2017 GMC SRW 265/70 R18. We currently have Michelin LTX-AT2 tires that I am happy with (40k miles and just hit the wear bars) but for whatever reason these are on backorder everywhere. Local shop expects 6-8 weeks. Living in the snowbelt I need to replace soon. Any reccs? I can get Michelin defender LTX but not sure on these.
