Tires and Back spacing help

Sorry if this has been covered all ready.

I Have a set of M/T classic lock blacks 16x8 with 4" back spacing. I am trying to figure out what tire size will allow minimal to no trimming will work best. Due to the Backspacing I am not sure how much this will affect it. I was hoping for some 265/70 but I am a little worried about them rubbing to much. I will be running Rough Country 2" BB on a 2001 WJ (Daily drive)

any pics. on what and how much you did trim would be great
Thanks for your input.

Not sure about the backspacing, but I'm thinking you should go to a 4" lift in order to get those under there. I have a 4" lift and get occasional rubbing (lightly) on the bottom side of the front bumper. I haven't trimmed yet and don't really plan to.

You should be able to get a 3 inch lift with no trimming for those tires. The 2" BB will require some trimming of the front bumper. I think there is a thread going around with a chart that shows the various tire sizes and lifts. [/QUOTE]

I run a 265/75/16 with no trimming. However when I wheel I rubs when flexed.

I have a 3" IRO with Bilsteins. I would go 3" IRO or OME. It's only a couple hundred more than a budget boost with good shocks.

Just my 2 cents

I under stand the chart, But right now I am running 245/70 at stock height with zero trimming and rubbing. I would assume I could increase that a little bit with the 2" BB (right)? How much will the back spacing affect it? that's what I am more worried about.

My best guess is that the 4" BS on your 16x8 wheels will cause some additional issues (stock is 16x7 with ~ 6" of BS). On one hand, a wider tire (say 265) will clear your suspension components with no problem. On the other hand, the reduced BS will cause more clearance issues on your front bumper - the BS and wider wheel will amplify the problem, especially in reverse at full lock. Plan on trimming with a 2" BB, even if only increasing tire size to 245/75/16. In short, the BS and width of your choice of wheels will probably cause you to need to trim the bumper cover if you plan on bigger-than-stock tires.

I run my WJ with 265/70R17 with a 4" lift kit and they rub a little when I do an U turn and turning the steering wheel all the way, but is minor rubbing. Mine are BFG's all terrain.
