2025 tire pressure 41 PSI ???

[moose4now]

I just purchased a 2025 LT with Firestone tires and according to the sticker in the door jam, the tire pressure is supposed to be set at 41psi. I understand there are different PSI requirements to meet loads with certain tires, but what GM engineer would pick a tire that has 41 COLD PSI on a passenger vehicle. When set to 41 COLD PSI with firestone tires the vehicle rides like a tank. It's a terrible ride.

Yeah, can't wait until the tires get some miles on them and what the ride will be like....LOL

When I bought my 2002 avalanche it had firestones on it. They were hard and lacked traction, so I decided to replace them at 7,000 miles.
As far as the 41 pounds, I would probably go with 36lbs to soften the ride. If they start wearing on the outside edges pump them up higher.

Already discussed in this thread: https://www.chevyequinoxforum.com/threads/2025-psi-41.4893/

The detailed answer, by me. : https://www.chevyequinoxforum.com/threads/2025-psi-41.4893/#post-23949 - It's because of the tire size, 17" versus 19". The smaller tires need more air to support the weight. If you do decide to lower the pressure from the sticker numbers please be cognizant of this part of that post:

For whatever it's worth, my 2020 Equinox Premier with 19" wheels has 35 PSI for the sticker. Because we live in the snowy north and the tire pressures will drop about 5 PSI from summer to winter. I pump mine up to 40 PSI about September or October and they drop to 35-36 in the coldest months. I notice exactly zero change in the ride or handling.

I thought in the previous years (2018 to 2024) the Equinoxs with the 17", 18" and 19" wheels all had a recommended pressure of 35 psi.
Recommended tire pressures have risen over the years. (Tire pressure is a compromise between handling, gas mileage, tire wear and comfort.) My wife's 2008 Malibu has a recommended pressure of 30 psi.
Seems like my 2008 Equinox Sport recommended 30 and 32.

I always use a tread depth gauge on all my vehicles and always get consistent wear when I use pressures that are higher than specified.
It's anywhere from 2-5lbs more and it depends on vehicle and placement.

So, if the mfg recommended 41 psi, you might run them at 46 or so ? Wow, sounds a bit scary to me.

If you notice your tires wearing on the edges, more pressure will lesson that. If they're wearing in the center, it's a sign the pressure is too high.

Tire pressure specifications by the manufacturer compromise somewhat when it comes to ride quality.
I never approach maximum pressure and I do check after a drive to double check.
Your mileage may differ, but the tread depth gauge doesn't lie when it comes to if the tire pressure is right for your vehicle with the mounted tires and the position they are mounted in.
Get a digital pressure gauge, I only use the TPMs for a quick reference.

As a former tire shop employee, I learned that heat is the biggest enemy of a tire. The less air your tires have, the more they heat up. Conversely, the more air, the cooler they run. Keep this in mind when deciding to lower air pressure, especially if you live in hot climates.

FYI, we all ran 3-5 psi over recommendations in our own cars - I followed the same with all my cars since with excellent results. Never had the center treads wear faster.

Since then, nitrogen has come along and seems to offer the added benefit of not heating as much as oxygen. Whatever you can do to help your tires stay cool is a good thing in my book.
