Can anyone help with their experience on stock 20's please?

I'd like to run with a little bit bigger tyre on my stock 20's.
They currently run 275 60 R20 Cooper Discoverer HT+.
What's the max size I can run without rubbing on my torsion bar tweaked 03 that's leveled.
4x4 Hemi?
No one over here in the UK has a clue........so I'm checking in with my American cousins for their input.
Cheers.

34" diameter tires or smaller.

 

275/60/20= 10.8" wide and 33" tall
285/60/20 = 11.22" wide and 33.5" tall
295/60/20 = 11.6" wide and 33.9" tall
305/55/20 = 12" wide and 33.25" tall
305/60/20 = 12" wide and 34.4" tall

These are the only tires that you can fit without rubbing. Except for the last one you may have some rubbing at full turn unless you have a leveling kit or torsion bars cranked.
Hope that helps
