burning smell in snow

Hi:

Last night I was driving in snow with the traction control on. I notice that if the rear wheel spins, or fish tailing, while I was reving the engine, there is a strong burning smell even without the window open. It smells like something is super super hot, metal or rubber I can't tell.

Does anyone know what it is? Thanks
Nick

So, your driving, and the back wheel loses traction and starts spinning, and smell burning rubber?
i may not be looking far enough into this, but are you smelling the tire?

Do you have any idea where the smell was coming from? Front, rear, left, right?

Thanks guys. I'm not sure where it came from as it came so quick and disappeared so quick... But I only smell it when the tire spun in snow, or fishtailed in snow. And the smell was gone after the rear tire got enough traction and started normal driving....

Will tire spin to smoke even on snow? The smell was like burning tree leaves.... This is of course not accurate as I was driving with all window closed.

Here is what I think. When I step on the gas, the rear tire spins. Then the traction control engages, trying to hold the wheel from spinning. Energy must build up in some parts and need to be dissipated.... Maybe this is reason...

The TCS simple cuts the power of the engine when it starts to feel the wheel spinning. It does not "hold-up" that power somewhere in the system.

yeah it just retards the timing and reduces throttle response temporarily

So.... what was the smell then? Burning tire? Or brakes?

My thoughts are that it was probably the tires or the differential getting hot. Open differentials can spin quite fast (twice as fast as the actually tires is when they lose traction) and that could heat up the gear oil and cause some of it to burn off.
I've smelled burning gear oil before and it is a nasty odor.

Thanks I'll keep an eye on the oil. But will tire smoke even when spin on snow?

They probably won't smoke per say but, you can definitely burn off rubber if you get them spinning for short time.

Last night I brought it out for a ride... Got stuck in snow once, and the tire spun and spun and spun.... with or without the traction control I didn't smell anything....... so maybe last time it's just the smell of burning tree leaves from outside....

You are burning up your rear brakes!!!!!! Good God. That smell was your rear pads burning up. Traction control applies the rear brakes to control slide and to avoid spinning. It works in conjunction with the ABS system. That's why if you don't have ABS, you don't have TC......
