I went to have my 1st oil change on my 2004 Z-71, 1500 Crew Cab yesterday at the local Jiffy lube. As part of their service they check your tire pressure. They told me that ALL my 17" tires were at 45 to 50 PSI and that they are not to excede 35 PSI. If any of you have just purchased a new 04 Silverado you might want to check your pressure on yours.
I would be interested if anyone else has their pressure too high. I checked the tires and the badge on the drivers door and sure enough the pressure rating says 35 PSI (When there cold) If this problem is on alot of their vehicles, then the factory needs to be aware.

Thanks for thei onfo. I've had my 2004 Silverado truck for a month, decided to check the tire pressure at lunch after reading your thread. My tires had 45psi on all four, with the same recommended pressure of 35psi on the door. Seems like the dealers need to know to avoid a big safety issue. Again, thanks for sharing the info and getting me to a safe tire pressure. Marty

Keep in mind that if you checked the pressure while they were COLD and they were 45PSI then that pressure is going to go up as the tires heat up.

On my tires it says not to exceed 40PSI.

You need to use what the tire says instead of the sticker inside the door. That sticker is only for the tires the manufacturer puts on the vehicle at assembly. But as y'all have said, I run 35psi in every tire I buy that is under 36" tall.

My tires are factory tires so therefore the sticker should match them. The tires say maximum of 40 psi and minimum of 35psi. I'll keep them around 37 or 38, not 45 to 50 like they came with.

Just some advice, I've worked at a tire shop for about 7 years. Unless you haul alot of weight, I would use the lowest recommended pressure. It will ride better, and probably wear better (especially the rear tires). The more weight you haul, the more pressure you add to compensate for the load.

you guys got me worried i'll have to check mine after work. i'll let you know.

i checked an my tires say the max is 44 PSI and they are @31 PSI at 58 degrees so mine is ok, but I got my truck in Jan. and in NewEngland here it was 20 below for a while. But i think mine is ok.

My door sticker says 35psi also but I have the factory option tires and they go up to 50psi. If you run 50psi on a truck that spends most of it's time not carrying a load or pulling a trailer then you will wear the center of the tires out. I keep mine at 45 and all is well.
