That's true, he says so in black and white.  Maybe he'd be happier with
a cookie from his buddy?

I should add that you clearly have never seen me chew someone's ass in a
Usenet post, because when I really do, it's rather obvious to everyone.

I'll just note that the inflation over the Toyota recommended pressures
35psi front, 33psi rear, started back with the Classic Prius.  Many
owners noted premature tire wear, particularly on the edges (which is
usually an indication of running the tires at too low a pressure).
(But a few stuck to the Toyota recommendations and didn't notice any
problems.)  Many owners then tried increasing their tire pressures up
to the max. cold pressure on the OEM tires (Bridgestone Potenza RE92
XL) of 50psi, and then backed down to where the ride felt comfortable
for them, which was usually in the 40psi range (add 2psi in front).  A
nice side benefit of longer tire life was slightly better fuel economy.
 (These OEMs would typically wear out by 30,000 miles.)

When the NHW20 Prius came out, people just followed the recommendations
that were there for the Classic.  US OEM tires (Goodyear Integrity)
have a max. cold pressure of 44psi.  Again, a few have reported uneven
edge wear...

I have yet to see a report from a Prius owner reporting uneven center
tread wear, indicating that the tires are overinflated.

Mine have been at 42/40 for the past 10K.  Tires were rotated at each 5K
service interval.  According to my 15K service report tread wear is uniform
across the surface.

Ok Mark, get in here....you got some splainin' to do. How can a car be rated
to have tires that are inflated to some certain pressure? And if they are,
do you really think the car itself will be raised some amout that will raise
air resistance enough to offset mileage? I didn't even conceive that you may
be serious, so said you "may" be making some kind of joke. You had to be
joking, right? Maybe Mike's right, maybe you were serious? Sorry Mike, I
really thought his post was for humor and that that was obvious because it
was so far fetched, so I got defensive when I made what I thought was an
ovious observation, that he was kidding. Looking back, he gives no
indication however that he was though. I'm gonna go back and hide in my
garbage can for a while.
