Well, I talked to the local tire shop today, and found out that the Goodyear MTR's in this size are on national backorder with no estimated availability date. There are a few sets of tires around the country, but I would have to pay an additional $200 for shipping.
As I'm weighing my options, I'm beginning to think this is a blessing in disguise. I really don't need mud tires for my daily driver. I'm starting to lean towards the Goodyear Duratrac now. Benefits are: less expensive, lasts longer, still good offroad, and good looks. They are E load range, but the weight is actually a few pounds less than my current tires.
Anyone running the Duratracs in the 315/75R16 size have any comments? How do you like them? Do they ride stiff?
