hey Guys,

Does anyone know if a MTZ in a 33x12.5 will hit the UCA's?

Here's the problem at this point... I have a set of pro comp series 97's... they hit the calipers...
The series 87's won't (so I'm told)...
Where the problem is at this point in the game is... do I exchange the 97's for 87's and take my chances that the tires won't hit the UCA's ... or do I just slap some wheel spacers behind the 97's?????

I've got a buddy who is very against the spacers... that's why I haven't got them yet... and have sent hrs looking for rims that fit ..and that I like.
But I'm getting to the point where something/anything is better then stock.

Any help would be great.
Thanks
AR

how wide are your 97 series? And yes, i believe it was either sbectold or air2air that had the 97 and found out they hit the calipers after he bought them. (i might be wrong on the name though) i am hoping you have 10"wide rims as 12.50 is pretty wide for an 8 inch rim.
Running that wide of a tire, you will either have to have a rim that has a small backspacing, or run a spacer, i would opt for the small backspacing, just one less thing to worry about on the vehicle. My 10.50's on 87 series 16x8 with 3.75" bs have plenty of room to the UCA and the body mount (which i had chopped but is not necessary)

I'm running 35x12.50x17 MTZ's. I got the tires before my lift and couldn't resist putting them on immediately. I did a body mount chop and they fit fine with my Moto Metal 951 rims. If I remember correctly, they rubbed a little at full turn. I now have 3.5" All-pro lift and have plenty of clearance. My FJ is a daily driver and I'm not happy with the street manners of the MTZ, so I'm about to get BFG KM2 35's.

Does your buddy know anything about spacers?

He needs to do some research. He's probably thinking of the bottom picture.

This is the good type of spacer:

Hopefully this data will help you, I believe you need spacers too.

My specifics: http://www.fjcruiserforums.com/foru...j-tire-size-selection-tool-8.html#post1011995

With a 3" lift and body mount chop, I am running Cooper Tire Discoverer STT 33x12.5x17R tires with 1.5" spacer (front only due to brake calipers) plus 4.5 " backspaing on ProComp 17x10" steel rims. I believe rim model is PCW97-7973. I'd like to take a little more off the corner of the chassis to have no rubbing when articulated.
