I had some 33" Radial TXR's gifted to me by the PO, and they were not good. The tread blocks were too big to do well in the slick stuff (snow/ice), and the voids were not wide enough to throw off mud particularly well either ... The large tread blocks didn't flex very well offroad either. All around I would never pay to own that design again. They were not good at anything but dry road, and even then they hummed as much as my KM2's do, lol.
I haven't really seen a tread design they offer that looks particularly interesting, and with the sidewall cord ripples I saw with mine I wouldn't be willing to take a gamble with anything else remotely close. To me they are a run of the mill brand.
