Correct Tire pressure for Panamera GTS 20'
 

Does anyone knows what the correct tire pressure for Panamera OEM 20'in wheels? After i did the alignment, the car feel stiff and when the car goes on uneven pavement, the steering wheel goes little to the left and right, is this normal or too much air on tires. Thank you!

You should find this type of sticker on your Panamera frame when you open driver's door.

Yea, it was 41 front and 45 back for cold tires. But isn't that too much? It's 100 degree out now :( car feels very stiff even on comfort mode.

The sticker says that pressure is for 68 degrees. Anyhow You have to big pressure definitely, especially if you drive alone, and at 100 degrees plus after some driving it will go up, select and check that on TPMS

So what should I lower to? My car feel so stiff now :( and even pull alittle when come to a stop. Maybe they didn't do a good alignment I guess

What model Panamera?

Do you have..
Summer tires or All Season?

Do you want Comfort Pressure or Performance Pressures?

Are you carry full load of four passengers or partial load of something less?

What is the ambient temperature where you are located?

There are pressure charts for the combinations of these questions in your owner's manual.

I am in New York, all season tires with 2 passenger in comfort. Thanks

Sorry, it's GTS Model. Thanks again

I have the same setup? You need 36psi front and rear at 68 deg ambient. Now that temperature where I live is up to 90 deg, 38psi is the correct number. Always check the pressures when the tires are cold, before you start driving. I'll try to post the Porsche chart that shows the slight adjustment in cold inflation pressures at different ambient temps.

Every car I have owned that has had ultra wide tires will exhibit the left/right wander, especially on grooved concrete or well worn rutted asphalt. It is called tramming and is normal. Also soft snow tires will do it.

Just lower the pressure to 38 front and back, OMG! Big difference from 44 and 46. Car won't bounce as much anymore. Thank you all :)
