honestly I read it from this forum. And a couple spots on the net. What i talking about with tire pressure is in regards to my traction control. Alldata claims as well that mis-matched tires can carry different diameters and will set the esc light. Well with low tires you can get the same effect. Also there was multiple corrections on alldata stating is was fixed by air in tires.
Like I spoke above I'm following a flow chart and I'm not one to skip over any possibilities. I did just put tires to 35psi and reset the computer and so far zero codes except for cam solenoids. I'll take it for a drive to town later and see what happens.
I dont expect this to be the fix. But iv been wrong before.

 

Your SS calls for 32 psi, so the 30 psi was very close. Be careful overinflating like that. I left America's Tire one time, they had mistakenly inflated my tires to 37 PSI. It was a wild ride home... It wandered all over the road.

 

Check the door jamb sticker for the correct tire pressure, I believe it is 32 PSI on the SS with 18 inch rims

 

I really think your splitting hairs with the tire pressure thing.
Mine are at about 34 and have no issues at 20 or 75.

 

it didnt make any difference. I'm convinced at this point it's the steering angle sensor. Wondering if the guy didnt to the reset on it. Or if it's just bad.
you guys do know you dont go by the tire pressure listed on the car right? As car get older tires go bad as we all know. And new tires get put on. You can't spec a world of manufacturers tire specs for the life of the car and print it on the car.
for instance. My old dodge truck had load range D tires from factory. But I put light truck tires on because I wasn't hauling or loading the truck down.
now load range do normally takes 65 to 80 psi of air. And that's what printed on the truck tag. No what would happen if I filled those tires per the spec on the tag? BOOOOM!!!!
always go by the manufacturers specs not the car. You never know what the guy before you did. Or if the brand of tire you buy has a odd spec. Better safe than sorry. You guys likely know this this. So I'm left wondering if there's something hhr ss specific I have no idea about. My old 944 turbo wanted 35 psi on the door tag. So I'll leave this as a question.

 

You're still running the factory equipped wheels, which means you are running tires similar to the ones that came on it. You should stay close to what the placard says, and at 35, you are. But like I said before, 37 would be too much.

 

Just an FYI.
I can set my tires at 32 psi cold, all 4. Hit the interstate on a 75-80 degree day, 50-100 miles later my tires have risen to 36 or 37 psi.

Just sayin..............

 

Yes, but if you start at 37 cold, you might be in for a wild ride.

 

But what’s printed on the placard? On an SS it’s 32 PSI cold.
