Tires

MikeHTally · Jul 15, 2022

Airless tires ("tweels") have been around a long time. Michelin put some on a Corvette a long time ago. They worked great, handled well, were nail-resistant, etc., etc. One thing they can't handle: mud. It gets caught in the webbing and throws the balance WAY off. Great idea for lawn mowers, not so much for cars.

Thanks man I’m no longer riding like basketball jones !!! I mean I was bouncing down the road and my wife has pins and rodd on her spine in her back !!! She said this can’t be rite now I use the psi indicator on the cluster at all times and my wife’s back feels a lot better !!
She rides smooth and clean !!!
From what I’ve read most of us got our trucks delivered from the dealership at that high of tire pressure 48 psi. Why will never know !!

I wasn't aware of the reason for the delivered PSI and I did ask my Dealership not to touch the car but mine too came dramatically overinflated. Now I know why.

Because as was posted earlier, they over-inflate the tires during shipping/storage to help prevent flat spots. It should have been taken care of with the "148 point pre-delivery inspection" LOL

GearHead_1 · Jul 15, 2022

Yes, I picked that up in this thread but didn't know it before hand.

I've seen many posts in the past where the vehicle was delivered with the tires over inflated. Pre delivery check should have corrected but many did not. Mine included. Glad to hear your enjoying the ride once you lowered the PSI.

Big Turk eluded to it as well, you would just wear down the tires uneven and much faster than designed. You'd be surprised how quickly you can mess up tires with bad alignment/improper inflation, etc. Unless you're going to be towing or loading up the ST with stuff for an extended period of time you don't really need to adjust anything. Towing changes a lot of things so always suggest doing research for best practices depending on what you're hauling.

No mnf will cover tires against wear when you don't take care of them. Simply checking your tire pressure every now and then (quick button click on steering wheel) and making sure alignment is checked at least once a year (depending on how much driving you do). I have lifetime alignment on all vehicles so go twice a year unless I have suspension work done.

your late to the party and what if the tires are not stock? what if someone bought the St and tires were different but they didnt know. this is the only car in my life that I am not changing the wheels and tires. so yea the door isnt where I am looking.

look I know its not important but the reply "much faster" isn't a answer. that's very relevant much faster to you could mean way different to me. Id be willing to bet any amount of money you want there is no real difference between 33 and 36. Real meaning if tire life is 50K miles they wont be gone at 40K.
your also brining in alignment that's a whole different subject

Assuming the replacement tires meet the OE specifications the door jamb is still the right info. If you start moving into the plus sizes beyond zero that becomes a different matter.

I agree 100%

Rite now my preference is 36 psi my wife’s back is not in pain and she’s handling well and not bouncing like a basketball !!
What confused me 48 psi at delivery I drove it like that also, very happy to get everyone input on this issue.

Still the same pressure. Take a picture of your tire sidewall and tell us what it says about the various vehicles the tire will fit. Look closely, we'll wait.

DaveG ST · Jul 18, 2022

Some dealers just keep them overinflated so that those who are unaware that the pressure will go down in the winter don't come running in saying there is something wrong with their vehicle when the tpms warning comes on. We know to add a little air, but many do not. Plus, they need the time to make other repairs, such as the cat converters, throttle bodies, seat trim, window switches, axle sensors, and the such.

I looked at my tires with a magnifying glass and the psi pressure is not listed anywhere on the tire. Rite now I feel comfortable at keeping my psi pressure at 36 rides like a dream now.

I had looked at the website and it said 50lbs max. 36 is fine no matter what anyone says!
