What Tire Pressure is Best?
Hi Guys, I have a 2018 S63 sedan. 44K miles.
What tire pressure are you guys running your cars at? I ask because mine are set to 49pis cold on all four tires. Some of the guys on the non-AMG forum suggest pressures closer to 33psi. My car runs perfectly, as far as I can tell, at the upper limit of suggeste psi. The car had barand new PS4's when I bought it last year, inflated to 49psi. Then when I replaced them with All-Season PS4's last november the tires shop inlated them to 49psi cold. They normally get to around 51psi to 52psi in daily driving during this past summer. I want the best handling and safety, not too concerned about safrificnign a little ride quality.
What are you guys doing??

Maybe I'll try low 40's, around 43psi, all around and see if that makes a difference. I checked the tires and don't see uneven wear. What psi are you running?

When I look at the label, it says higher pressures at higher speeds, kind of counterintuitive since the heat causes pressures to rise. I like the idea of 40psi, maybe I'll ratchet down to 44-45 first, then 40 after I get a feel for the first step.
I've dreamed of driving my S63 at a little under 150, but I've had dreams of not having any grey hair and going 160 in my 3000GT, and almost 190 in my XFR, but I was a kid when I dreamed that.
When you were dreaming about driving your car, what was the top speed you achieved...again, in your dreams, not real life.
