20" Cooper Discoverer A/T3 tires on a WK2?

Is anyone running with 20" Cooper Discoverer A/T3 tires on a WK2? If so, what is your tire size, is there any rubbing, is your suspension standard or Quadra-Lift or modified/lifted?

Cooper does not make the Discoverer A/T3 in 275/55. (Cooper Tire & Rubber Company - Discoverer A/T3™)

They do offer it in:
- 265/60-20 with an O.D. of 32.52"
- 285/55-20 with an O.D. of 32.36"
... and some other 20" sizes but the ODs are greater than 33".

It is my understanding that the max OD on a WK2 should be 32", is that about right? I am running Wrangler Duratracs in 275/55-20, and the OD is 31.9". They almost never rub. The only rubbing is with the QL at entry/exit height and at a full lock turn.

I'm interested if the Cooper Discoverer A/T3 can fit a WK2 with 20" wheels. I like the wheels and want to keep the 20s, and I'm interested in that tire.

That's a great tire. Had it on my 02 and loved it. I wish they had it in our stock size.

Re: 20" Cooper Discoverer A/T3 tires on a WK2?

I'm interested in the Cooper Zeon LTZ for my 14' summit but not sure they'll fit at 285/50/20. Width may be my issue, but I've heard nothing but good things about them. I don't want the 275/55 as the overall diameter is larger than the 285/50 and the 285/50 is wider so may have some issues.

I have read many times that the 285/50 will fit better than the 275/55. Only problem is there aren't nearly as many choices with the 285.
