be a positive offset either way... I'm gonna pull the wheel next chance I get and measure...
Thanks for your input guys, I don't want be spouting disinformation about what fits and doesn't....... Good catch!

 

Ok 06f150, its a +12 offset.... You called it! Thanks again for bringing that to my attention.

 

hahaha..no problem...it looked similar to what i had plus i have heard and think from experience that theres no way to run a 35 with 4.5" BS (9" wheel). Its no biggie..I was just curious. Im not here to blow up anyones spot or make them feel stupid...i dont see the point in that anyways...Hey, atleast you now know your wheel specs. haha

 

Definitely can't run 4.5 backspace with just a level (u might can with a 33 on eiththe minor trimming but not a 35) I experienced that last weekend when installing my wheels before my body lift and was having to make VERY wide swings lol some off the road to keep from rubbing

To OP... please no chrome rockers lol... I would go with a chrome or black /machined rim might check into a Moto metal 951 they are good looking rims (im not a chrome guy but had chrome 951s on my dodge and loved em)

 

Damn it, now I'm confused. You have 20s correct and on that site they aren't offered in +12 that I see. I see the +18. What am I missing?
