I've been lurking for a year.My first car was a '67 Bronco, 3 on the tree.

For me, the tire size is kind of a big deal. I love the way the '315's look but would not want to run them through a Wisconsin winter. Not only do I not do any off-roading hard core enough to reuire them, I run dedicated wheel/tire combos for the winter and would not rather deal with huge effective gearing changes and speedometer error. So 32.1 x 10 would be great for the winter with a slightly wider (but not taller) tire for summer.

Around here surface area is king. Snow is too deep to cut to the ground. All the snow wheeling rigs run 40s at ridiculously low pressure.

I for one am looking forward to 35s.

If the leaked axle ratios are correct, the 4.7 ratio with the 10 speed will turn 2019 rpm @ 70mph with the 315's

For sure.

Surface area/contact patch is always king except in very specific circumstances.

One such circumstance is where said pizza cutters can reach the asphalt or hardpack through the snow/slush/mud... which is a situation that many wheelers can attest is vanishingly rare offroad, despite the popularity of this myth.

I suspect most of the provenance of this lies with areas with winter temps that do not remain below freezing. Constant thaw cycling can produce slush depths on street roads that pizza cutters work well in.

I think I'll be aiming for the 285s, since I have 33s on the Jeep and they are more available both in number and brand variability than the 315s.

Look no further than 35" tires on a 17" wheel. No need to replace with 315s. Variety of 35" tires way far exceeds all others and u can change ur load range between a lot of options.
