What should tire pressure be set to on Take offs?

[Red Rider]

So I just installed GM 2015 tires and with 18" wheels i picked up off CL this afternoon. They guy had a 2015 Tahoe. They look Super nice... My truck is a 2004 tahoe Z71.

I checked the pressure and the 2015 tires all had about 35-36psi in them. The 2004 is supposed to run on 30psi. I assumed I needed to take them down to 30, but front tires look kind of low.

Anyone have any ideas of proper tire pressure for this situation?

I guess I should look at the weight of the new vs older tahoes as well.

thanks.

35psi won't hurt anything.

I checked on Cars.com

GVWR Loaded max weight
2004 is 6,800 lbs
2015 is 7,300 lbs

Curb weight
2004 is 5,262 lbs
2015 is 5,545 lbs

GAWR Axle weight
2004 front 3,600, Rear is 3,750
2015 front 3,600, Rear is 4,100

Not much of a difference.

I pumped them up to 35. They seem nice an solid. Thanks.

The rating sticker inside the door is based on stock tire requirements if you have changed anything you can toss those recommendations (and thats all they are) right out the window...... I run larger than stock bfg rugged terrains aired to about 40 psi and get excellent tire life and i also carry loads and tow trailers. pay more attention to what the tires recommended max pressure to a given weight requirements are and adjust from there

the correct tire pressure is always in drivers side door jam
