Pad-Tire Smell? Urgent

Today I did a nonsense in a snow covered place, I could not come out front, I had to try to go back. As a result, skidding flew in the air. Even while skidding, press the brake sign appeared. After a while, the fragrance started to come, but it was heavy. We finally got out. I used 6-7 km after exiting, there was no problem in gear shifts.

My question is,

This is the first time I have used this gearbox, how can I tell if the pressure pad is peeling off or about to peel off? Could the source of this smell be in the tire? (Tires Conti Ts850 snow tire)

Good forums for everyone.
