The worst hills I'm worried about are probably 10-14% and short enough
to be stomped in 53x19 or 17 so. This will involve standing of course,
and probably a fair amount of thrashing side to side. So lateral
stiffness could be an issue.
So to make sure I underatand the reasoning: radial up front to be as
stiff laterally as possible, and 2x DS rear to provide torque
transfer, radial NDS (heads in) to provide lateral stiffness. Correct?
