How did the siping work out on your tires?If you're going to play in the rocks, stay away from 2 ply sidewall tires. While I do like KO2's, DuraTracs, and similar tires for on-road and light off-roading, their sidewalls aren't as durable as others.
From your description of intended usage, my vote is for the Mickey Thompson Baja Boss AT. Their sidewalls are super strong, they're 3PMSF rated, and have very good off-road traction. I've seen other Jeepers do very well with them on the Rubicon and other rocky/hard trails.
For a daily driver, these tires make the most sense.
I've run Nitto Trail Grapplers and they have strong sidewalls, but I didn't like their traction or tread life. I currently have Nitto Ridge Grapplers on my truck and they're garbage. Poor traction, poor balancing, etc. I'll never own another set of Nittos.
I currently have MT Baja Boss MT's on the jeep and they're excellent......except in the snow/ice. I did add siping to the tread blocks, which helps a lot. Once these wear out, I will be getting the MT BB AT's.
I replied to your DM with a much longer answer. But the siping worked great. The added traction on wet/snow covered roads is similar to a good AT tire. In fact, it works better than some AT's I've had. They grip really well on the rocks. The biggest downside is the possibility of the lugs chunking when off roading, especially when in the rocks. None of mine suffered damage, but it can happen. If you want/need an MT but also need it to handle inclement weather, then siping is a cost effective mod. I think it was $15 or $20 per tire.How did the siping work out on your tires?
