I guess to my uninformed self, it seems that the failure mode for most of
these tires is focused on the sidewall, and especially the extra tall
sidewall of a 70 to 75 series 14" tire.  I would theorize that my 50/55
series sidewalls are less prone to flex and bulge issues that either blow
out or separate from the rim.  My van is primarily used as a local
people/junk/lumber/hardware hauler.  I try to never travel any more than 60
miles (to IKEA) in the thing, 'cause I have other more comfortable cruisers
for such things.  I do routinely drive @ 70-75 mph, though.  And I like to
flog this beasty around corners, especially now that my rear stays glued to
the road rather than sliding out like my old 14" Uniroyals (with proper load
rating).
