35s on a JK with a 2.5" lift is the classic combination — street-clean, occasional trail rub at full flex; backspacing is the fix.
Heads up: Wheel backspacing ~4.5" (or spacers) keeps them off the control arms; expect occasional rub at full flex on the trail

37s on a JK want 3.5–4" of lift plus fender work — documented builds running less lift lean on flat fenders and accept trail rub.
Heads up: 3.5–4" of lift is the documented norm; flat fenders or trimming for flex clearance, and regearing is strongly advised
