My 06 MCSa (new to me about 3 weeks) has a burning rubber smell when I park it in the garage. There is a nice corner about 1/4 mile from home that i tend to jump on, when I pull Mojo (mini's name) into the garage the rubber smell is pretty strong. I don't believe I am squeaking the tires on this corner.
I do not notice any belt squeak either.
anyone have an idea what I am lighting up.

 

How hot are the surfaces of your tires? I doubt it is them. Check under the hood around your coolent resevoir, is there any spilled on the outside of the tank or on the header heat sheild?

That is the only thing I've had that smells a bit like burning rubber.

 

maybe belt slippage?

 

i tent to drive mine a bit crazy sometimes on the way home... and when i park it in the garage i cant tell if its clutch, tires or something burning.. but its normal i think.. i have a 05.. and with all the mods on it.. its still normal ever since i bought the car.....

 

Road surface is cold at times slightly wet. One thing that does happen with the brisk acel is a marked hesitation before Mojo gets with it. This hestitation can occur when the engine is cool or hot but happens most usually with acel mostly on a turn even a slight turn. I tried the near home turn with the ASC off and the hesitation was not there that time (only tried it once) but the rubber smell was there. I don't know if the hesitation is somehow related to the rubber smell.....

 

i smell my tires all the time. eagle f1 gsd3s have a good smell

 

Mine will do a similar thing (05 S). I will do a somewhat speedy launch and it will get up to about 2.5k RPM fairly quick and then once it gets past that it just takes off, it actually jerks you back in the seat a little (it isnt a slow build). Why it does this is beyond me, I always thought that type of stuff was just an issue with turbo cars.
