Re: What is the best tire pressure and why?
I changed the pressure in my '04 FWD CE to 40 per recommendations on this board, and wow! It's like a new car. Judging by how it feels behind the wheel, I would say there is less rolling resistance and quicker response to the steering wheel. I haven't measured yet but I know I'm also going to get better gas mileage, since the engine is not working as hard to propel the car. As a corollary to that, it accelerates more quickly and smoothly.
My only concern is, since there is less rolling resistance and quicker steering response, doesn't that mean it is not gripping the road as hard as before? Is that anything I should worry about? Just wondered if anyone else had tried 40 psi and had any safety issues, such as losing grip in the rain, etc.
However so far I am loving it. It just seems like the car is a lot happier now, like this is the way it was meant to run. Thanks to everyone who investigated tire pressure and took the time to share with the community!
