Mine were also at 49-50 psi which is way to high. The door sticker says 36 psi, so I set mine cold at 38 psi. The ride is better now, not as harsh. The max pressure for these tires is 50 psi which increases the risk for a blow out especially when the tires warm up and add another 2-5 psi after driving.

Before finalizing the paperwork, took it for a test drive. Tire pressures 48 - 49. Told sales dork to get them adjusted down to 36 while finalizing papers. Dim wit sales guy never did.
Door jamb sticker (driver’s door jamb) says they are to be 35PSI, cold. Cold is defined as not driven for 12 hours and no sunshine.

Maybe all the Trailblazers shipped from Korea had tires set at 48psi? I was actually shocked they had that much pressure in them considering that's near the max for these tires and could pose a safety risk. :rolleyes:

Just picked mine up today! Viewed the tire pressure from the app while it was being detailed and had them fix it! Tires were between 45-47. Way too much. So glad I saw this post.

I just googled this, found one thing out there that says they over inflate so they don't get flat spots during shipping.
