I used Nokian Hakkapeliitta's (studded) for my Eurovan's Colorado winter shoes. Great tires. That vehicle required tires with reinforced sidewalls, I think because of the skinny tall heavy combination, so I'm not sure if that is needed. But with FWD, the van was super sure footed. When it lived in Cali, the Eurovan with chains going to Tahoe was awful
I've pretty much accepted that the Metris is NOT going to be able to make it to many relatively tame off-road locations. It's an urban delivery/service van. I drove the Eurovan off-road in Colorado and Wyoming, extensively, but even with its great ground clearance, it wasn't an off-road vehicle. Almost killed my CU freshman son when he ovalized the rear shock mounting holes playing rally driver with my van on an unsupervised trip into Aspen from our lakeside camping. He was only partly guilty, as I think they must have been de-torqued to begin with.
I think I'll explore truck/delivery tires when the 'kooks go on my Metris
