High tyre pressures from dealer - check your pressures!

[Ozstung]

Took a 800+ mile road trip. Ride much improved with very slight increase in road noise. Tire wear doesn’t seem to be impacted yet. Tire pressure only reached 33 PSI so that tells me tire temperature not adversely affected. I’m leaving cold pressure set to 30 PSI for now.

Sorry if this is a bit abrupt but those tyre pressures are way too low. Had a stinger for 70 months now, for RWD you'll need 36f & 38r as recommended . A lot run a couple of lbs more.

Agreed. Check the driver's side door for the stock recommended pressures. That's what you should be running.

that's borderline TPMS warning pressures.

when I change wheels / tires for the season I have the psi set to 40 cold. over the next months this drops, for instance last spring I did this, and currently when I start up and the tpms comes on it will show 33 psi or a lb. or 2 more, and warm up to about 36 psi. next spring when I put these michelins back on I will have them raised to 40 psi cold again. in the middle of winter the 40 psi cold hovers right around there when warmed up. in summer, the 40 psi cold warms up to mid-40s psi, and on a real scorcher might hit 48 psi. yes, this is ten lbs. higher than recommended on the door card. but I like to corner fast and tend to wear out my outer edges first in front. so the higher psi offsets that tendency.

If you have a donut, don't forget to top it off too... 60 psi.

Or keep a tire inflator in your car. It's saved my ass a few times in the past few decades.

 

[rtv900]

mine came from the dealer at almost 60 psi also
no clue who thinks car tires get inflated to that level like it was a heavy duty pickup or something

The mail i got is Kia inflate them from the factory like that for the trip by ship then to holding yard and then the dealer. The dealer in his pre sales inspection is meant to lower the pressures to the recommended level.

Quite pathetic they skip this as you're paying for a deliver cost.

36f/38r is recommended on the placard off 10/17 Gt (Gt2) Stinger.

I have GT2 AWD and my door panel says 38F 36R, unless I'm reading it backwards. How odd?

Not odd for staggered, that is standard. Comparatively, 18" wheels squared on the 2.0L AWD are supposed to be 36 psi front 39 psi rear. our GT1 AWD also requires 38 front 36 rear.

Thanks for clearing that up for me.

Higher rear than front is pretty surprising. I could see the 4cyl reducing the higher front pressure (from the 6cyl) to match the rear due to a little less weight up front, but going from 2psi higher up front to 3psi lower seems like it would give the car much more tendency toward oversteer.

But maybe the reduced power or other suspension differences make this moot. Kind of surprised they didn't engineer it to be same front & rear pressure since so many people will do that, on the rare occasion they do check pressure.

The psi range for all trims of Stingers throughout production is 36-39 psi. We are not talking about a significant difference. I like to play with my psi, and TPMS system, knowing that on my cars the indicated TPMS psi is 4-5 lbs. lower than actual. This I determined by triangulating with two handheld tire gauges, that are within 1 psi of each other. What I do is keep the cold psi by tire gauge as close to the door card recommendations as possible, when I adjust my tire pressures. When I drive I expect to see the cold psi on the TPMS showing c. 4 psi lower than what I saw on the handheld gauge.

I'm staggered and set all to 34lbs cold this time of year, however the rear larger tires heat up a additional 2+ pounds over the fronts

I would be very curious what the differences in temperatures actually are.

I never saw any differences in temperature front versus rear when I was running staggered fitment.

Currently I am running square setup, and the temperatures stay within 1°C of each other (when at the same pressure cold) after driving at least 10 minutes.

You can check that with a $10 OBD2 reader and a free app.

Mine came delivered with 50psi all round as did my wifes Cerato GT back in 2019.... Noting would suprise me anymore!

You have the AWD in comparison to my RWD.

I got 40 psi all round when I picked the new Stinger up. Two in fact. Happy with that.

I since adjusted to the spec of 36 front and 38 rear and keep it there.

it's 38 front 36 rear
you have it reversed

Not for RWD, it's reversed from AWD. There are no AWD Stingers In Aus.
