Tire wear issue, advice from pro tuners needed

[HF_NOS]

Hi everyone,

First sorry for my bad English.

I have been racing in a GT500 endurance league for the last 2 weeks.
We want our race to last 50 minutes and calculate the laps by doing the following example:

Deep forest reverse pole time is 1.04.6
50/1.04.6= 47.8 laps.

In those 2 races I have been in there was something I really cant understand.
Every racer except 1 needs to pits twice to get a pace of 1.06.1
This 1 racer could keep his pace very high and still pits only ones!!!

I was driving behind him and was looking after my tires but after 15 laps I had to pits otherwise the car couldn't steer anymore and my pace will drop to 1.08.x

Is there anything I can do to reduce tire wear when tuning a car? and especially gt500 car (calsonic)

At the moment im running low camber F1.8 / R0.8
and also very low Toe F0.00 / R-0.15

LSD settings are 8/7/5
max AERO

Try lower downforce levels. Be sure not to use ballast.

This might sound weird, but beat the crap out of it to tweak the chassis, run many laps don't repair the chassis. Drop to a lower tire grade and tune the car then. This will make the car handle better after many laps and you might be a le to push it some more laps before a pit.

Messing with your brake settings/style might help also.

Good luck, cheers.

I did 10 laps with the arcade mode car.
The car has extremely even tyre wear and the tyres were 1/4 gone after 10 laps.

I agree with AssassinT, and to me it sounds like you should try adjusting your corner entry. If it's your steering thats going out first, you may be able to drive less aggressive into the corners, and more aggressive out of the corners to save tire without sacrificing time.

Guys try to get 1.04.6 with calsonic 502 bhp at deep forest reverse and then come talk about my driving style.

I push the car to the maximum. @raVer im getting 1.05.3 with recommended calsonic and tire wear is not all to bad, but still after 6 laps I cant get fast times anymore.

Please try 25 laps with racing soft and try to keep your pace at 1.06 low.

In the race I try to manage my tires but 25 laps with fast pace is not normal. and why is he is the only one in the league that is capable of doing that?

Do you steer more than you need to?

Once a tire exceeds its ideal slip angle while turning, its grip stops increasing and will begin to decrease. Turning with too much steering angle and therefore too much slip angle will rapidly increase tire wear. With some experimenting, most drivers will find that they can actually turn the same amount with less steering angle, thereby carrying the same or slightly better speed through corners while minimizing tire wear.

That is a lesson from real-life racing. I'm not sure how slip angle relates to in-game tire wear, but it is a very basic concept so I'd be surprised if it wasn't a factor. It's very difficult to estimate the optimal slip angle in a video game without any steering feel, but practice makes perfect.

That's my two cents on a method that the majority of gamers don't consider. Finesse.

Okaaayyy...asked for advice, offered advice, get a smack in the face...OBVIOUSLY your a way better driver then us, so why you asking? *unsubscribed*

We are not dogging your "style" tire wear is a product of driving style as well as Tune. Aggressive "pushing the car to the maximum" is brutal on tires, not to mention brake settings and use are critical to tire longevity.

I also offered a technique to help you car perform better after being on the track for hmmm around 15 laps...

You asked for help, we are pointing at the first areas to address. If you snap at the help, nobodies going to help you...

I suggest uploading a 10lap replay video to youtube and post it here , so we can analyze your driving.

I'm not an 'expert tuner' but here are my findings.

I bought a Calsonic GTR from the NCD. Changed the oil and added RS tires.

Took it to DF Reverse and ran a couple of laps. Applied a rough tune and got times into 108s. That was close enough to get some data.

Car ran 10 laps before tire wear started affecting lap times by 1 second per lap. Tires still showed plenty of life left and I estimate I could easily run 25-30 laps on them.

To get the car into the times the OPs describes you need full downforce, very low ride height and very firm springs.

To the OP...these settings are why you see high tire wear. (I don't believe any change in driving style would significantly change the wear you see in races).

You have a decision to make: Either set your car up to put down fast lap times, or soften it up a bit, get slower laps, but improved tire life.

(on the other hand, you could try changing cars to see if a different car, like the Epson or Takata NSX is better on tires)

I think this is a question of race strategy to position yourself for the best result, not tuning or setup.

I now have read this a couple of times: Higher downforce increases tyre wear.
My understanding up until now was quite the opposite - high downforce keeps more pressure on the wheels, preventing slippage, hence reducing tyre wear.. Why would it be the other way round?

Thanks for the advice. thats the help i'm looking for, because I clearly stated that i'm not the only one with this problem. so its not my driving style. 15 guys had the same issue and 1 guy didn't

You are right about my setup being extremely stiff. soft setup on DP reverse wont give me fast turning response when needed.

About high downforce and tire wear. One day I took a nascar with low downforce for 20 laps, did the same but this time with high downforce. High downforce was allot better for tire wear.

Another question: Is it possible that LSD has an impact on tire wear?

I'm running low LSD and often see my outside tires turning red when taking a turn at the limit.

Your outside tire still gets red even with a setting of 8/7/5? Woah!
Do you mean front and rear tires or only the rear one?

Front and rear. If I set to 10/30/30 then there is no red anymore but same goes for traction coming out of slow corners.

 

[dr_slump]

Could you post your whole setup or is it a secret? If yes, no problem.

 

[iamjajo]

You could try increasing the first value of your LSD (Initial) to 10 or 12 to see if your tire wear improves. But, you will be a little slower coming out of the corners.

From my small experience with this car, I would suggest trying this:

12/20/10

About the downforce comment. I don't think you can single out one component of a tune since they all work in concert to give your car its performance.

 

[Sol_Badass]

This might just be me, but those fount chamber and rear toe setting are leaning more towards medium-ish (if you know what I mean). Your at about 500 hp right? I tend add 1.5 and on my FR super gt cars at around that hp.

Having toe out on FR cars is bad for tire wear too, since the rear will get thrown out more on corners. Also higher chamber and toe setting are will almost always increase tire wear in exchange for nimbler, or more controllable handling. Increased LSD acceleration sensitivity will help too.

 

[shmogt]

Everyones advice so far should help, but I found LSD to be one of the most important things for tire wear. I haven't tuned this car so im not sure the exact values, but make sure the tires never go red. Usually initial will be low, acceleration will be the highest and braking will be kinda in between. 10,50,40 something like that. Just keep driving it and adjust until you find the perfect values.
