Can you help me figure out the correct tire pressures for my AMG GT Black Series (for street driving)? It has the original tires from the factory on it (Michelin Pilot Sport Cup 2 R tires).
The sticker in the door says 36 psi Front and 44 psi Rear. The sticker on the inside of the gas cap says the same for speeds of zero up to 202 mph. But, it says only 31 psi for Front and Rear for speeds of up to 155 mph. My dealer said to use the 31 psi for all tires. But, when I did that, the dashboard indicated low tire pressure warnings for all the tires.
What tire pressures do you use? Do you get any low tire pressure warning lights in the dashboard?

Thank you!
He or you have to reaset the paramiters for the tire pressures. 32 lbs cold all around works.
With all AMGs, the fuel door sticker has the right pressures. The lower pressure is known as the normal load pressure. That's what you should use just driving around by yourself on the street and not faster than 155 mph for extended periods. Then after you adjust them, you obviously have to store them as the new reference pressures for TPMS, otherwise you get a TPMS low pressure warning.
31 psi is also the recommended street pressure for the GTR.
I drove all the time on the street at 29 psi as it helped compliance significantly. Just reset the TPMS system when you’ve dropped the pressure, and the system will use that pressure as the new normal.
Btw: even with an aggressive street/track alignment and at 29 psi I experienced no untoward tyre degradation, and they wore uniformly across the carcass.
And, only slightly off topic, I've made the following calculator available to help compute your initial cold tire pressures when you go to the track: http://car.dnsalias.com/car/startingTirePressures.jsp
Documentation links are at the top of the page.
Note: that's HTTP, not HTTPS (for complicated technical reasons). The calculator is written in javascript so you can look at the page source to see what it does (if you're so inclined) and the only accesses are to load the page, after which the page runs independently so you don't need internet access to use it after the page is loaded.

This runs on my server that also hosts a security product. As a result, that server is constantly being attacked from a minimum of about 100 to a high of over 1K IPs each and every day. As such, I run daily security audits and block IPs with some fairly aggressive rules. One of the rules is that if the server is attacked from X number of IPs within a /24 (IPv4) subnet (group of 256 IPs), I block that entire /24 subnet.
So if you're with an ISP that tends to harbor (i.e., not get rid of reported) spammers 'n hackers, you can end up blocked because you're "in a bad neighborhood" (so to speak). If you PM me your IP, I can check and whiltelist you (unless your system is compromised and _is_ one that's running attacks ... which is how a large percentage of the attacks are actually run). You can determine your outgoing IP via: http://checkip.dyndns.com/
Again, off-topic for this thread (sorry) ... but multiple people have told me that they find the calculator useful, "so there's that."
Sell the car and buy a pinto where you don't have to worry about tire pressures. If you can't be bothered to read the owner's manual your pretty lame and shouldn't be driving anything worth over 500.00.....
