I get it a bit in the wet, I just assume it's water and dirt on the hot exhaust.

Burning rubber smell? Or something else?

The rubber smell is standard.

Yep, rubber I assume are the exhaust hangers heating up.

I know the burning rubber smell is fine, but I don't know exactly what is burning (not heating).

I'm guessing it's tiny bits of rubber wearing off the tyres and sticking to the hot exhaust?

Anyone know for sure?

Mine too... it's a question that's come up a few times...

My favourite response plus explanation...

I had the burning rubber smell after long journey on my 987.1, mostly after long journeys. Never had a burning match smell though, on either the 987.1 or 987.2. I was concerned about the rubber smell and posted on PH to get a general opinion. It resulted in my favourite PH response of all time...

'That's the smell of 'awesome'.'

It turns out that the smell eventually dissipated and was more likely rubber dust from the tyres melting on the hot exhaust. Was still awesome though!

Roads have rough surfaces. If they didn't, how would you stop.

Tyres have slightly rough surfaces.

Tyre/road abrasion happens leaving dust to sink into the slight depressions in the road.

It rains bringing the dust to the surface,

Your tyres kick up water mixed with rubber dust.

The Kamm effect brings the mix back against the car. Sometime look at the back of a white wagon after a rain. That black dust shows the mix coming back at the car.

Some of that airborne mix comes back against hot exhaust parts.
