Hi All,

I have done the s class race at Sarthe a few times and noticed the same thing every time.

Last time I used the Minolta Toyota, and for first stint used RM tyres. I pitted at the end of lap 3, my front tyres reading 10 10, and rears reading 9 9...

I get a new set of boots {RM}, and a tank of gas, then off to go.. However I now have to pit after only 2 laps coz my rear tyres are shot, down to 5 5. I also noted that in the second stint I could hear the rear tyres squealing, even when running in a straight line, and car definitely had less rear grip throughout second stint.

Now call me mad, but that seems a little inconsistent to me. Is this something others are experiencing also?

I've raced every S event several times in several MR cars. Every time, my front tires wear more than the rears on the first stint, and the rear tires wear more than the fronts on the second stint.

It will be interesting to see how this works out over longer distances. Perhaps some of our online distance racers will know the answer.
 
In the 24min of LeMans race the beginning is wet. I gets dry after lap 3 I think. If you're using slicks on wet track (which only works so well because the griploss is set to "low" in career mode), they hardly wear at all. But if it dries, they will wear and the true tyre wear of your car comes through.

Another factor in those races with the very high wear is driver contencentration. If it goes down in the second half, you might not be that gentle with trottle anymore, which is a very big factor with high power cars.
 
It's a bug, for some reason the set of tyres you get in a pit stop are worse than the originals - they wear quicker and even when new end up being several seconds a lap slower from what I've found. Doesn't just happen at Le Mans, but pretty much everywhere else too. I'm assuming the constant tyre squeal sounds are part of the bug. Concentration shouldn't have anything here, it's a 24 min long race at most, not a 3 hour stint.

I have tested this and made sure the second stint was driven as an easy pace, short shifting through the gears, lifting off early before breaking zone, gentle breaking and coasting through corners, and not worrying about lap time, or final position (although I still won the race).. In fact taking every step I could to maximize tyre life, so that is not a factor.
 
Looks broken to me. 3 laps on racing softs- fine, then no grip on rear totally wrong. Tried putting racing hard and couldn't keep the car on the track. Even I'm not that bad of a driver.:confused:
 
I've posted the below in a related thread. There is definitely an issue here.

The second set of tires issue has not been fixed yet with the 1.03 update. For those that are still arguing about whether this is a driver issue or a real "bug", let me assure you it is a real bug.

I am part of a league that does endurance racing and has been racing together for over 3 years. By that I mean that all of our races are a minimum of 1.5 hours in duration and require a minimum of 2 pitstops per race. As a result we have extensive experience running on second and third set of tires. Not only are the laptimes on average 2 seconds per lap slower, but there is a distinct difference in the feel of the car once you have switched to the second and third sets of tires.

As an example, we are currently preparing for our race on Daytona Road Course (2.4 hour race, full 24 hour time progression). The cars are limited to 532HP and 1100KG minimum and limited to Racing Mediums. The room is set up with all settings to REAL and damage is set to HEAVY. Only TCS and ABS are allowed, and almost all members run with TCS=0 and ABS=1, including myself. My weapon of choice is the RE Amemaiya RX-7 GT300 Base Model.

First set of tires - Average laptimes of 1:41.5xx, with fastest lap of 1:40.849 (20+ laps)
Second set of tires - Average laptimes of 1:43.3xx (20+laps)
Third set of tires - Average laptimes of 1:43.3xx (20+ laps)

Not only are the laptimes slower, but the FR cars lose a significant amount of front tire grip on the second and third set of tires compared to the first set. This is most noticeable when turning into the International Horseshoe as well as entering the Bus Stop. In the two horseshoes it is also noticeable on corner exit as the car slides wide. The front tires simply will not grip the way they did on the first set. The same issue is true for both the FR and the MR cars. The change in grip level on the front results in an FR becoming "less" drive able on the second set and the MRs becoming "more" drive able on the second set as the MRs start off with very little rear grip on the first set and gain rear grip on the second set.

The loss of front end grip means that cornering speeds are reduced which results in slower laptimes. This is not a matter of "learn to drive". This is an undeniable "issue" with the game. It is also not an issue of certain cars being "broken" as it affects all cars that I have tested so far.
 
Noticed the same thing. First two laps in rain with RM on, no problem. Didn't really baby it and 0 wear (10 for all tires by the end of the second lap) Pit. Same tires. Can hardly make it one lap and my rears are down to 6. Doesn't make sense.
 
Hi guys,
Anyone else notice their car pulling right or left under heavy braking on the Sarthe? I was using the Pescarolo, is that a common handling characteristic of that car or track? It never happened in any other race with any other car until the S series on the Sarthe circuit, or i just never noticed it before. But it was quite pronounced.
 
Strange, I have never noticed a differential wear issue after pitting, my tyre wear is always the same and all the races I have run on racing hard tyres...maybe to do with running a 4WD on most of them and the RB Junior (I was being lazy) on Spa and Sarthe. The one strange thing I found at Spa with regards to tyres is that the Intermediate tyres were faster than Racing Hard tyres in 100% dry conditions (I set my fastest lap using inters)....I'm assuming that is related to the wet tyre bug rather than some peculiar characteristic of the RB Jr :confused:
 
There is definitely something fruity going on with the Super races after pitting. I have experienced the same problem of substantial tyre wear and increased lap times.

