33x10.5s on RE 4.5..how much trimming?

mounted on stock rims so stock backspacing...what kind of trimming am i looking at here? this pic has my 31s on the lift



doesnt seem like much but lets hear from some experience

should be close to zero trimming
maybe just trim-n-fold the sheetmetal, flares stay at same
location. Swamper 32x10.50 is wider tread than Swamper
33x10.50.

Possibly no trimming with the proper bump stops,mine are on 4.5"BS wheels and just barely rub.

I have 5" lift and I had to cut 1" of sheetmetal. Theres no way to run these tires without trimming the front unless you plan to use long bumpstops. The rear didn´t require any trimming but the tires rub sometimes.

Trimmed front with relocated stock flares:
