now we only can set the tire changh by the tire weare, it is not easy to know how much wear it is & can't make a ploy very well.
can it changh to set which tires I would like to changh?

Scania, you have made over 70 improvement suggestions, but have yet failed to read the sticky?

http://upload.lfsmanual.net/images/9/9f/TyreExplanation.jpg <--- don't get what You exacly mean :P. But i'll post this picture though.

Havent seen that picture before but i knew it anyway

I guess he is about to change only front or rear tires, without change of compound.
Now we can do this only by matching 'change by percentage wear-out' setting.

It should be easier to do by hitting Enter on front/rear tire section in F12 menu.

Yeah, the different compounds has been suggested but this got me thinking when he said the percent wear...I know the F9 view allows you to see the temps, pressures, and the tire thicknesses, but what about a visual that shows the percent wear with and actual number? It's rather hard to tell the difference in thickness by just a little image. It'd be easier to judge when to pit also whilst racing so that you don't over run your tires and blow one out and to limit the number of pit stops you take.

While I agree with you that it would be easy if there was a display that said "xx% wear", think about what real life racers have. Nothing but the feedback they get from the car, and maybe the look of the front tyres in open wheelers. Netkar Pro simulates this very well, ie. there is no gauge whatsoever for tyre information while you're on the track. You do see the tyre surface changing over time as the wear increases, though.

So yeah... I'm not sure if a "percentage wear" indication would be a good addition or not. Definitely not realistic.

As for the OP's suggestion, we really should be able to choose which tyres need changing by just selecting "right front, right rear" or something But has been suggested before.

I'd love to know the temperature of my tyres surface live, the temperature of the air, the temperature of the sidewalls, the amount of dirt on the tyres and the wear in nice digital numbers.

Unfortunately you don't get that in real life. It's one area where LFS racers have life so, so easy in comparison. Admittedly, you can't examine the tyres carefully in LFS, but that doesn't show much anyway unless you're an experienced tyre technician.

You can force LFS to change tyres in the live menus. It will also happily change the compound of the tyre too.

Thus this suggestion is already implemented, pretty much. Once F9/10 is removed completely too, it'll be even better.

How about not removing it completely? Option in server config to block this menus in race should be ok.

I doubt anyone does it in real races, but in road cars we could set wear in mm's when we want to change the tire, with measuring in pits, which take some time.

Yes, but what you can't do is say "change the front left tyre and leave the rest alone". And that is something that a driver in real life can tell his pitcrew.

But it's pretty rare, unless the setup or driver is very poor. And LFS can do that, if you look at the real time display or you've done the requisite testing beforehand.

I'm not saying it's perfect, but it's certainly not bad enough to warrant a complaint.

1 tire to be changed is either flatspot(das driver) or oval racing(no comment). But for endurance racing, where you might need different compounds, it would be useful to keep a set and change the other.

The 1 tyre example was only an example. My point is that it's currently not possible to easily specify which tyres you want changed and which you do not want changed. The reason for wanting to change a specific tyre is irrelevant IMO. It should be easily selectable, end of.

in gp2, they only changh rear tire.....
and then, do you think 12sec to changh 4tires is little bit slow?

You can tell when you need to change tyres on LFS from experience.
The change at xx% wear is fine with me, although I'd like the option to choose whether I want to change front AND rear, or just front OR just rear, as obsolum/whoever else said.
