I finally went and got my tires mounted, and I couldn’t be much happier.
Not only do they look awesome on the 80, but I’m amazed by how well they ride and how quiet they are. I’m not exactly shocked, since I had the exact same tires on my F250 right down to the size, and those were excellent right from the beginning.
For anybody with a stock 80 wondering if 285/75/16s will fit, I can confirm I have zero rubbing anywhere. Oh, and they’re cheaper than the KO2 in the stock size (275/70).
Next on the docket: brake pads, and painting the wheels/caps while I do that.
