I am approaching 30k on the stock Grabbers, and they will need to be replaced before winter in MI. I found these Nitto Nomad Grapplers. They're marketed as and on-road all terrain for crossovers and small SUVs, but come in 275/60-20 116XL size. They seem like a relatively new tire, so not a lot...
Long story, but I'll pick up an off the lot Lightning on Thursday with a blue stock sticker. Same specs as everyone is seeing, Lariat SR, BlueCruise, rubber mats and spray in liner. A-plan price, no markup.
