I know various forums have been made for this and stuff but I as hoping for an answer that directly applies to my situation. I'm trying to run the 24 Hours of Le Mans and would preferably run it in my Team Peugeot Total 908 HDi-FAP, which I barely choose over my Audi R10 TDI, but I'm willing to run a differed car if those two don't work out. Now here is my problem:

The rear tires arent lasting as long as the fuel load is. After 7-8-ish laps I need to hit the pits for tires, which is very annoying because my aim is efficiency, which is why I choose diesel power, but again I will change that if I must. I attribute most of my tire wear problems to the fact that I haven't had a chance to buy a steering wheel controller yet, so I'm stuck with a normal controller. My gas and brake is still the X and square buttons, because L2 and R2 and my paddle shifts. I seem to have gotten quite smooth with my cornering and pretty smooth under braking, but it obviously isn't cutting it. Therefore, I need to rely on the cars set-up to improve tire wear. The front tires are fine, they aren't wearing much at all, it's the rear tires that are the problem.

On a final note, both the cars I was hoping to run have 100% stock set-ups on them, except for tires, for the reason that I want to keep the speeds even with the competition. Running a 24 hour race I don't want to be playing bored of no competition for that long. So hopefully the setup can keep the speeds even with the competition like it is now. I have a week off of school next week and I was really hoping to run it then, so PLEASE help me. Wether it's general tuning information or set-ups that work for either my R10 or 908, or a different car for that matter, I would be very grateful for it! PLEASE help me out and thank you on advance!
 
The A.I.s will be pitting about every 6 laps, so as long as you can keep equal lap times, 7-8 lap pit cycles will be more than enough to win.

If you're really concerned about it, though, the reason the rear tires aren't lasting as long is because you're putting too much pressure on them when you get back to the gas. As a personal driving style, when I did the race in a 908, I never shifted below 3rd gear, even in that slow right-hander after the second long straight (turn off the back straight down the long two-lane road with a dog leg - make the left onto the side road and it's that next right). If that's not doing enough, you might also consider making some of the lower gears a bit longer so that there's not as much torque on them.

Failing that, it'd be a matter of adjusting the driving style, though I can almost guarantee you that if you get yourself to needing gas before tires, you won't be going fast enough to win.
 
See because it seemed like, with the exception of the 2003 Pescarolo, they were all beating me by at least 2 laps
 
I had that problem too. I think it's the high torque that the engine produces as I also could do only about 7 laps before my tires were shot. You might want to try a different car though if nothing works. One with less overall torque output.
 
If you don't mind it being a standard car, the GT-One is another great choice. It has the torque but not overkill like the diesels. I can go 8-9 laps depending weather conditions.
 
You can use a Audi R8, I once won the same race in that car with 100% raining conditions going on for about 22 hours. Unfortunately, I'll have to pit every 4 laps at least, which is the only disadvantage over the AIs.

You can also change your 'gas and brake' from the buttons into the sticks.
 
Now what kind of tires are you guys running. I feel like since the updated it my tire wear has got worse. The Porsche curves seem to chew them up like crazy.
 
Not done any of the 24 hour races yet. ive got 3 hours left to do on the 9 hour track and ive been using racing hards. Softs lasted no time atall.

Could always go mediums on front and hards on the back?
 
I strongly advise you change your L2/R2 for breaking/accelerating and use the right analogs up/down for gear changing.
Not only does this allow you to feather the throttle, but you can break much better.

As for keeping the car from spinning you should break, gear down, accelerate immediately and back off, and break again. I don't know how this is called, but that's how rally drivers corner.
Learning this move will tremendously help you when it starts raining and the track is slippery; unless you're using aids.

And using the analog up down for gear changing feels somewhat realistic. Literally a miniature sequential gear lever for your thumb. :P

EDIT:
What about lowering the PP of the car via engine limiting. Less power = less wheel spin = longer lasting tyres
Plus in the rain high BHP isn't going to be of any use.

Or how about setting up the gear ratios for a very slow acceleration and/or a much higher top speed that you could possibly reach. This will allow for a more stable and progressive acceleration, which will help a lot in the rain and the slower you go, the less tyres you will use.
Also I noticed that when the car is toping out, the tyres burn much quicker (but I can't confirm this one 100%).

Another idea would be to lower the break biases and break much, much earlier. The softer the breaking, the less tyre will be used. Since for the most part, the tyres will be burned out due to breaking from such very high speeds.

EDIT 2:

This is the controller setup I came up with, which would allow for the best usage. Having that RA Function, will allow for on the fly settings adjustments which will definitively prove useful over the course of 24 hours.
Like adjusting break bias depending on how the tyres are wearing out, or to help cope with rain, and so on.

EDIT 3:
Found this tune for the 908. It's by far the best one I tried so far and only the transmission needs to be setup differently (obviously) to run it on La Sarthe

I,m using the Formula Gran Turismo for this race and its been 100% wet for 11 hours, the rain tyres are barely worn after 15 laps but fuel is almost empty. Running in the night with no lights is tricky though!

Would you happen to know how long RH tires on a Sauber C9 would last at Le Mans?
Click to expand...

Round 7-8 at around 750 HP limited with stage 3 turbo.

Averaging 7 though because by the end of lap 8 it can become really dicey if you're not easing out of corners.
