When I got my 08 997TT, I had my detail guy remove all the decals from the door jams.

Unfortunately, one was the tire pressure sticker.

I got a low pressure warning (39 PSI) for the rear left.

What pressure should I have in the front and back tires. They are pirelli P zeros (Factory tires).

All the tire says on the sidewall is Max PSI 50.

Thanks

 

I run 43 rears and 38 fronts.

 

37 front , 44 Rear

Get a nitogen tank and regulator and hose on ebay is a option....

I paid :

75.00 for the N2 Tank 60 Cubic ft (New )

60.00 for the Nitrogen Reg 0 / 200 Psi( New )

5.00 for the coil Hose

12.50 for the filler with built in pressure gauge

15.00 at the local air supply hose for a nitrogen 65cubit ft tank / 1500 PSI

I rarely put nitrogen in the tires now, better for the tires since it's a dry fill, and pressure maintains what you put in since it doesnt expand with heat

Or you just go down to Big O tires and have them switch the air for N2 for you for 24.95 and get free Re-fills

Gee-Bee

 

Just got my TT coupe last week. It also came with Pirelli P Zeros. My door jamb sticker says cold inflation pressure is 37 psi-front, 44 psi-rear for fully loaded vehicle.

Owners Manual says 33-front/39-rear for partially loaded vehicle (up to 2 persons without luggage).

 

If you have aftermarket 20's what do you set the tire pressure to?

 

37/44 for me but with one caveat .
On my last car (a 997S ) the door jam number was different than the manual .

I adhere to the manual .

 

Good advice.

 

I have Bridgestones and like (cold) 33 front 37 rear.

 

Michelin Pilot Sport on mine. 37/44

 

38/44 hot

- note that you can adjust whether you are running partial or full load via the lower left column stalk (the one for the menus below the tach). If it is set of full load you may want to switch it to partial load unless the car is full of people and stuff.

 

I'm running 34/40 cold...

 

I have the same problem, I just need 0.3, so refilled it, anyhow now I'm having difficulties reseting it somehow.

 

Check the manual there are different pressures for different loads (people + luggage). PS2's - Have run mostly 33/39 cold = One person no luggage. Now running 36/42 cold.

 

Make sure you drive for a while in order for them to reset. Could take 10-20 miles or so, sometimes less.

 

Is this the same as a 996tt? Or is the tire pressure different for those?
