I have *6611 sticker on my gas door like guardian and decided to run front 36 and rear 35 on my oem 19" runflats in summer.

 

The *66 11 sticker looks like it is in the mix of part numbers for 2018 as well, but I've seen photos of fuel doors for the C450 that also match the *66 11 sticker's pressures, but are, of course, a different part number on the sticker. I've seen images for the C300 that match what's on *65 11 sticker.

 

haha what a mess! Just a thought to to add into the mix - wonder if it depends on which tire brand was provided with your build? I do have the Continentals - which seems to be the most popular.

 

I think I am gonna change to 37 front, 35 rear.

Holy sheet, I can't make up my mind, feel like I am that sticker.

 

These numbers are cold tire temps?

 

not going to lie but that indeed is interesting, I mean I seen 2020 sedans having the 42 front for 18s sticker (which matches my 2017 sedan) while the 2021 is back to the 36 front for the 18s.