My theory is that the time is "warping" much like it did on GT5 - this affected online races where the lap time would say a much greater time than actually elapsed in real life when there was lots of cars near each other. I have saved a reply of when I did Silverstone where my second set of laps were consistently 3 to 4 seconds slower for real time comparison - I just need to find a stop watch now! I think pitting, or even all the other cars pitting, is creating the same problem as in GT5.

I have also noticed that the sound of the tyres when accelerating down a straight seems louder on a second set and the car feels restrained to me. This leads me to believe that the timing is far more intrinsic to the physics of the game than I previously thought.

Distance = Speed x Time, so if the Distance is the same, but the time increases, then your speed must go down. This is forcing the car to go slower than it should. Hence increasing tyre wear, as your wheels are spinning, but the vehicle is not moving as fast as it would do normally. The effect on the time must be fairly small - say 1 minute is really only 59 seconds IRL, but clearly it is enough to cause noticable problems.

I hope the above makes sense!

Wow - never noticed this in the Le Mans 24m (God it's weird writing that) but I was driving the R92CP and mostly was worried about fuel consumption (3 laps on every stint using short shift, lift before braking, etc). I didn't notice lap times doing anything crazy but it was wet and dark and I put the rest down to the economy racing. I was also avoiding making the tires noisy... Ran 3:40ish for 6 laps and was just able to pit on lap 6 (didn't know if the others would finish just after 24 or before), and then go all-out for one lap to win. I had forgotten that if they finish while you're still running, even if you're technically ahead you drop through the order until finishing your lap (when you suddenly pop back to the top). Anyway for me, the rear tires wore a lot faster all race; after 3 laps they were at 5 5 while the fronts were at 8 or maybe 7? Seemed about right in a powerful Group C car.
 
Hi all,

In v1.03 i did some testing concerning the consequences of making a pitstop. You can read it below.
There can be no discussion on this bug, it exists and its really amateuristic by PD and Kaz.

I just did the Same test in 1.04 and can confirm the Same issues still exist in 1.04.



I've posted my findings already in another topic and i want to share my info with you guys as well.

I did some testing with a Friend and its really weird how lap Times change after performing a pitstop.
We are both experienced drivers and the following was concluded.

The test contains 4 cars (all gt300 and specific specs) which we drove for 6laps on racing normal tires.
Then we made a pitstop to fill the tank and get new racing normal tyres which we ran for 6 Laps again.
The track we drove was fuji GT with tirewear normal and no aids except ABS.

I tested the

- celica (Fr car): 1st stint 1.37.0 fastest and average 1.37 low/ 2nd stint 1.39.5 fastest and average 1.40 low

- subaru impreza '06 (4wd): 1st stint 38.2 fastest and average 38 mid/ 2nd stint 39.4 fastest and average 40 low

- re RX-7 '06 (Fr): 1st stint 37.6 fastest and average 37 high/ 2nd stint 39.4 fastest and average 40 low

- lexus is350 (mr): 1st stint 38.6 fastest and average 38 high/ 2nd stint 40.3 fastest and average 40 high

My friend tested

- lexus is350 (mr): 1st stint 37.1 fastest and average 37 low/ 2nd stint 39.4 fastest and average 40 low

- Re RX-7 '06 (fr): 1st stint 37.3 fastest and average 37 high/ 2nd stint 39.5 fastest and average 40 low

We also experienced the same issues in an event online when we drove the BMW gt2 base model for about 50 Laps on silverstone. Lap Times dropped about 2 to 3,5 seconds depending on the driver and their setup.

Tire wear and tire squeeling is also higher than before the pitstop.

I hope PD fixes this quickly and not only me i'm sure!
 
I agree that there is something weird with the tyre wear. Even if you run the second stint with less fuel, tyre wear seems to happen at an accelerated pace compared to the first stint.

Luckily, this didn't stop me winning these races.

100% certain of the weird tire issues now. I just ran the 787B in the 24m of Le Mans again. Here's what I experienced:

Start: Intermediate tires, 60% water. Water stayed above 30%, zero tire wear or negligible. Fuel wasn't much of a concern, barely did any eco driving and was just getting in the red when pitting.
Lap 1 3:36.9, Lap 2 3:38.1, Lap 3 (in) 3:42.8.

Pitted for fuel and tires, RH and full tank. Track is now at 0% water and more or less stayed there.
Lap 4 (out) 4:28.0, Lap 5 3:42.9, Lap 6 (in) 3:56.2, tires wore down to 9 9, 4 5.

Pitted again for fuel and tires, still dry, RH. Didn't catch the wear at the end.
Lap 7 (out) 4:14.3.

So even factoring in the night driving and differences in wear, there's no way a dry lap on slicks should be nearly 5 seconds slower than a wet lap on inters. And a dry out lap shouldn't vary by 14 seconds from night to day.
