I'm contemplating upgrading to 16 inch wheels as well. Believe it or not, I had a steel wheel start leaking at the bead transition on our last trip.
Does anyone have a diameter measurement of the new 16 inch Sendels with the Michelin LTX M/S LT 225/75 R 16 Load Range E installed and inflated? I just want to do a comparison of the full diameters of the old wheel and tires I have, to what I'm contemplating. I'm sure there's a way to calculate it and figure it out, but nothing like an actual measurement.
By the way, I have several old 15X6 steel wheels with 7.00-15 tires (a couple of different brands). The old wheel and tire full diameters run between 28 and 29 inches.
Thanks in advance,
