Jerking. Low fuel mileage clanking on 08 328xi coupe

Rishidhir · 02-03-2011, 12:29 AM

After overloaded my run flats noticed the car jerking and clanking noise in shifts (auto). Extremely low fuel mileage I used to get 420 km per tank now get 330. Any ideas

Fuel pump, maybe clogged fuel filter.

All started after I changes the tires to non rfts

Clanking and jerking? Doesnt sound like tires contributed to that. Sounds like a trans problem.

Do you change to a staggered setup?

I don't have staggered. 225 45r17 Michelin pilot a s plus.

Overloaded meant change over - it's the spell check on my iPhone.

It's not your tires, it's your trans.

Forgot to mention typically happens when it comes back to about second gear and I accelerate again.

Something is loose or broken, tires themselves should not be at fault but maybe something was done incorrectly or damaged while swapping them? Could be anything from wheel lug nuts not tight up the drive train to the tranny.
