I was wondering if anyone has put any work into this? Either by practice/testing or a race in the endurance series?

Now we have a moisture indicator for the track do we know when the cross-over points for the tyres are? How do we know we're on the correct tyres at the correct times... ???

e.g.

Slicks maybe the best choice for moisture levels 0%---20%, thereby Inters become the best choice for lap times. Then maybe from +70% wets thereby become the quickest tyres...

Has anyone experienced anything that may benefit the community?
 
I don't have any figures to back this statement up or anything, but during the 1000km Suzuka event, when it first began to rain, I made (what I thought was) the logical choice to pit and put Rain tires on. Big mistake! I anticipated a change in driving dynamic but not as much of a change that I saw. After a couple miserable laps I decided to throw on some Intermediates and see what would happen. I'll cut to the chase and say that I kept Inters on until the track dried significantly (half an hour before I crossed the finish line) and put Softs back on for the remainder. I haven't bothered to use Rains since.
 
Only done a few races so far with the new indicator. Depending on how warm your slick tires are, you can run to approx 30% before you really must pit.

The lap times between slick and inters aren't too far apart between 20-30% depending on track/lap length etc. You can then run inters rights up to about 80%.

70% is when you can safely put wets on, but there is a good crossover area that the inters still perform well in.

I have only gone from dry to wet, so I don't know how the crossover goes as you head back down the %. I would imagine you could run down to 60% on rain tires, then probably closer to 10% for slicks...but as I said, yet to test...

I would take that as a rough guide for a start. The weather is random and I don't think there is a solid % where you should be on one tire over another. Take every race with changeable weather as a new experience and only use the numbers as a rough guide, lap times and how the car feels each corner is your best judgement for when to change tires, the % indicator just makes it a bit easier.
 
Well it depends i was thinking the same thing.

<25% slicks
25~60% inters.(slicks possible on racing line at 35%)
60>% wets
 
I had heard that 60% was the point to change to Wets, I did pit-in at 60% in a race last night against another player who was on comparable lap times to me (when we were both on inters) who stayed out on inters.

Initially at 60% I lost a small amount of time, it wasn't until over 70% that I was on the same pace each sector and over 75% ~ 80% before I was just starting to pull him in by a few tenths a sector, the race ended soon after.

I pitted in at 58%, came out on 60%. First split I was ~33seconds behind. End of first lap had dropped to ~35seconds behind. By the end of the race, I had clawed it back to just on 30seconds, the leader was saying last lap as it neared 80% was getting difficult and he missed a few apexes. Based on this knowledge, I would hold off to closer to 80% to go onto full wets. I understand it can rain harder and the % can climb faster than 10% per lap, so it will just depend on the situation and weather at the given time.

My experience is based on Spa only so far.
 
I was just wondering what type of grip settings are default in GT Life races? Standard of Realistic? We seem to only have a choice in Practice and Arcade Mode. I wonder why...

The grip reduction is set to low in a-spec so racing softs are the grippiest tires in all situations. The rain tires only matter if you play with grip reduction set to real and that is unfortunately impossible in a-spec races.
 
This really sucks. Are there any plans to change that? I don't like the idea of realistic racing only during Arcade and Online events :/
 
Haven't heard about it and it isn't much talked about either. People are propably mostly thinking about online. On a positive note the AI is using the proper tires so you can use them too to get a more realistic experience regardless (if only AI was better in rain though).
 
A significant amount of this is to do with the downforce on your car, I drove the new Impreza TC around Spa, was 40-50% before I needed inters, and then 75% for wets. A friend of mine did manage to use the softs to 100% though (and posted competitive lap times!)
 
I dont put inters on till 70% and wets at 100% keep your slicks warm and use RA function to alter TC as required.

TC= :yuck: Very Yucky word.

Slicks work up to about 10% On real track grip, 25% maybe with low grip setting. Inters up until about 60% real, Roughly 70-75% low, Provided you stick to the racing line though. If you dont, You'll have next to no grip (Real track grip)
 
It actually depends on driver. I like to keep my slicks on til 50% sometimes. It's all about handling the car and seeing what you can do. But I think inters at 40% sounds good, and full wets at about 70%

I thought you wanted to avoid the groove when the track was wet. Sure seemed to help in the AMG event, but I don't know what the grip setting for that is and it is on comforts. I haven't done too much serious testing in the rain outside of that.
 
I'm currently running the Le Mans 24h and have some interesting findings (low grip, not real, as a-spec). Using the Mazda Furai Concept

N.B. I am using SRF (wait for the condemnation), so this is probably also a factor.

Racing Softs are the fastest tyre i've used, even with 100% surface water. They lose approx. 15 secs a lap in 100% surface water versus 0% surface water

Racing Wets are on average 10 secs a lap slower than RS (100% surface water), and have more degredation towards the end of the stint. Both Wet and Soft tyres outlast the fuel with 100% surface water.

I haven't yet tested with Racing Intermediates, but will do so if the Surface Water remains at 100%, and i'll update on findings.

An interesting note, I was still able to maintain the same lap times as 0% surface water, until it reached 40% surface water. At that point the lap times worsened, but it is hard to determine precisely how fast this occurs using this method of testing as the track surface water is constantly changing, and it's not possible to determine an average lap at any one point except towards the extremes (0% and 100%).
 
Update:

Still running the same race with the same car.

Tested on Racing Intermediates, still 100% surface water. My average lap times are very similar in these conditions as with Racing Softs!

I can't say this was expected, but it's certainly interesting. Given these findings I may also test with different dry tyre compounds if anyone is interested?
