Hey there...

I am racing in an endurance series with my mates. I noticed my tyre wear is much bigger that my competitors (I know driving style play a big part here). I was wondering does anyone have experiance tunning the car for better tyre wear??

What car and what track? This would really help.
 
Well, I'm just guessing here, but tuning the camber for maximum straight line traction (so the tires are flattest on the ground) may decrease tire wear. As well, 0 toe on both front and read may also help as that should decrease scrubbing...?

killerjimbag may be right though, might depend on track a fair bit.

Disclaimer: I have done no experimentation. All other posters, feel free to correct me if I'm wrong
 
It might just be your driving style. Run a lap or two then save the replay. Watch the tire gauge during the replay. Anytime you cook a tire (make it red) you are over-wearing it. Depending on what tire and what part of the track you should try making adjustments so the tire doesn't turn red. It's real tough to race some cars without lighting up the tires but keep in mind a red tire has less traction so even though it may feel faster, running the tires in the red is usually slower.

Motul GTR'08 and Cote 'd Azur.

I increase ABS to test it out, doesnt seem to help much.

Get rid of the ABS set it at 1 max.How much down force are you using.
Post your setup and I will take it for a spin.
Hard to explain if I don't know what you are driving with also.
Wheel or controller?
 
Get rid of your camber and toe.
Your individual lap times may drop a little, but your 10 lap average should be faster. (Due to prolonged tire life)
 
When looking at replays of monotype races, I saw that the same car can have important differences in tirewear and tire temperatures, depending on set-up and driving style. In 25 minutes races, results are often determined by the grip that rests during the last laps.

Had some testing last week for the WSCC Group N FF-cars day and for the lupo series

FFs have huge tirewear. We tried the following and it helped:

- light TCS (1 or 2)
- play with LSD-setting and put it high enough to prevent tires get "red" when you accelerate.
- avoid heavy toe or camber settings.

And of course, driving style plays a role also.
 
There is another thing that prevents the tyre wear (at least for FF cars); the difference between front and rear height. If the front is higher than the rear, the car will have much less tyre wear, even rear tyres can be more wear than front tires if the different is quite big (30-40). Did you know it? do you know why?

PD: You can try it in Focus ST'06

If you make the front as high as possible and the rear as low as possible it can basicly turn a car that understeers into a car that oversteers. So because you have less understeer your not fighting with the car as much round the corners ie better tire wear, but it is a balancing act if you have too much oversteer it can make tire wear worse.
 
I'm in a little different place than some other respected tuners in this thread. I have not found that 0 camber and 0 toe offer prolonged tire life. I'm calling that myth until someone can show their testing. I have run 3.5/3.0 camber and had the same tire wear as 1.5/1.0. Camber shows most of its affects (and tire wear) in the corners, not driving down the straights. Why would I want to optimize camber for the straights, not the corners. On all tracks we spend more time in the corners than we do on the straights.

I have seen aggressive tire wear come from what others have mentioned - red tires. Red tires can come from driving style and the tune. I find red front tires are often caused by too low of a camber setting. I also find that the overall tune balance is the biggest factor. Setting up a car that is neutral - no push, no oversteer is the key to tire life. LSD, ARB, Brake Balance and Camber (tuned for corner grip) can make a big difference.

+1 on that one. In the FGT series that I race in I used to run 2.0/1.0 camber but after putting it up to 3.5/2.9 and the tyre wear was reduced by a fair bit. As said before the times per lap will be slower but in the long run it is better to have it 3 tenths down over a lap than having to pit in for 45 seconds every 11 when you could go to 15+ laps. :)

I have done very many around 70min races in GF500 cars, and I second this point. Its imperative to get to even front/rear tirewear to be comeptitive over the race distance. If you get to even tirewear, the overall wear is also better.

At most tracks, for FR cars front tire wear is the main problem due to inherant understeer. I find the medium speed corners being the most challanging not to get into excess front tirewear. Most often I end up with a compromize between tuning in as much oversteer I can handle for drivability on fresh tires, to avoid the front tires wearing out quicker. Some tracks are worse than others, Suzuka being a very challanging one.

Some tracks with mostly long straights and slow corners its easier to get to even tirewear or even excess rear. Daytona, SPA, Le Mans are tracks falling into this category. Intersingly and slightly surprising, Monaco also get higher rear tirewear. The main reason is probably that you have to tune in as much oversteer as possible to get to fast lap times, and there are no corners where a strong oversteer cause problems with the handling.
