Okay, mabye a stupid question - but when I got my car back from the 7500 mile check-up, I think they must have put some more air in the tires because now I'm feeling every bump in the road. I remember a thread about lowering the PSI in the tires a bit to avoid this. What are suggestions for optimal PSI?
Thanks

 

spec is 33/33. You could try 31F 33R, if you want. But make sure first that they simply didn't overinflate them.

 

Yeah, they keep putting mine at 35f/r. The Bridgestones seem very sensative to psi. At 33 they are perfect, at 35 you feel the bumps in the road and the rear feels like it's going to break loose on rough pavement.

 

Thanks

 

So I went and bought a digital tire pressure gauge and all the tires were at 37 PSI!!! No wonder I was having a rough ride.

 

You think THAT was rough? My dealer inflated my tires to 47 PSI.
The real lesson here is that we ALL need to check our tires once we get our cars back home. You can't trust anyone these days.

 

After my last tire rotation, I went 2000 miles before I checked it, and all were at 41psi (supposed to be 30). After I reduced it, gas mileage dropped about 1-2 mpg.

 

I dunno... I keep my tires at 37. I like it kind of firm without being jarring.

 

make sure you are checking the pressure when tires are absolutely cold.... even a few miles driven can cause the tires to be warm enuf to mislead you. If i recall correctly, its 2 psi increase for every 10 degrees change in tire temprature.

 

I had my G in the shop about a week ago for it's 1st oil change. After reading this thread I went out and checked my tire pressure with a digital gauge. Sure enough, 36psi in all tires except the front left was at 30psi. Now that I think about it the car was pulling left a little.
I guess the tech had to take a smoke break while he was over inflating my tires.

I had them set to 31F/33R before the service, I guess I will be stopping at the station on my way to work tomorrow.
