WTH is it with the HHRs ????

About 2 weeks ago the turn signal just decided to quit canceling after turns in either directions, No issues whatsoever... just decided to quit canceling during a trip to the store and back.
Then the last 2 days showed my right rear tire was low ( little tire icon popped up on the dash ) so I checked and they were all on , just a few pounds low on the right rear by 2# so I topped them all back at 40 psi then tonight the right front popped up with RF-- but the tire looks fine as all the others did yesterday after I filled them.... all this little piddly crap is getting on my nerves, nothing wrong (well sort of ) but a light popping on here and there like the car is Retarded. Im about done with it, ready to sell and go back to 1950-1970 just a motor and trans without al the money grabbing government controllers. Anyone want a 2008 $2700
Runs and drives great, , no codes, just some anal tire sensors

When the tire sensors get towards end of their battery life, (life expectancy is + or - 10 years) they can read weird, one of mine read low, yet my tire digital gauge read spot on, w/cold tires.

You are putting 40 PSI in your tires ? Why ? The drivers door jamb sticker will give you the correct air pressure.

i go on the psi pressure on the tires. even the shops put them at 40 psi.

My winter tires say , max 50 PSI , I believe that’s to set the beads, not drive at that pressure, 35 psi is what my door sill placard reads.

RJ_RS_SS_350

The placard varies, some say 30, some 32, or 35. I wonder why? Maybe the aspect ratio of the original tires?

Oldblue

The 18’s on an SS say 32 psi
The 17’s on my LT say 35 psi
The 16’s on my LS say 35 psi

it probably is because of the aspect ratio

Radco

My 2011 says 30 PSI but when I had the snows put on they put in 35PSI . Still rides nice

The PSI on the tire is the max pressure. Since the tire fits probably at least 100's of different vehicles.. Each will likely vary.
The door card tells you what GM believes is optimal for the HHR. Many (not all) shops could care less what the "Correct PSI is for a particular vehicle. Just so it is full & can get out the door..

If one fills the tire to the Max PSI on the sidewall, & when that tire gets hot driving, it will be over the tire Mfgr's rated PSI.. Not an ideal situation..

This ^^^^
I have seen the tires on my SS start at 32 psi, then 100 miles down the interstate get up to 36 or 37.
The Cooper tires I put on my Dodge truck show 44 psi on the sidewall. The shop that mounted them filled them to the max. Rode harsh so I dropped them down to 35 and keep them there. (the placard in the door says 32 psi but that was for the OEM Michelins)
