Similar to what flash7210 did, a couple weeks ago I installed some Cooper Discoverer AT3 (245/75/16 - 120/116R) on my KJ CRD to replace the generico Kuhmo 225/70/16s that I put on a couple years ago when I first bought it.
There was quite a difference in the size & performance:
As you can probably see below, I did put a
slight 1" lift on the rig, when I upgraded the stock 110k-mile-old suspension, by installing Old Man Emu coil springs (927s on front & 948s on rear) & Bilstein shocks on the front and back in May 2014 (as well as replace the front upper and lower control arm assemblies, the ball joints and bushings, the rack and pinion, the rear control arm assembly and ball joints):
After I put on all the Cooper Discoverer AT3 (245/75/16 - 120/116R), there was a mild rub on front minimudflap facade at full turn/pinch. I just heatgunned the inside of the wheel-well and pushed/stretched it so the tire didn't make contact anymore, and I cut off that front 2"x4" front-minimudflap.
I like them a lot, and I can't wait to take them up to Tahoe for our next snowboarding trip.
