How can I set-up to improve tyre wear?

Stuck on the indy 500 endurance race, as I can only get 25 laps out of a set of tyres, whilst CPU opponents get 35-40 laps, meaning I'm pitting 3 times for every 2 they make. I'm in the Audi R8 LMP (same as 3 CPU cars), lap at same pace as them, but my tyres (racing hards) drop off much earlier than theirs, by lap 10 I'm dropping 0.5 seconds a lap to them, whilst the CPUs drop off is nowhere near as bad as it is on road course enduro's, so i can't push it to make up the difference. on Grand Valley I 3 stopped to win, CPU 2 stopped, but lost over 1 minute a stint due to drop off when they should have pitted, this tactic won't work for indy 500 though.
I'm currently have suspension set-up for oversteer (hate understeery cars), with a couple degrees camber, and low downforce. What set-up do I need to prolong tyres and keep my oversteery handling.
 
Lower the camber. Most of the time you don't need much more than 1 degree.

Increase the downforce, max front and rear. It will allow you to run the lower camber without sacrificing tire wear. Then lower the rear downforce until you get the right feel in the corners.
 
Yeah I'm no expert at tuning but I can say to just drive less aggressively - easy on the throttle out of them corners.
 
Mazda 787B is perhaps the best car on its tires and fuel, if you want to race legit (X2010 is fine, but cowardly in my books).

Other than that, ease up on the camber and toe angles, and go smooth with the throttle input.
 
Running RS tires when the A.I. are on RH tires is pretty much like cheating. He wants to win by running similar lap times and pitting at or around the same time.
 
Do racing softs last long enough to make up the extra pitstops?
Yep, I prefer to race evenly, I enjoy it more than just jumping in something excessively quicker and blowing the oposition away.
Unlike other Group C/GT1/LMP mixed races, all the opposition I noticed so far are LMPs, so I wanted to stick with an LMP, I do have a Toyota Group C car if I wanted to do it easily. Will try less camber and staying off the throttle, I did notice I seemed to be exiting corners much quicker than the CPU cars, although they then slipstreamed back up to me on the straight.

Try doing what they do, stay behind and take it easy then use the draft on the straights to stay with them. :)

edit: also, on Indy you need max downforce, not "low".

For the record, it has been discussed and confirmed in numerous other threads that "racing soft tires" last just as long as "racing hard tires". Depending on the track/car, they will be 1 to 5 seconds faster per lap. Occasionally, you may actually find soft tires last longer than hard because they slip less and therefore scrub off less rubber per lap. However, if you drive both sets of tires equally to their limits, they usually last about the same length.

The compound merely refers to how much grip they have, not how long they will last. It is dumb, we know, but that is the truth.

indy 500 is the wrong place to have a close race... its a oval man^^

just drive all the time at the left side.. so you dont giveo slipstream for the others, if you are 3-4 sec away i would change back to normal racing line.

for tiresave adjust your tuning setup... lower the chambers etc make the suspension bit harder.. fullthrottle at cornor exit eats tires too but this is a 100% fullthrottle track with a LMP, maybe you set the 2. LSD setting(accerlation) at 5.
 
did it last night, thanks for the help, not only could I go a lap further on soft tyres, (wtf?!) and lap 1.5-2 seconds quicker, they didn't drop off as much as the hards did, meaning by lap 25 i was 4 seconds a lap faster than what I'd be on hards. still had to pit 6 times compared to CPU cars 4 stops, but had the pace to win it by nearly 2 laps.
 
I did some experiments on that race. Tire wear pretty much depends on the driving style and aggressivens. If you attack aggressively and tires are skidding on every corner, you will get 20 laps per set for the racing softs. If you keep it under the skidding/squeeling treshold, you can get almost twice as much (and lose 3-4 secs per lap). It's up to you.

To my knowledge Racing Softs last just as long as RH's in GT5, actually all of the racing tyres last equally long. Don't know why that is, though.

And that's utterly and completely wrong, as max downforce creates far more air resistance, thus increases the need for power and torque to reach same speeds as with low air resistance. Min downforce creates less air resistance and drag and thus makes the car have better top speed. The lower the downforce, the less the air resistance and vice versa. With low downforce the X2010 can reach speeds of 480kph+, but with high downforce it tops at 400kph - that's just one example.

The AI are on Racing Medium's. All of the races that have no tyre restrictions in B-Spec have Racing Medium using AI racers. Also Racing Hards don't actually have as long a life as RM or RS because of a glitch in the tyre wear system with grip and all.

He's not talking about the X2010. For "real" cars you get faster laps and longer lasting tyres on Indy with max downforce (actually all tracks except daytona). But you go on thinking that's "utterly and completely wrong" all you like...

If you add max downforce;

1. Your top speed wont be par with your AI opponents (Considering you're using "real" cars)
2. Your tyres wear marginally faster (Pit-in 1 lap earlier than low downforce)
3. Indy doesn't require Max downforce, only enough to take the corners at a good speed.
4. The advantage you gain on the (4) corners with max downforce is lost on the straights, which make up 75%+ of the track.

So yes, you are:

Have any of you even tried that race?

With a completely stock R8 '05 (OP didn't specify which he used so I picked the slower one) on max downforce, I get 40.6 second laps on race hards. I just gave it a quick stint and I was in the lead by turn 2 and lapped the field by lap 14. By 27 I lapped the field a second time before getting my slowest lap time of 41.3 on 29 then I went to the pits on 30. Came back out to a 25 second lead.

With minimal tuning to the suspension I can see 34-35 laps per set and quicker times, which if I recall is about what I did when I first ran this race a long time ago in this same car... But I'm sure that had nothing to do with me setting up max downforce - I must just be the God Of Racing or something, turning left is quite hard after all.

tommoore: If you want to win the race do what chuyler and I said, increase downforce.

edit: With minimal tuning I got 40.2 and evened out rear tyre wear a bit, should give a few more laps and another 10-15 second gap per stint.
