Not on my XJ, but on my TJ, yes. 32x10.50's. I'm on my second set, and will be going to the 36x12.5 soon if all goes as planned. First set was siped when new, and were no louder than the Wrangler GSA's they replaced until they wore past the siping, then I grooved and siped them again. Got @ 30k out of them, the GSA's made 40K and were literally smooth. The second set I'm still on, bought used and grooved and siped them. When I got the first set, I still had 3.07's, and even in low, first gear there were times when it would bog in thick mud and stop due to lack of power to keep the tires spinning. Running 4.10's now, still works the 4.0 pretty good when it gets deep. They clean really well as long as you can keep them turning. Overall excellent tire. Like I said, I'm getting the same tire, just bigger, shortly. One puncture in the tread, no sidewalls yet. I run 10-12 psi normally(offroad) and have gone as low as 6 on occasion. Radials typically are thought of not as strong, but the sidewalls are flexible, which allows lower pressure. I have sideloaded the tires till you can't see anything but wheel w/ the tire rolled under, sidewall on the ground, and not unseated a bead yet. Sorry to get so wordy.
