How to deal with tyres of F1 cars in Monaco

[Hikari]

I found that the rear tyres of F1 cars would be worn out very quickly in Cote d'Azur because of the extreme accelerating and breaking.

Any one know how to deal with that problem? Will tuning the balance of the car's weight be useful? ^ ^

Try uping the TCS to three, it works for me^_^

Um...strengthening TCS may be useful...

Setting the camber to zero on the rear wheels wil improve tyre life.l
Edit.
I actually meant toe. Typed wrong word. sorry.
Won all 10 races with rear toe set to 0.
Improved tyre life to 8 laps at the Cote.
Some races lapped complete field.

Actually, I don't find that camber is the issue in tire wear so much as toe. Camber definitely has little effect on top speed.

The F1 cars are set up with massive toe out in the rear (like -3.0) to make them twitchy and very quick to turn in. If you reduce the rear toe to -1.5 or so, they still rotate well but you get better tire life. If that generates too much understeer, then back off the camber a little as Uncle Harry suggests.

The other trick is to really just comncentrate on smoothness. It helps tire life, and you'll find it usually helps lap timems as well.

Good luck!

In addition to the toe and TCS (and maybe upping the "Initial Torque" LSD setting), make sure that you "screech" the tires as little as possible. Namely, don't mash the accelerator when existing a corner &edash; Get on it as quickly as possible without spinning the tires. Also, try to avoid braking while turning – Instead, brake in a straight line, then turn in. Otherwise, you'll rub the tires when going sideways and decelerating, which ups tire wear.

Just keep those in mind, and try to be consistent lap to lap, and you'll be fine. I beat the 2nd-place car by several laps, and I'm not very good.

The rear tyres get better life when rear toe is reduced ?
Um...the preset of F1 cars are too overkilling...

And I have done a simple experiment: I did't need to do anything on camber when toe is reduced to -1.5. It worked well.

Maybe that must be set according to personal driving habits.

(When I drive traditional race cars in Monaco, I use harder rear tyres, but F1 cars can only use Normal Tyres...T_T)

Yes, they do. "Toe" other than zero means that the tire is sitting at a slight angle to the centerline of the car, meaning that when driving straight forward, the toed tire is always being forced sideways slightly. Reducing this angle reduces wear.

Good. It does tend to reduce the turn-in a little, but if it wasn't noticeable you are good to run. Keeping the camber at stock will help with rear grip a little - better than having to reduce it.

Well, the real F1 cars are set up to respond VERY quickly, since stability software (when allowed) and complex limited-slip differentials help the drivers keep fundamentally unstable cars together.

I've noticed that my car turned a little slower in low/medium speed corners if I reduced toe. (For example, the southeast "tail" of Grand Valley Speedway)

Reading neon_duke's posting, I learnt much, thanks very much! =v=

You are more than welcome. If you have not already, read through the stickie "///M-Spec's Pocket Guide to Suspension Tuning" at the top of this board. His explanations are very clear.

I know for a fact a lot of Honda NSX owners get their rear wheels straightened out because they come out of the factory with like 0.4* of toe out or something.

They do it to save their tyres, so no toe helps

About that mentioned pocket guide to car tuning, where does M-spec live? It's called downforce not download

Also, where I come from, downforce is almost always an aerodynamic term.

Ummm, could it be that he's not talking about the same thing you are?
