The monroney sticker for my S580 says that it has foam filled noise control tires...I was surprised to realize yesterday for the first time that the wheels are not staggered, the 20 and 21 AMG sizes are staggered but not the 19s, where the 19" AMG wheels on my W222 were staggered. Looking around at tires to replace the runflats...it doesn't look like these tires are actually foam filled.

Has anybody dismounted these tires and seen for themselves if they are or not?

 

Just in case anybody else comes across this question, they are not foam filled despite what is on the monroney sticker
