Hey you guys that are running 15" rims on you Rubi's what is the backspacing
on the wheel are you using and are you running any spacers?
Keep getting told it won't work but I see you guys with them on your Jeeps.

Thanks for your help.

 

15x8 ION 170's with 3.5" backspacing.

Thank You!

Do you think a 4" backspacing will work?
I just don't know much about backspacing.

Anyone else?

 

3.75" works. I believe 4" works but it would be better for someone else to confirm.

 

I'm curious if anyone has a good idea of what backspacing is not enough? The thing is the further you push the wheel out, the more the load changes on the wheel bearings, etc.

I've got 15x8 Cragar Soft 8's on the way (to the tire shop that is).
They have 4" BS.
I'll be putting 33x10.5 tires on em.

Anyone have thoughts on that from past experience, etc?

 

I ended up with 4" BS and had to grind the front calipers just a little to stop them from rubbing.
Hope this helps.

 

I had those exact wheels with 35x12.50x15 ProComp XTerrains, and had no clearance issues on mine.

I guess I won't answer since I don't have a Rubi...
