Tire pressures are dependent on many
factors. tire wear is one of the best ways to judge tire pressure.The down side
is you need to run the tire for some time to get a
reading . so many tires, so many
applications,so many variables. the best way to start is with the
manufactures recommendations. BRADFORD 1451

Subject: Re: [Vmax] Tire pressure
I was running the recommended 32 PSI on my "P-51". I had
such a bad high
speed shimmy that I was almost high sided of the bike at
120MPH! I went to
the tire recommended 40 PSI and my Mr. Max is
steady to 145+ MPH. After 145
I do not have the balls to look down
at the Speedo!!!! They say that this
was the problem with the
Firestone Wilderness tires. Firestone recommended
38 PSI and Ford on
the Explorer recommended as low as 25 PSI to aid in
prevention of roll
overs. Don't ask me why but that was a memorandum
released by
Ford. My Canine ride is a Ford Explorer with Wilderness tires.
Firestone stated the lower pressures in conjunction with summer heat and
high
way speeds of 80HPH+ was the reason behind the tire tread
separation. They
are still selling the Wilderness in locations
through out the world. The
recall here in the states was
voluntary. Again this is my humble opinion.
I have been
known to be wrong in the past. But as long as you do not over
inflate the tire rcomended pressure, you are going to have less
heat/wear/cupping than if you were using a lower pressure. Each tire
is
rated for a certain weight. As long as the load on that axel is
under that
weight, the stated pressure is safe.
Now if you are
talking the strip or the track, lower pressure (to a point)
does provide
better contact/grip; but I think a race only type would serve
you better
than screwing with the PSI.
I lost a friend in the early 80's that had
a 800 Kawa. He placed NOS system
on board and was trying to get the
rear tire to hook up. He went down to
15PSI and ended up having a
rear blow out at 110MPH on I-10 in New Orleans.
Spent about a month
in the hospital and lost a leg. Don't get me wrong I do
not think
the tire rated pressure is God's word, BUT I do not think you can
go wrong
by following it. Might not give you the best performance, but I
want
to ride until I am an old man. Right Don?
