Tire Pressure
I have a 2001 S430 with 18" Lowenhart wheels and 245/45ZR18 96Y tires. My question is: since they are not original MB tires, should the tire pressure be same as listed on door. 29psi in the front and 32 psi in the rear. or different? I just bought this vehicle last month. So, I am still learning. Any sugestions, please.

That tire rating is the maximum recommended. Most authorities recommend following the manufacturer's recommendation. This is typically based on ride comfort, so if your priorities lie elsewhere...

BFGOODRICH g-Force T/A KDW tires
size: 245/45ZR18 96 Y
Max load 710 kg(1565 lbs)
Max Pressure 350 KPa (51 psi)
The car is driven usually on city roads and on interstate, roughly 50 miles a day with an average speed of 50 mph.

Comfort: about 29-32 PSI cold all around
Mixture of comfort and economy: about 32-35 PSI
Economy: 37-42 PSI
Sport (for cornering) - about 40-45 rears, 35-40 fronts
Sport (for straightline runs/drag strip) - About 40-45 fronts, 20-25 rears
From your description of its daily use, I would probably go 33 all around or somewhere close.
You guys can chime in if you believe my pressures aren't exactly right.

Guys, sorry if this is off-topic, but it has been mentioned in this post. Could anyone shed light as to why you would want different pressure in the front tires and back tires (ie. 29 psi in front and 32 psi in back).
I am still new to all of this and am trying to understand why this is the OEM recommended pressure.
Thanks a lot!
