I think it is 35 pounds of pressure in the winter and 32 in the summer.
If your Jetta came with 16 inch wheels as original equipment the correct tire pressure is located on a plaque mounted on the driver's side door post. If the 16 inch tires are not original to your car, the tire pressure on my 2007 jetta with 16 inch wheels is 34 pounds front and rear.
I have 18" wheels and i run my tires at 37 psi and it is perfect so try somewhere around that. It really matters what kind of tires you have. Look on your sidewall and see what the MAX psi is for each tire and fill them up about 85% of the max psi.
27 psi front ... 33 psi rear. OR Check the sticker either on the door pillar or on the drivers door itself (when opened).
