Tire question

Tire question
During last fall I replaced my stock tires on my 504 edition with some Toyo Proxy Plus all seasons. The tires are great, but now that it is spring I see the tire pressure going up above 50 PSI, which is the max rating on the sidewall.
I went to the Toyo site and plugged in the information for my car: http://tirefinder.toyotires.com/?vid=52582
If you look at the pressure for the 507 Edition, they say 42 front and 46 rear. I haven't tried this yet, but it would definitely get the front pressure below 50 PSI and the rear considerably higher than the stock PSI.
So the question is, do people go with the tire manufacture recommended pressure for the car or do they stick the the MB recommended pressure for the car?

All tire manufactures are different,and recommend different pressures, when in doubt (if you using stock sizes go with the car manufactures recommendations), having said that on my 507 (stock tires) I go with 42 in the front, and 44 in the rears....best combo in my opinion (I've tried all different combinations).

IMO the MB recomendation is probably only useful when using stock sizes of mercedes labeled (OEM) tires. A different model tire, even in the same size has different properties and may require more or less pressure to acheive optimal grip. What is considered optimal grip is also dependent on what you are doing (drag racing, autocross, road racing, mud bogging).
Also I'm not sure how much the MB recomendation is designed for optimal grip vs fuel economy vs best ride, or the best comprimise of these.
Bottom line it's up to the driver to determine what the optimal pressure is to run in their tires.
