I got a set of four of those for Xmas one year (!) and I bought a fifth to
round out the set. They were relatively inexpensive. They now have ~30k on
them, with a good bit of tread left. I check the pressure once a month and
rotate them (all five) at around 5k and other than that I rarely ever think
about them. We get serious winds around here in the spring and fall (gusts
of 50-75 mph are common), and while the van obviously still rocks it doesn't
squirrel around like it used to with whatever garbage I had on there before.

I've had the van loaded to the limit and haven't noticed any difference in
behavior or feel that I would attribute to the tires. I run them slightly
above the sticker pressures.
I drive moderately/conservatively, mostly on pavement and occasionally on
washboard dirt roads (I live in the desert SW). The tires don't give off
much road noise; basically I can't hear them over the other van noises
unless I listen to pick the sound out of the mix.
I don't often drive in the rain, extreme cold, or snow/ice, but on those
occasions that I have I had no issues with the tires. For instance; I got
caught in an ice/snow storm west of Flagstaff a few years ago, and I drove
in a proverbial "torrential downpour" on the way to L.A. recently and in
both cases I almost pulled off to wait it out (but didn't), but not because
of the tires. In other words, they were good to my acceptable tolerance of
all other conditions.
I wouldn't hesistate to buy another set, but I'm hoping to go to a larger
wheel before I wear these out.
