I am continually amazed that it there is such discrepancy within the supply/manufacturer to customer chain.

2012 GLK 350--AMG Package 20" Chromed Wheels, Loaded
AMG Air Pressure
I just picked up my fully loaded 2012 GLK-350 AMC package. I have the new 20-in wheels and wanted them chromed (looks awesome). The dealership had a new set of them chromed there and swithed them out--same wheel, just Chromed. My question is: since they are the 20-in wheel and tire and I don't believe they are listed on the door panel or fuel cover--and since I live in So California where the weather doesn't change much year round, does anyone know the exact recommended pressure for these 20-inch AMG wheels and tires? Thank you very much for any info you can provide--it seem some say 35 for all tires and some say different info. I'm just wondering what all of you out there are running yours at.
Lastly, can these tires be rotated? I've never been able to rotate any of my previous 5 E-Classes or my wife's C-classes.
Thx!

235/45-20 tires? If so, 33 front & rear light load. 35-39 front/rear max. load. Was your GLK built with 20" wheels? Chrome won't change the tire pressure.
Your standard 20" tires are either the Pirelli or the Dunlop at the bottom of this page.

ps: Look at the chart on the door pillar. The tire size listed is the size the car was built with. Same size tires can be swapped front to rear.

Yes. rotate them every 5-7.5k miles should be fine. The tires aren't staggered.

The Pirellis are almost 33% less.... ???? For summer rubber, I may get these placed on the car. These PZero's are not USA/Canada OEM models, but are now available in our 20" size.

Thanks guys! My bad! I actually just walked out and looked at the door panel and to my surprise, it actually has the psi pressure for the 20" wheels. 35 front/39 rear! and you are correct VENCHKA, they are Pirelli 235/45 R20's. Thanks everyone!

Remember what I said, air will expand 4 lbs.
You can see this on your COMAND dash monitor after only a couple miles of driving.
Go back to your fuel filler flap & use the in between light & heavy load (33-35) & you should be fine esp. since SoCal doesn't get much cold air to worry about pressure loss.

The new pressure gauges on the dash look cool but don't seem to be too accurate. I went by my local tire store and the tech put in 39lbs in the rears and 35lbs in the front. Done on a digital air machine that is 100% accurate. I drove out and they showed 35F/38R--15 mins later they showed 34/35F--37/38 R! 10 mins later they showed 34/35F--37/37R. So I'm not going to look at it anymore--LOL! I saved the 35F/38R as the marker on the system. Still amazed that with all the technology out there, this simple gauge doesn't work. Still thanks for all the much needed advice today! Best!

Could be, the Cowboys train across the street from my home!
the gauge shows 33/34 in front tires and 36/35 in back and keeps changing so my guess is the gauge in the car isn't too reliable.
