As said above, the fuel door sticker is what you should use based on the load, speed and types of tires. The door jamb sticker corresponds to the last row above the M+S section. That's what's known as the max load pressure for the tires your car came with. You have different pressures on yours than my 2019. Might be because I have the lightweight 5-spoke AMG forged wheels. Those are super light. The ones most people option are heavier wheels. I run 33f and 32r as per the fuel door sticker for normal load and speeds up to 155 mph on 19/20" tires. Ran the higher pressure during my European Delivery trip when I was doing speeds above 155 mph, but eventually lowered them and just kept an eye on the tire temperature. For short bursts above 155 mph, the pressures don't really need to be increased. The ride quality gets pretty harsh at the higher pressures.

Be very careful. I bent 3 wheels with that PSI spec. I have the same RXC wheels as you, they bend very very easily. After I went to 42 PSI all around, no more bent wheels thankfully.

We've talked about that. Not made for bad roads, but no issues after 6 years as long as I don't drive through potholes. They don't bend any easier than past low profile performance wheels I had. You can make any wheel strong as heck, but then they'll also weigh a ton. If you have bad roads, then an SUV with lots of sidewall is probably the better choice of vehicle. I rather sacrifices a wheel than something else in the suspension, but obviously best is to not drive on crappy roads in the first place. If you hit something that bottoms out your suspension, something gotta give, and this car doesn't have a lot of suspension travel.

Its hard to avoid. I often drive all around the Bay area and can't avoid every single pothole or bad road unfortunately.
Time to move to Germany and enjoy the autobahn where potholes is not really a thing
Or in general, move to a milder and less wet climate, so the roads don't deteriorate as fast under extreme heat, humidity and annual rainfall. Florida is one of the wettest states. Almost double the average annual rainfall of Germany and more than double of what we get here in Cali. Consider a more suitable daily if you depend on a car to get around and keep the AMG for the nice roads. FWIW, neither I nor my wife daily drives and we have her car with 16" wheels that can take a beating if necessary.

For sure, definitely pick a place where road salt is not used and that roads can't expand then create a void. Avoidextreme cold places where sand is used instead of salt, that is not good for the vehicle as well re: sandblasting.

I was saying bay area as in the San Francisco Bay Area They've redone the 880 recently and that's where I bent all of my wheels. Potholes that I could never see or safely avoid are gone... for now.

Your profile says Florida, so that's what I was going with. I lived here for 25 years and never had an issue with a pothole on 880, but as said I don't daily drive. I mainly avoid 880 during the week because of all the semi trucks. I've cracked a few windshields on 880 due to rocks thrown up by them. The pavement on 880 was bad for while, though. I remember that. It was repaved a long time ago in the Oakland area, though, before I even got my current car. More recently further south in the Fremont/Union City area. I made the mistake driving there while it was ripped up and cracked a windshield again. So I avoided the area until they were done with repaving it. Now it's nice.
This is what I'm getting at, though. If you have to be on the road on the weekdays around here, this isn't the best car for it. Between dodging all the knuckleheads, the semi trucks everywhere and the commuter traffic there are better ways to get around. I live and spend most of my time in the Berkeley/Oakland area and only a 15 minute walk from the nearest BART station. Back in the days I commuted to SF by BART for 10 years. You couldn't pay me to drive and sit in traffic. I once had a commute down to Menlo Park. Worked on site at Intuit, but I quit after 6 months. They couldn't pay me enough to sit in traffic 2+ hours a day. What made it worse was that I had a manual transmission at the time. No fun in stop&go traffic.

Mercedes SLR McLaren 722 S Is Extremely Rare Example Modified by McLaren
Slideshow: A one-of-one U.S.-spec Mercedes-Benz SLR McLaren Roadster became even rarer after a factory-backed transformation at McLaren's headquarters.
