Tire Pressure

Hello,

I have a set of Goodyear tires, and they may max pressure is 65 ft/lbs of pressure. I am not sure what Ford suggests for tire pressure, so I tried 50 ft/lbs. It is really bouncy. Should I try the max pressure.

Are there any temperatures I should be cautious of?

Thanks.

The max pressure is just that, the max. It is not the recommended pressure for routine driving. If you have it at 50 psi now and its bouncy, more psi will make it worse. I don't remember the exact psi right now but I believe its around 35 psi (this is all asumming you have stock size tires and rims) My truck has the recomended tire size/psi on the inside of the gas door, its also in the owners manual and I think its on the info tag on the door. Take care of this issue or you could have an blow out or at the very least your tires will not wear properly. Good luck.

The max psi on the tire is for safety. Tires will increase in preasure due to expansion of the air when the tire gets hot, it's usually about 3-5 psi.I don't run my tires at max even when I tow, but I do increase the tire when I tow. If you increase your psi above comfort ride, but not max, it will help on gas milage, due to less drag.Like triton said if there not stock tires, go by what's on the tire.Example my tires max out at 65psi, but I run them at 46psi. Keep in mind if the tire is under inflated, it will wear on the outside of the tire and heat up more and yes possible blow-out, over inflated will wear the middle of tire. Hope this helps. Rich

Karen,

Do you also get that bouncy ride I'm talking about. 46 lbs is lower than what I put
and frankly I find it a bit too bouncy.

I was seriously looking at installing 33 in tires and I changed my mind because I was told it would be even worse. I was told to go with low profile tires on big rims to solve this.

Thanks.
Peter

I take it you have a 4x4 according to your sig. I would'nt go to low profile on a 4x4. What is yor size of tire? I have 33" tires and I have no problem of bouncing, just if I inflate to 50psi cold it rides hard. The bigger the tire the bouncier it will be, like a balloon.

Maybe it's not your tires, maybe shocks. Upgrade your shocks to an off road shock, Rancho makes good ones. Do you have the stock shocks? I changed mine cause they were to spongy.
