I think that tires in LFS shouldn't warm so fast, also it would be good to make tire wearing a little bit more noticeable.
In the other hand playing in others sims i notice that car usually have that soap tires after few laps (if soft tires are chosen) so cant say it different than in LFS.
Ofcourse i find it weird that new tires are wasted after a few laps it should last longer even if its soft.
Also when racing on Aston grand prix in multiplayer after 4 lap my tires where noticebly soapy, the car where unresponsive and braking was terrible but only when i almost took the whole lead pack in acident i notice that one of my tire blow up somewhere during race and i even didnt notice it, I think in real life it would be more noticeble.
On replay it appear that I drive with 3 tires for onle lap without even noticing it.
In any case 4 lap even if my drive style whas crappy (and it was) but still tyres should last longer.
Anyway I wonder how much things would be fixed in update, I mean the devs spend some time on it i am sure there will be some major improvment in physics and watching history devs tryed to make LFS more realistic all the time and actually listen to improvment sugested by users and since its not a new sugestion so.
