Is there a big difference with 17x9 vs 17x8.5 0mm wheels

Hey everyone i don’t know if anyone has asked this yet but my friends have been telling me that i can run a 17x9 0mm offset wheel would fit exactly the same way if i would run a 17x8.5 0mm wheels with 275/70’s ? Does anyone know if this is true or how much of a difference it would be ? If you could please post pictures of the differences if any it would be much appreciated !

 

No, it won't fit "exactly the same", it's a half inch wider... But it will be very similar. Here's a diagram that shows the difference:

 

The center point would be the same on the tire (0 offset) but on the 17x9 you have more backspacing and slightly more wheel poke.

With 275/70 you could go with a more positive offset like +4, +10, or even +15 probably. The more positive offset, the more cab mount clearance you will have when turning the wheel. You just need to make sure you will clear the UCAs with that wide of a tire and not too much backspacing that you will hit the spindle.

 

Thank you guys for the clarification, i put on my friends 17x8.5 0mm with 275/70’s on it and had no issues clearing it with the 2inch lift. Would it be very close result if i did it on 17x9 0mm ? I am a big fan of the fact his wheels were not rubbing at all but i am trying to run the Sww Dakars that only come in 17x9. Do you guys think it would work the same if not close to it ?

 

The majority of the 17x9's I've seen all have a substantial negative offset (-25, -38). Stick with the 17x8.5 zero offset to avoid issues.

If you prefer the look of a negative offset wheel you're going to have to cut and modify your truck to make them work.

Did you cycle the suspension and check for clearance the entire scrub radius? 17x9 with 0 offset is 5" backspacing. That will work fine. Personally I would go with a more positive offset wheel, but as long as you check clearances and it works 0 will be fine.
