For this latest test, I've updated the mod with:

- 3 tire variations from the original A model that most people gave positive feedback. A1 is the original model A from Tuesday. A2 has the ultrasoft, soft, and medium variations of Model A. A3 has the ultrasoft, soft, and hard variations of model A just to differentiate them more.

- A new model B that's not related to A or B from Tuesday but worth the try.

Sean suggested to have the rubber static and avoid build up during the session. I followed his idea so that we have fewer factors influencing the test.

I'll leave the server up maybe a few more days. I'm also still waiting for the people from GPVWC to release the Montreal track.

Here is my report: I used same setup for all tests, and 122L to start. I pushed pretty hard all runs and wasn't trying to save any tire.

A1 Soft - Slowest Soft tire, but lasts 14 laps until 35% remaining
A2 Soft- Middle Soft tire, lasts 12 laps until 35% remaining
A3 Soft- Fastest Soft tire, last 10 laps until 35% remaining (old tires would last about 8 for me)

A1 Medium - avg is .1 faster than A1 Soft 18 Laps until 35% remaining
A2 Medium - avg is .17 faster than A2 Soft 18 Laps until 35% remaining
A3 Medium - avg is .7 slower than A3 Soft 20 Laps until 35% remaining

A1 Hard- avg is .4 slower than A1 Medium 28 laps until 35% remaining
A2 Hard- avg is .3 slower than A2 Medium 20 laps until 35% remaining
A3 Hard - avg is .1 faster than A3 Medium 28 laps until 35% remaining

My suggestion would be A3 SOFT, A2 MEDIUM, A1 HARD

A3 SOFT is .5 faster than A2 MEDIUM which is .25 faster than A1 HARD

These are from my tests. Others might have different data.

I would ideally like to see the Soft tire 1 second faster than Medium and 1.5 seconds faster than the HARD.

Nice work, Sean.

You're fast. I've only just now gotten through the A(1)'s.......

Thanks much.

The Williams F1 Racing team was busy at work today at the Barcelona's official tire test and these are the conclusions the engineers came up with:

A1 - Probably has the best hard tire of all the sets but all of the compounds have very little degradation, can run qualy laps for the entire race and probably make it in 1 stop. On this track that's very unrealistic.

A2 - Our driver pushed the tires very hard, degradation was at more realistic levels than A1, possible to make it a 2-stop race pushing hard but not qualifying all the way.

A3 - Very similar to A1 in the sense of very low degradation on the hard tire. Due to the 2-step difference in compounds, this maybe the set that makes the most sense.


In all seriousness, we all hate the current tires but I believe they are making for good, more realistic racing up and down the grid. People just can't go balls out on them. Yes, I know the Mediums are horrible and you can't use the Hards but due to that is why we all behave when running the softs so we don't have to use those other ones.

I am concerned that giving more tire to play with to some of the hot lappers we have in this league is only going to spell disaster. I can see Thursday's becoming a Tuesday night mini-f*****g race and people around this league know how much I love those :-)
To finish first, you first have to finish!

Can we also agree that 5 stops in Barcelona is also not good either?

If you were to pick from A1 to A3, which one do you think is the best going forward?

I tried messing with the wear rate before releasing this update but it did nothing. My options are being limited to picking from what's available and maybe do a mix.

From the 6 races we have done I can tell there's a lot of frustration throughout the field with the tires and I'm hoping that didn't affect the league negatively.

I wish we could have a happy medium between what we have right now and perhaps A3 but apparently it's quite difficult to get right...

I forgot to mention that all the tires actually HAD grip, not like current Med which after 3 laps start getting slippery, which makes for more crashes. (see Me at Monaco)

I think qual type laps on SOFT should only last 6-10 laps (12-18 if you manage) and Medium tires should be slower by at least .750, or you will just have everyone on Mediums like we have now on SOFT tires. The Hard tires should be 0.25 to 0.5 slower than the Mediums. Other wise you are not going to get any strategy, and everyone will pile on one tire again. These are all my opinions.

I don't mind the tires we have now. Either.

Yeah but I can't just make a tire slower or faster. Like I said, I can only pick from a tire that we have. So from all the ones we have tested, which one you think would get closest to the outcome that you want?

Thank you all for your feedback. I will be posting the next version of the mod today along with Canada. The new tires will be based on:

A3: Soft
A2: Medium
A1: Hard

Sorry for a late reply. I like the A1 compound. I did 16 laps on 120 ltrs with the softs which was almost double what I could do for the race. The A3 were similar but didn't last as long. The A2 I didn't like as soon as they were on the car. Felt much different from the other 2 compounds.
