Jeep ZJ Wheel Size
 

I want to upgrade to Cooper Discoverer STT PRO 33s on my 1996 Jeep Grand Cherokee 4x4. My question is which wheel size should I upgrade to... 16s, 17s, 18s, 20s? My use is strictly highway/road transportation through deep snow and bad weather. In Advance, Thanks, Harry!

First of all inch-dimensional tires are only available in 15's, and 20's for the big trucks. I had 33X12.5/15s on my Chevy truck with 7 inch wide rims. Those are monster tires and running those on your jeep would require a lift and trimming.

I ran 225/75R15s on my 97 and that thing was a tank in snow.
