[R129 SL] sl500 proper tire pressure

[Jan Kuylaars]

It is indeed not fine to drive with higher pressure, but I have ruined 4
new tires last year because I had them to flat.
All tires become little cracks on the inner side of the tire, so you
even cannot see it.
*In Holland they have a lot off speed limit bulbs who are just touching
the inner side of the tire.
It is even dangerous, now I have no problems with 2.8 bar rear and 2.5
in front.

I know this sounds dumb, but I have heard all sorts of opinions about 
tire pressure on an sl500. I have Bridgestone Pole Potenzas Z rated 
that take a maximum of roughly 50 PSI. The Mercedes manual says 28 PSI 
is recommended. My M-B expert mechanic says this is too soft and 
recommended 35 to 40 PSI (the former for the front wheels the latter 
for the rear wheels), and yet another knowledgeable mechanic 
recommended low 40s PSI which gives the car a harsh ride in my opinion. 
I do not want to cause irregular or premature tire wear and would like 
to hear what you all like on your Z rated tires. Thanks, rt
