Balancing tires for best race performance
By: Tech G Date: August 30, 2017, 10:19 am

Something I hear a lot of people having problems with is tire
temps and wear, which I rarely have any issues with and
generally am always able to run the S6 tire. Some of this maybe
driving style or just pushing too hard, but a lot is also about
balancing your tires. So, just in case anyone does not know how
to balance their tires here is a quick tutorial.

If you look at the image above, you have the out, mid and in
tire temps. What I tend to do first is drop the pressures to
minimum and do several controlled laps. Then check the temps,
if the out temp is more than 5 to 10 degrees low than the inner
temp you want to start reducing the negative camber, so less
negative. If the outer temps are higher, you want more
negative. Do this until the outer temp is ideally no more than
5 to 10 degrees higher than the inner temp. Do some more race
pace laps and keep checking as you make other setup adjustments.
Now if the mid temp is higher than the out and in, reduce tire
pressure if you can, and if the mid temp is lower than the other
two increase pressures.
Finally, it the tires are just not warming up, so say less than
60 degrees, you can also try to increase pressures, or maybe you
can drive a little more aggressively ;).

You don't want to be solely focused on temperatures in rFactor2.
Tires and suspensions are off, the URD mod is a shining example
of that on top of a seemingly awkward tire look-up table. Front
camber values should not drop below -2.0º, in fact they should
be hovering on -3.
About the temperature variation, you don't need to be focused on
<10º from outer to inner. I'd say 20-30º is acceptable if the
middle isn't too similar to inner.

Didn"t know you were running S6"S for the race Tech,for me S7"S
are only maybe 1 to 2 tenths slower and last much better.Your
probably smoother than me,I haven"t tried to race S6"S since
Malaysia but I had my degrees of rotation out of wack back then
and burned up my tires within 4 laps.

I would say that the URD EGT mod isn't that far off from real
world when it comes to caster and camber settings. I run mine
-1.3/-1.4 front, and -1.1/-1.2 rear.
TechG is correct about running a 5-10 degree temperature split
between inner and outer tire temps from camber. That has always
been the golden ticket for as long as I've been sim racing.

I think there not is a big difference between the two tire
mixtures S6 and S7.
Im preffered S7, full tank - S7 tires : and I ran 1,33,600 time
;D ;) ;)

Well, how much would you consider far off real world? ISI
Corvette GT2 has that fault too where you want to run camber
between -1.6º and -2.1º. Usually rF2 content is about 1-1.5º
less than real life especially for the front tires. And the
golden ticket is also minimum tire pressures. Before, the golden
ticket was either same temperature throughout, followed by 1-2º
variation from inside to outside. Then it became this 10º thing,
but as I said, the game isn't like that.

Interesting guys thanks. I have generally focused on balancing
temps across the tire and my cambers are often down to around -1
or below to achieve this. So what is the generally consensus?
Just run higher cambers and ignore the temps as this will give
better corner grip? Or keeping the temps balance as this will
give better over all tire life? :-\

I generally run the Camber that gives me the best cornering
regardless of tire life. However, I am also a mid-pack runner at
best so my opinion should be taken with a grain of salt. I need
to learn setups so I dont have to rely on the generosity of
others to get a "Good" setup instead of the setups I make.
(Mediocre at best, worst than default at worst)

I never liked the URD mods much, but there's usually two ways to
go about it. You can go that way and focus on temperatures as
long as you got low camber. Low camber is the key in rF2. Last
competitive race I did with URD you could push both focused on
temperature or go for what grip felt good with camber and even
very high pressure. I'd imagine -1.5-2º camber in URD could be
a sweet spot, don't worry about temps at all. Just be concerned
with tire wear, that's the key to being fast.

While higher cambers can make the car 'feel' better in turns, I
tend to stay away from them with my race setup, simply because
they also cause the inside edge of the tire to heat up
excessively, excessive heat = less grip = tires wear out faster.
This is because the higher camber makes the contact patch
smaller. I do increase camber for qualifying sometimes.
I monitor my tire temperatures. Tire temperatures and tire wear
go hand in hand. Higher temperatures = higher tire wear.
In the chart I posted above for the camber settings on the
corvette it gives you the optimal settings for real life front
and rear camber. I have tested them and had good results.
For the front it says: -1.00 plus or minus .6. So you can run
between -.4 / -1.6. I'm usually between -1.2 / -1.5 on the
front.
For the rear it says: -1.20 plus or minus .6. So you can run
between -.6 / -1.8. I'm usually between -1.2 / -1.5 on the rear.
Imola is the exception so far. My cambers are usually even from
front to rear, or .2 higher in the rear. At Imola my rear is .1
lower. I'm at -1.2 / -1.1
