I did. And in fact it says 35 psi and 60 for the spare.

I wonder why it is different.

Maybe for Canada, but I can't see why.

In any rate.....increasing his pressure a bit might help....

I wonder how many other members have different psi rating on the door jamb sticker???

 

Mine is from Canada too.

 

17" call for 35 psi, that's what mine call for, according to the door jam.

Maybe the 16" use 30 psi

 

Door sticker says 30 (front/rear) and 60 (compact spare), but I treat as minimum and seems like "check tire pressure" comes too often then... like more solid ride anyway. Keeping it at least at 34 (cold in driveway). Weather/temp varies here from one day to the next that (even at 34) I have to add air on really cold mornings in the fall still! I haul plenty of extra weight (a lot of tools for job) and never have seen 22MPG unless I have been hauling my little trailer too heavy for too long... My combined is usually 26-28MPG and I really am not nice to my little "Toolbox" at all. I have 125K miles on it and even kept the snows with a 97 load rating on since last year and have done pretty well. Hope you figure it out but really think tire pressure at 30 isn't helping for starters because that is a bunch of extra drag for such a light car. I know I can tell the difference when the tires get down to 30!

 

Thanks for your input guys, I am still unsure of what the issue is but I appreciate the help. My tire pressure is stable, and this is the third winter I've had this car so I doubt winter blend fuel is the issue. Perhaps it is a collection of maladies all coming to a head, either way it is more of an annoyance than anything else.

 

That must be it.....although, I still don't see why.....maybe to stiffen the shorter sidewall of the 17's...

 

Yes that would be the reason.

 

Driving technique has a lot to do with MPG. My long term MPG (103,000+ miles) is running at 30.4 mpg overall. I changed tires out at 92,000 miles and noticed a drop of about 3 mpg. I upped the tire pressure and it did go up a bit. (The last 10,000 mile my MPG is running 28+) The old tires were low rolling tires. I had gotten as high as 38 mpg during some road trips with those tires.
