Do you mean to enter and to exit just clicking no change tires and no fuel?
Never thought that this could be a possibility.

So do you mean to do a “fake” pit stop just after the first lap and the to run all the race alone?
It sound interesting…



Thanks for your comment so I can start evaluating if it is feasible for me.

Yep, pretty much. Just select no tire and no fuel; your car will come to a stop, then go.

Doing some more laps, and am really liking the Citroen around this track. Was able to dip into the 12s race pace. Should be able to get a better idea soon on whether or not getting tires is an advantage as I now feel pretty comfortable with the track.

I did one run taking tires on lap 12 (meant to on 11 but forgot lol) and it was an extra 4.1" to add the tires. Thus, the new tires needs to be worth ~.340"/lap - presuming no traffic - make them worth it. I think it's going to be very close, at least on the Citroen. Some Manus' cars that eat tires quicker (or more unevenly (think FF)) might not have much a choice but to take new rubber.

Jumped on my AO account (Honda) and when entering the oval while in S1 the car goes bonkers and spins. You can't re-enter the oval there on the normal racing line, rather you have to take a tighter radius thru T1 kinda dive bomb it so you can hit it at a straight angle or the car is toast. Not sure if you guys are seeing this with your Manu cars but heads up. The Citreon has no problem taking a wider line/radius in that area.

I've been doing some testing to figure out whether it better (or worse) to change tires for Rd.5 in the cars that I'm driving this season: Ford and Subaru.

To test it out, I did two 23-lap races in each car. In the first, I changed tires. In second, I left the old ones on. To keep things simple, I pitted at the end of lap 11 in every race. Why then? Because it is in the middle, which is optimal for the tire-change strategy. I chose to put the longer stint at the end when tire wear will be less from carrying less fuel weight. Of course, for the no-change strategy, it doesn't matter when the pit happens, so putting it at the same time as the tire-change strategy makes it easier to compare.

Here are the results:

Manufacturer	Model	Strategy	Opt time	Best time	Avg time	Total time
Subaru	WRX Gr.4	Tire change	1:14.421​	1:14.648​	1:16.464​	29:18.672​
Subaru	WRX Gr.4	No change	1:14.929​	1:14.912​	1:17.176​	29:35.049​
Ford	Mustang Gr.4	Tire change	1:14.695​	1:14.957​	1:16.622​	29:22.303​
Ford	Mustang Gr.4	No change	1:14.734​	1:14.984​	1:16.674​	29:23.504​

Tire tread levels at pit:

Manufacturer	Model	Strategy	Front left	Front right	Rear left	Rear right
Subaru	WRX Gr.4	Tire change	85%​	45%​	95%​	90%​
Subaru	WRX Gr.4	No change	85%​	50%​	95%​	90%​
Ford	Mustang Gr.4	Tire change	90%​	70%​	95%​	85%​
Ford	Mustang Gr.4	No change	85%​	65%​	90%​	85%​

Tire tread levels a finish:

Manufacturer	Model	Strategy	Front left	Front right	Rear left	Rear right
Subaru	WRX Gr.4	Tire change	80%​	45%​	95%​	85%​
Subaru	WRX Gr.4	No change	65%​	0%​	85%​	75%​
Ford	Mustang Gr.4	Tire change	85%​	60%​	95%​	85%​
Ford	Mustang Gr.4	No change	70%​	15%​	85%​	70%​

Conclusions and observations:

1. Obviously, I'm going to have to change tires in the Subaru.
2. In the Ford, the difference is less pronounced, but changing tires is looking like it would be faster for me, so I'll probably do that.
3. It feels like whether a no-change stop is viable is going to depend a lot on what car you're driving and how good you are at tire saving. Enjoy doing your own tests.

From what I can see from the total race time it looks like the tire change might be quicker if we push nonstop and change halfway then trying to save them for only a few seconds save at the pits.
Of course I’ll have to try from my side since the cayman is mid engine and rear wheel drive compared to your WRX and mustang but it does give me a good global idea.
Thanks you for that data

Thanks for all your posts about strategy. I've made a clear decision to change tires, as I'm also terrible at saving tires and don't have a high DR, which means I make more mistakes, and fresh tires will be more forgiving, whereas worn tires require maximum error-free driving. I think in this case, it's not necessary to have a strategy for when to change tires; just wait for the right moment to undercut.

I'm really looking forward to the race in the deep forest. I haven't competed in many championships, and this will be my first race where I'll be able to adjust the suspension and differential. I've always grumbled about not being able to change these parameters (and aerodynamics, for that matter), because in real racing, they're incredibly important.
