Hi, I just bought a 2011 GLK 350 AMG PKG and I'm very happy with it. Soon I will be needing tires and I was wondering if I can step up to 275/40/20 vs the factory size 235/45/20.


Also will I get a ABS, ESP or any error message on the display because of the different tire size?


Any help is greatly appreciated.




Thank you.

 

If you don't mind spending money on new rims that are wider and have different offsets to clear the suspension and furthermore have your tires poke out past your fenders, then yes.

If you are talking about putting 275s on the OEM rims, then no. With an 8" wide rim, a 235-width tire is about as wide as you want to go.
