I went an extra 10 lbs to see if I could squeeze out better mpg. It helped a little but the wife came home and said something seems wrong with the car,she said it rides rough and clunky. we just went on a 150 mi trip over some poor roads and I noticed everything in the glove boxs was ratteling and the car felt like I was driving down the railroad tracks. lots of vibrations and a harsh feeling in the stering wheel. It was not a good idea.....joe -PS.Its been cold here in MN. the shocks and strut oil could be stiff too

 

I have my tires at 40psi and although I can feel a slight difference, it is not uncomfortable at all.

 

Not to mention the extra wear and tear on your front end components.

 

Two questions for you:

1. Do you have Michelin tires?
2. What pressure did you go to when you had the rough ride?

 

Michelin@42 psi That is what they read now and its about 20 degrees out I had put 50 psi in when it was really bad

 

What other tires come on the camry???

 

"Search" and you'll find several pertinent threads, incl. SEVERAL discussions on tire pressure... (it's been discussed at length yet apparently continues to be a hot topic).

Here are 2 samples about the types of tires:

Thanks HYBRIDFAN I NEVER LOOKED AT THOSE POSTS BEFORE. Now I will try running 38 psi on the michelins..

 

I assume you also looked into all the other "tire pressure" threads before deciding on your psi preference, as in for example:
https://www.greenhybrid.com/discuss/...ad.php?t=10062
and
https://www.greenhybrid.com/discuss/...ad.php?t=10307

For other folks, however: I certainly do NOT intend my post to spawn yet another long drawn-out discussion about what psi is "right" (we have enough of those on this forum already, thank you), but some of our forum members may be new and may not know about the valuable info already available just by doing a search on "tire pressure"...

'Nuff Said.

 

As an aside, tire gauges can be off by quite a bit. My previous cheap tire gauge read 4-5 psi higher than the Accutire Racing Gauge I recently acquired. Its appeal was that it locks onto the valve very well w/o leaking. No more press on, wait for the hiss, hope the hiss stops, and then hope it got enough air that it's not reading low. Also, it has a bleed valve so you can pump it up slightly hire than your target pressure and then bleed it down to the pressure you want.
