3.3TT 2019 Stinger GT1 Tire Pressure Way Off

[KGT1]

Same issue for me and my Stinger. Drove on 50psi tires for 4 days... can an admin create a sticky or PSA? There may be tons still driving on max psi and since the tpms does not alert for high psi they still may be driving on them...

Crap, mine are at 50 from the dealer too.

 

[KGT1]

Wow.... I guess this really is a widespread issue then...

 

[Leonidass]

Speechless..

This one definitely is widespread; and most drivers don't know it is going on. I agree with the sticky suggestion; this should be on the front page to alert the unwary.

Just a matter of time before someone who just a new GT hits a pothole at a high speed and bursts their rear tires into a spin out.

Call Larry H Parker. He’ll fight for you!

The c. 50 psi isn't going to burst a tire because it isn't above max manufacturer specs. And a pothole that can burst a tire will burst any tire at any psi.

The risk is much higher with the pressures so high. And 50psi cold is 55psi hot...

Agreed. I've read some older research that the number is 200 to 250 psi to burst a tire. I even saw an outlier that was much higher. I think that pressure ratings have less to do with tires bursting and more to do with treadwear location and vehicular handling. An overinflated tire is likely more dangerous from a handling perspective than a blowout perspective, but that is just a hunch.

That hunch is correct. And long before the handling gets into dangerous (normal driving) territory, practically any passenger is going to be asking what's wrong with this ride? The noise and harshness would be present long before any danger of losing control or damaging a tire on a pothole.

Even damaging a tire is secondary to damaging a rim. And in this case the harder the better!? But who wants to overinflate their tires to the point of saving their rims if the ride sucks?

Surely posted above, but high pressures are for transport across the water, and are supposed to be reduced to placard stated pressured during pre-delivery inspection.

My 2019 GT1 AWD (staggered, 19") came at 38 cold, ~41 hot. I need to double check the door jamb (I'm guessing it says 36?), and probably drop 'em 2 psi or something, but it's close enough that I'm not upset about it, or feel like it's an immediate problem.

 

[Stinger305]

I'm surprised no one stated the correct psi in the whole thread, but it's 36 front tires and 39 rear.

I just had my oil change done at the dealer and was sitting at 38/41. Got the car back at 40/41, so it seems like they just inflate to 40 and call it a day. When I first drove it off the lot thought it was 48. Same problem.

Is that for all wheel combos?

Nope.

19” RWD / awd staggered (are each different) as is 18” square which is what he replied to)

 

[KGT1]

My AWD GT1 with 19s state 38-front 36-rear.

 

[Stinger305]

Thanks for the chart! I should've realized there were different tire combos.
