315/80 vs 12R - was Overweight

[Don Bradner]

No problem mixing on different axles. Until yesterday mine had Michelin
(steers), Goodyear (drivers), and Goodrich (tags).

I expect to always have mixed sizes, as I am not going to put 315s on the
drivers. While it might be possible (Shane is doing it) with 8.25-inch rims you
have to over-inflate to keep adequate clearance between them. The 315 is an inch
wider than the 12R. It is also 0.3 inches smaller in diameter, but that won't be
obvious on either steer or tag.

Fred, my tires don't come anywhere near the jack pad, so they must be
differently positioned on the 90 compared to the 97.
