Tyre Pressures

MB recommend 29PSI all round for my W211 2005 220cdi. I found the above that recommends a bit more.

Until today I haven't yet checked/inflated them and to my horror they were showing 33psi and deflated to the 29psi I specified on the machine. 29PSI seems a tad low, and the car drove fine before. Should I go for the 32psi rear 30psi front as recommended.

Stick to what it says in the fuel filler flap for light load.
How warm were the tyres before adjustment, they may be under inflated now?

Each 10 degrees of temperature =0.1 Bar of additional pressure.

Its just me usually in the car. Alas today was quite warm and I'd been in the car c.1hr beforehand. I stopped for fuel and saw the air machine and thought as I put on 400 miles yesterday it would be a good idea to inflate.

They were not cold by any stretch of the imagination. They maybe underinflated now
