GP2 Tire noise, oversteer/understeer.

9 posts by 7 people · 11 Aug 1996 - 13 Aug 1996

When exiting or entering some corners I tend to get some tire noise. It is not tire noise related to wheel lock. Is it 'normal' to have some tire noise or do I still have a lot more work to do on my set-up. Should I be able to set up the set up the car to run like some of the demonstration that have *NO* tire noise. Seems like it would be impossible to set up that well. Thanks for any help.

I have never been able to get rid of "tire" noise in any of the sims I run. If you get rid of it entirely, you are not pushing it to the edge. The trick is to get it down to a mimimum. Especially in sims that model tire wear and temperatures. Since we can't monitor the tire temps in GP2, I wonder whether tire temp is modeled? In some real forms of racing where the cars aren't as loud as the F1's, NASCAR's or Indycar's, I've heard the tires squeal. However, it is usually only for brief periods. Sustained tire squeal is bad. Not only does it indicate excessive wear, but lack of traction. Squeal = scrubbing of speed. Try to keep the noise down to a quite squeak and not a loud prolonged scream. -- **************************** Michael E.

: Is it possible to monitor wear? Yes, via the Advanced Car Setup. During practice or qualifying, when you pull into the pits and got to car setup, choose the Advanced level and "Inspect the Vehicle" This will also show plank wear. -- **************************** Michael E.

Yeah but how about when ya racing, would be nice to be able to change your pit strategy due to excessive/less tyre wear then expected Rob
: Yeah but how about when ya racing, would be nice to be able to : change your pit strategy due to excessive/less tyre wear then : expected You can, if you want to pit early, just press the enter key. If you want to stay out longer and you have enough fuel just press enter to cancel the call to come into the pits. You have the option to change the fuel and pit stop strategy while in the pits. -- **************************** Michael E.

Tyre noise may indicate that you are skidding too much or that traction is too low. But there will always be a little skidding if you are right on the limit, especially if you steer by using the throttle which again may indicate that you are overdriving or making up for understeer... But too much(what is too much?) skidding is never good. You may opt to soften springs or dampers, or maybe lower the ride height in order to get more down force. If you are driving heavily on bump ***s in a sweeping bend you could try to reduce the number of packers in order to get just a little more suspension travel, and hence more traction. But that may*** up the handling in other parts of the tracks where a lot of nimbleness is required(eg. in chicanes). Another remedy, and an obvious one it is, is to adjust your driving style. :) A typical turn where a some tyre noise is common is Curva del Sol at Interlagos. Since the right side of the car is very heavily loaded when you accelerate through it, the tyres may skid a little(some centimeters). Ideally a modern F1 car should not skid at all, ie margin for error should be zero, but that will hamper driveability in my opinion.

I was about to respond that you can't exactly stop your car at the side of the track, get out & have a look in a real race <g>, when I realised that the pit crew does get a good look at the first set used and can advise you accordingly. What we need is a really good AI for the pit crew! They could also let us know what they think are the other drivers' pitting strategies, times for the drivers we are interested in rather than just the ones immediately in front / behind, offer advice on settings during qualifying, etc. The next major leap in racing sims?

Real drivers can monitor their tyres by looking at them (they can see the rear tyres from their mirrors). Of course they can also feel their car handling changing when tyres wear down. In GP2, you can also feel the tyre wear, and you can also change the pit strategy during the race. Today I ran a 100% race in Monaco. I hadn't run enough tests to be sure how much my tyres would wear down, so I decided to start with three stop strategy, and decide on the run, if I would do two or three stops. I came in for my first stop on the 20th lap, and since my tyres were still in quite good shape (I ran my second fastest lap of the race one lap before coming in), I decided to run the rest on only one stop. I won the race, about 35 secs in front of Schumacher (on Pro-level). Samppa -- See my homepage for Formula One Shadow Series: http://www.hut.fi/~tax/ "Kuorma-auto - Hy?dyksesi tiell?"
