. p.s skip to last 2 laps i only noticed on last lap

I don't see anything wrong, at least, not with lfs.

my tyre exploded when i went round a corner

Yes,this is normal! In LFS it's pretty constant - if you reach 200°C,the tyre will blow. You should learn to drive without overheating tyres so much and monitor the temperature. Might be also useful to use harder compound,like R3 or even R4.

Defo not, tyres not explode at irl. i think it is a bug . plis remove to other section..

You were overheating and flatspotting the fronts consistently, so no wonder it popped that quickly.
