It will be on a sticker on the driver's side door jam. The Trax only weighs 3,069 lbs, 4,145 lbs. is the max allowable weight of the vehicle, occupants and/or cargo at one time.

 

4,145 lbs. is the max allowable weight

That's what's cited as the weight in several of those yootoob "influencer" reviews, making the Trax "on the heavy side," dontcha know.

I did find a site where the weights where the curb weights were listed between 2970 to 3124 depending on trim, negligible in the real world, of course. I lost the URL for that data. I'll bet that 154 lbs is optional splash gurards...

 

Motor Trend quoted 3,096 lbs so I picked that one. I HATE most of the easily-influenced SheepTube videos, but I do watch Jason Camissa, Motor Trend, KBB, Alex on Autos, Sarah n Tuned and occasionally TFLCar/Truck.

 

My Chevrolet App/vehicle status it will show you the recommended tire pressure, below

 

I also use the tire pressure recommended in the app.

 

Same here. My 1RS with 18 inch wheels had the tires at 40psi with one of the rears at 41 when I checked them with a gauge the morning after I brought it home. The sticker on the door post says 35 front and 32 rear so 9psi is far more than a bit over-inflated. But one would think the dealer would check tire pressures before letting a new car off the lot.

 

Almost every car I've purchased in the last several years has had the tires inflated way above the placard pressures. It seems that the prep boys and girls might read the max pressure on the sidewall? I always quickly check about five other maintenance issues (oil level, washer fluid, brake fluid, etc.) I don't trust any dealership staff anymore. Maybe that's too harsh, but better safe than sorry.

 

The placard pressures are more than anything else about ride quality without crucial endangerment due to inadequate tire pressure at GVWR. Under inflation is more insidious than over due to heat build up.

The load rating data in weight and pressure are on the sidewall of the tire. The tire would be over inflated if the pressure exceeds the sidewall value.

Page 174 of the owner's displays a label we don't get which would show the inflation pressures needed to obtain the gross weight capacity of the vehicle:

Inexplicably, we get this label on page 172 which tell us nothing about tire pressures other than a "cold" value:

(It should be noted that GM employs only the most expert and talented technical writers and illustrators for their owner's manuals.)

For my Trax LT, I get 948 lbs. As my Hankookies are rated at 51 PSI and 1709 LBS, they're well capable of the GVWR.

However, without what is a load inflation table, for my 948 LBS, if Uncle Joe Bob and my two cousins were passengers, I'd have to SWAG¹ an increase to about 45 PSI from my 35 "cold" PSI for an extended ride.

Theoretically, one could run the tires at the max sidewall pressure full time and increase fuel economy as a result of much lower rolling resistance (with horrible ride quality). In fact, that was suggested by our august gummint leadership during the oil embargo back in '73-74.

All that said, I wonder what kind of fuss the TPMS would put up with for any deviation from the "cold" tire pressure?

¹ Scientific Wild A** Guess

 

And if you did that, your tires would wear out in the center tread area considerably more quickly than you'd like.

 

if you did that

As you quoted my entire post and I don't live in the center of your universe, I'll best-guess "that" refers to "run the tires at the max sidewall pressure full time " and about Uncle Joe Bob and my two cousins. If not, I'm otherwise indifferent to your reply.

You suggest running at max PSI would bias distort to center tread, thereby reducing traction and sacrificing safety. It does not. Designed handling and safety characteristics exist in the cold-to-max PSI range at any load up to GVWR.

Granted, overinflation center tread wear could occur if you managed to find bias-ply tires to fit to your Trax wheels. Belts were envisioned long ago, made practical post-WWII and became mass production and economically feasible in the 60's.

For radial-ply belted tires, if the maximum PSI is exceeded, and to ridiculous. malicious or ignorant degrees, diminished sidewall physics would affect safe design geometry by forces being transferred to the shoulders, tread and bead filler. Heat would cause catastrophic failure long before uneven tread wear could be an issue. In a hypothetical model where heat might be dismissed, wear would be toward the beltless shoulders, the belts being the heaviest in the very center of the tread.

The same would hold true for bias-ply belted tires, but the cold-to-max PSI delta would be considerable less in range.

FYI to the community: I used the word "theoretically" in #10 in the sense that no one would actually want to run max PSI at normal load, not only for the decrease of ride quality, but the increase in operational temperatures will decrease the life of the tires. During the '73-74 oil embargo, popular and editorial outrage was directed at the D.C. elitists for their pathetic attempt to absolve them for their failed foreign policies by directing the populace to engage in the practice.

Cheers.

Yup; I was referring to running at significantly over the recommended pressure. Doesn't really matter what I say; do whatever you think is right and, over time, you'll find the consequences. If I'm wrong, so are a whole bunch of other tire engineers.

 

I always run my tires about 4 psi above what they recommend. Sure, it may ride a little rougher, but gas mileage goes up a little also. Drivers need to find that "happy" median.......between mileage and ride........
BUT! I also know most People are not that...."involved" into their vehicles. They just want to get from point "A" to "B". I understand all that myself!

I remember working at Wallyworld, in the tire and lube department. I will SWEAR!! A Woman came in, and had about 70 psi in every tire!! I was amazed, that none blew up into Her face! So.......they can hold more air than one thinks.

OH YES!! I DID also sell Her a tire pressure gauge!!! LOL!!!

 

Car doesn't weigh 4145, it weighs 3086 lb.

 

I think the high tire pressure has something to do with shipping the car.
Dealer is supposed to put the correct amount of air in before they sell it.

My dealer didn't do mine, they were all over 43psi.


!

 

35 PSI in the front
32 PSI in the rear

 

I'm going to jump in this tire pressure discussion. Late, I know. Due to the months spent on a ship tied down, the tires are inflated to 48 psi so they don't flat spot.
High tire press. Keeps the tires cooler, with less rolling resistance and less wear.
The door sticker PSI represents best road feel, bump isolation, and comfort.
Running higher up to the cold tire press. listed on the tire is safe, better for the tire, mileage and power.
I run my Chevy Cruze at 45 psi. A more "sporty" ride, tighter handling and more power and fuel economy.

Got a Trax coming by July 1st. I'll experiment with slowly increasing the tire press. on it to find it's place. Won't be at 32 psi.

Flate rate is why tire press. is not checked during the PDI at the dealer. A PDI is a big $$ maker for techs. Pays 1.2 hours, can burn through them in 15 min.

 

My 2024 Chevy Trax activ came with 48psi of pressure in all four tires. Should have been checked at the dealership during pre-delivery inspection, but it wasn't. I put the air pressure to factory recommendations 36PSI front, 32PSI rear.

In my opinion the car rides way smoother at the factory recommendations. 48PSI makes for a rough ride.

There has also been reports of tire blowouts. My opinion, this is due to high tire pressure.

I personally feel if higher tire pressure gives you better gas mileage, it still isn't worth the trade off for the ride!
