*Back Spacing*
« on: April 16, 2012, 09:04:21 PM »
I'm going to install some 33"x12.50x15 tires on my 2003 TJ.
Just put in a 4" Rough Country Lift.
I have 4 steel rims- 15x8 5 hole on 4.5 with 3.75 BS
Also have original aluminum Jeep rims- 15x8 5 hole on 4.5 with 5.50 BS
Which rims to mount the new tires on?
How much rubbing problems am I going to have if I mount them on
the original aluminum Jeep rims? Don't want to buy and run 4 spacers.
Thanks for any advice you have.  :-[

With4" of lift you should be fine with 3.75" BS. They might just rub at full lock on full compression with the sway bar unhooked.

They should be fine, full lock or not.

That shouldn't be hard to find one.  Now finding five on the other hand, ask me how I know.

FYI they are about $70-$80 at modern for d windows.
