Hey guys,

On my 17 CTTS i have the 21" wheels with Michelin PS4S, Partial load and 2.7bar front and 3.0bar rear.
The ride is a little firmer and if i go to let's say 2.5bar all around pressure i can't store it, the dashboard won't let me.

Can you help me with an advice how to proceed? I am not that good at this stuff.

Many thanks

I run 40psi, or 2.7 all the way around. I inflate the rear if I load the car up with goods or is towing. 2.5bar may be a little low, does not give the side wall enough support and as you say, may be below what the car will allow. You can try winter tire setting at 2.5 and see if it will take it.

To clarify, do you have a Cayenne S or Turbo S? If turbo S you have air suspension so ride should be ok.
Next step is to replace your 21" with 20"
