I don't think the general public (and some on this board, sorry to say) knows much about driving and car dynamics. Just because you drive a 4x4 doesn't mean you can defy the laws of gravity or inertia. 4x4 only helps you start out, not grip the roads.
Dunlops have been getting beat down pretty hard on this forum and I think it's more the driver's fault than the tires. While they don't look like they'd do well off-road, they are pretty good tires for on-road. The storm before this last one was worse and I was on my way into NYC and the highways were covered in hard packed snow. There were guys in cars going ~5mph. I had no problems going ~25-35mph but when I reached curves, I slowed down to ~10-15mph. I didn't slip once. I also drove in VT when it dumped about 2 ft of snow. No problems with my Dunlops. It could be that my tires are new (just hit 5300 miles) but they worked fine in everything I drove thru so far. Most of the complaints are coming from guys that have more than 15k miles on their Dunlops. It could very well be that they start to suck as they get more miles on them. I guess time will tell.
I plan on doing some off-roading so that's one of the reasons I want new tires but I think I'll give these a shot at least once.
