Whatever it says inside the drivers side door jam is what you should run at. If you're hauling, up the pressure maybe 5-6psi in the back for good measure.So, if the max pressure on my tires is 50psi what should I "nor4mally" be running them at? When I pull my trailer (26'/4700 lbs) what should I be running the tires at? Thanks
No one pressure is a good choice for everybody.So, if the max pressure on my tires is 50psi what should I "nor4mally" be running them at? When I pull my trailer (26'/4700 lbs) what should I be running the tires at? Thanks
Whoever did that report is full of it. Underinflated tires will scrub more than properly inflated tires. This scrubbing is extra friction that the engine has to overcome. The more the engine has to fight this, the more fuel you use and in turn the lower the mpg you get. Think of it as riding the brakes a little. It's the same effect. Or, imagine pushing the vehicle. Would you rather push it with 4 flat tires or with 4 inflated tires? The smaller the contact with the ground, the less friction you have and the easier it is to move. The easier it is to move, the better your overall mpg will be. :tu:Not to be contrary, but in recent weeks I saw a report that tire pressure had no effect on gas mileage. The report said for safety reasons you should not allow the pressure to get low. They had tested tires under different pressures. I'll see if I can find it and post it.
Well, here is my personal experience with tire pressures.If I keep my tires inflated to the max will my mpg increase? Will this cause my tires to wear faster? Will it decrease traction on wet roads?
