high psi.. more resposive.. but less TOTAL grip
lower. less responisve.. but higher overal grip..
BUT.. should be set to EVEN the tire temps...
James
PS.. pity SCGT does do temps :-(
As to tire pressure. Yes, lower pressure can give more grip but not be
responsive. Also it tends to heat up the tire too due to more friction.
High pressure is just the opposite. Tire temps can be handled somewhat by
pressure although the middle of the tire is the portion that tends to
benefit most but across the board the temp of the tire is effected by
pressure. The outside and inside edges can be managed by setting your
camber right. However, all these tuning techniques are utterly useless if
you can't even see what your tire temps are. Given than they are not
present in the game I have to wonder if they are modeled at all.

'Sides I said Big Brother of GT, i.e. its what I would have expected from a
more matured GT that was presented on the PC. Its not a sim racer, but its
a pretty good arcade racer. However, many of its shortcomings deflate the
good attributes of the title.
I have an Audi A4 FWD (sadly, not a Quattro), and I have yet to find the
right pressures. But I have also heard a zillion opinions on the subject
too! Hell, I even had one guy tell me to run only about 20psi in the rears,
and 45psi in the front!
So far, it seems that on my new Toyo Proxy T1+ tires (235/40/17), 38-42psi
front seems to work pretty good, but I am still not sure what works right in
the rear. And as you only get 3 chances in a Solo II, there is no real way
to test correctly. One event the rears seem good at 4-10psi lower in the
rear, and others it seems that 4-10psi higher in the rear works.
Now I am not a newbie to Solo II, as I started in 1974 (and a lot of track
events too), but all those years I was in a RWD, and I quit in 87, so I am
rusty, as well as new to FWD.
As it is now, a guy from Activision is in our Solo II series in the Sport
Truck class.

Well, I'll find out this weekend when I go for my first autox in 3 years, and
with a different car. Regular HR-rated tires, I'm setting high P. But with
my old Goodrich R1's, I went with pretty low P.
What kind of car is it. That will make a big difference. I run my
Goodyear slicks at lower pressures then most guys with DOT rated tires.
The DOT tires seem to have softer sidwalls and roll over much easier and
that is why you pump the pressures up. If you roll the tire over to the
sidewall, you loose adhesion, with racing slicks the sidewalls are so
stiff its not a problem.
Front drive cars like more pressure up front due to the wieght they carry.
But due to the tight corners you find in Solo ll events even a rear whell
drive car will run high pressures. I would recommend at least 5 psi higher
then what you run on street minimum and I see some guys run Golfs and
Civics with as much as 45 psi in the fronts.

Back to sims, I'd really like to see an autox sim, or at least a Gran Turismo
like sim where you drive real world cars, with the ability to do realistic
modifications. A few years back, I talked to one of the better known game
designers (actually, about the best there is) who is also a national-class
autoX'er about doing an autoX sim. He thought it too much a niche market.
Maybe with the popularity of Gran Turismo, and the increased popularity of
non-traditional PC racing sims (ie, not all Nascar/F1/ICR), maybe I should
advocate again?
That is a good starting point, I might go higher if tires roll over too
much. The rears you will want to raise or lower pressure to get car to
turn in better. On the Integra they basically hold the back of the car up
so you can tune in oversteer with them by adjusting pressures.
There was a part of Hard Driver years ago that had a autocross portion of
it. It was neat, but very hard to judge corner entry speed. I usually
ended up understeering off the track alot.
Good Luck.

Mike I wish I could help, but with my slicks and 1600 lb car I run like 25
psi in the front and 20 in the rear. I have had as low as 18 in the rear
to hook up on bad surfaces, but remeber my car runs prepared and uses a
very soft compound stiff sidewalled tire.

I tried the VR demo, but I can't get into a 1-car sim as much as I can a
1-plane sim.
I could tell you ...
Well, okay. It's Andy Hollis, of Janes Longbow and F15 fame. At least in the
past, he raced CRX's and MR2's (or was it Neons?).
