please help

i bought a rustys 4.5 spring pack lift and i was wondering with some fender trimming will i be able to get 33s under it?

From one of our "stickies":

Lifts (tire fitting, backspacing, lift types)

What size tires can I fit on my Jeep?
There is no absolute due to variance in suspensions, but here are some general guidelines…

-- No trimming and no lift, factory wheels
Typically a stock rig can handle 29" tires, MAYBE 30"… 235's metric…

-- No trimming, 15x8" Tech1 w/4.75 backspacing --

With 2" lift = 29 to 30x9.50 tires
With 3" lift = 30x9.50 tires
With 4.5" lift = 31x10.50 tires

-- Minor trimming, 15x8" Tech1 w/4.75 backspacing --

With 2" lift = 30x9.50 tires
With 3" lift = 30x9.50 to 31x10.50 tires
With 4.5" lift = 31x10.50 to 32x11.50 tires
With 6" lift = 33x12.50 tires

In addition to these guidelines, year must be considered. Up to 96 the wheel wells were generally more "open"…97 and later have a tighter front wheel well and are more likely to experience rubbing. Of course, virtually any tire can be fit with enough trimming. Typically most XJ owners don't go much larger than 35" tires, and that's at a minimum of 6" of lift.
If your wheel backspacing is less than 4.75" (such as 3.75") expect to add at least an extra inch of lift.
Also, thinner tires will fit easier as well. (such as 33x10.50's)

That stickie doesn't know what's up... Sorry to say it, BUT...

I'm at 4.5" Rusty's with 33"x12.50" BFG MT KM's: Trimmed of course...

*why that^ pic has a white border idk... lol*

I mean c'mon, the entire subject of bumpstop-(s/ing) isn't even addressed. (at least in the snippet there^)

I don't know what kind of rubbing would occur with stock 'short arms', (I have the Clayton set up), but yeah, i rub the lugs when steering hard-over with only 4.50" backspacing.

Currently, I don't have ANY bumpstops.(BAD IDEA!) This has definitely limited what i can play in. I'll have them straightened out for Zuhwarrie next month though... (oct 19-21 form what i've heard)
