Thanks- they look promising (for a non-snow tire) but I'm worried there's not enough siping. That matters a lot in New England with wildly varying snow and ice conditions.
Ridge Grapplers = fine for snow, but not ice. I wouldn't recommend them for year round use. Hard to beat as a three season tire that has tougher sidewalls than DT or BFG without being a MT. I'd buy them again (315), but rely on studs for those four nasty months. YMMV
