whats your ideal tire pressure??

[baddohtentahoe]

dealer set all mine to 32 psi before my alignment. they look too low tho. i usually keep them so they are right around 40 psi when they are hot. so 36 psi cold. is this bad you think..?? its just in my head that my gas mileage goes up when they are higher. i dont tow tho.

Depending on what tire you run, you may have the correct air pressure. iI had the same question before and was informed that 32 psi COLD on my tires (see my signature) is the way to go if you want the tire to last. You will have to check this all the time and stay on top of it.

High air presseure equals higher MPG's, so this is NOT just in your head. It depends if you want better gas mileage or your tire to last longer, your choice.

I stick with the 32 psi COLD, as buying a new set of tires quicker hurts me more then an additional 5 bucks at the pump.

Im running about psi 40 for my winter 17s and 35psi for summer tires. I like to add a little extra air for the winter because every 10 degrees in temp drop, tires loose about 1psi of air

overall ideal, what the truck was engineered to have, is on your placard on the drivers door. it recommends size and pressure

So if im running 33's(cepek mud countrys) and its getting warmer where i live what tire pressure should i run that is ideal.

 

[Rivieraracing]

I run 35 psi all year round on my denali!

like what JochenWoern said higher pressure is better for mileage but it all depends on what tire size and style you go with. over inflation wears the center of the tire and under inflation wears the outsideds of the tire. So if you have the stock size it is ideal that you go with what your drivers door says. on my impala i used to keep it at the high end even a little higher and i got better gas mileage but my tires wore a lot faster and the tires on my tahoe are a lot more expensive so it wouldn't make any sense for me to run them high because i would end up replacing them faster

35 here also.

 

[Campi3ell]

32 "looked" too low for me also, even though the truck rode fine. With temps changing so often here in ATL I have learned to up the psi to 35 to compensate for any loss. ride is a bit better (on-ramps, curvy roads, etc) and gas mileage has upped slightly

I've been running 36psi cold on my 285's. It seems to ride better and handle a little better. But I still think its to low, tires just look a little flat. And if I run 32 or 36 my fuel mileage is still ******, but I don't drive it for fuel mileage. I drive it for comfort and function.

Interestly enough, Michigan State Police recommends Tahoe pressure to be set at 44PSI.
I will say that running higher pressures will aid in better fuel economy because of less rolling resistance but also less contact patch. Some hypermilers (ie treehuggers) recommend as much as 90 psi.

Science agrees, safety board probably not so much...

So what pressure do you run Jeff? 44 or 90?????

 

[TSFR]

44psi.... They went through all the trouble of printing a little sticker and everything. I didnt want to chance fate

 

[afpj]

tsfr,

i have michelin ltx's on mine and 44 psi is max i think, but i go with 35 psi which is stock recommendation on the plackard. what tires you running? i saw your link and looked at your ride...very clean. i like the rear bumper guard, not seen those often. i have to ask, where's the laptop? your front passenger space looks too clean lol.

LOL Man dont make me lie, thats how I got. SUPER clean truck! I couldnt be happier with the choice. I am a minor techy but no laptop tray. I am however building a secure drawer in the back with a sliding shelf on top. Just deep enough to store my gun case out of sight while we are out going to and from the range. In case we stop for dinner or something, I didnt want it to be as easy as breaking the glass and running away with it.

I would suggest to run what the tire says, not whats on the door. Chevy put the tire pressure there to offer the "best" ride, not having anything to do with what the tire manufacture recommends. My tires say 44 psi max so I put 40 psi in there to allow the tires to warm up to ~44psi.

What if someone puts a heavy duty tire on their truck...say something that recommends 80 psi, I definitely wouldn't run 35psi in it

Sorry, but I disagree with you here. Maximum pressure is what the tire is rated for under loaded/MAXIMUM conditions. It does not mean that the air pressure in the tire should be at MAXIMUM for maximum performance. The max. pressure on the sidewall is certainly not a "recommended" pressure.

The tire manufacturer also does not know under what conditions the tire runs. What I am trying to say is, the tire could be installed on any vehicle (within reason of course) and could therefore have a lighter vehcile weight or a heavier vehicle weight on it. The max. pressure on the tire sidewall is based on what the tire can handle, not on what the best pressure for best performance of the tire is.

If you are running your tire under normal, not loaded conditions at the max. pressure, I can almost guarantee you that you are not getting maximum wear out of your tires.

Agree^^

Most tire manufacturerers give you a max high pressure. I would always try to see what works out for you. Example my 22 inch tires say max air pressure 55 psi cold at full load, 3500 lbs. If i used my yuk everyday to tow a trailer i would run them at about 50 psi, to allow for some expansion. I got them for everyday use at 35 psi, and it works for me. Ive run them at 30, 40, 45, but found that 35 for everyday gives me the best ride. If i am going to tow i adjust the psi, depending on how heavy the trailer is.

 

[Ninety5PoloZ]

Just what I have been told, and I will continue to do as I always have. My tires are currently set at 40psi cold on all of my vehicles. My Taurus I got rid of suggested 32psi and thats what the tire installer put in the tires. I will say that the ride was scary and "loose" I put them up to 40psi and they were great.

35 here also.

GO WILD!! lol
