Tomorrow I'm putting on 2009 4S 235/35/29 and 305/30/19 Carrera II wheels on my 2009 base c2 coupe. What tire pressure should i inflate my tires to?

 

I run 40f and 44r

 

isn't that too much?

 

dksu, your manual will have pressures for 19" tires. They are 34 front and 37 rear for a 2009 C4S.

Sharkey were did you get those pressure numbers?!?!?!

 

I have 37 F and 44 R as a maximum pressure for my car (according to the sticker on the inside of the door), I run 34 F and 40 R on mine.

 

Just look in the owners manual...ALL THE TIRE PSI INFO IS RIGHT THERE!

NorthVan...just so you know and since I know you do not have the 09 owners manual...for 2009 the inflation is 1psi more than the 2005-08 C2S:

2005-08 33F 39R
2009 34F 40R

Also in the 2009 owners manual the inflation for a C4S is different than a C2S. C4S is 34F 37R.

 

Mike, I don't have a 09 (car or manual), but I seem to be running the same pressure that they recommend for the 09's in my 06.
