Tire pressure (psi) for best tire durability and MPG.

Hi All,
I have the stock Hankook tires (P245/75R16) on my 2016 Tacoma.
What pressure should I run on them for best tire durability and mpg?
The driver's door says 32psi, and I have 33psi on them now.
Thanks!

 

I'm running 35psi in my Hankook's.

 

The pressure on the door is the recommended rating for any tire on the vehicle as it is derived from the vehicle weight. Has nothing to do with the tires themselves. NOTE: this is for the recommended tire size for the vehicle. If over-inflated you will wear out the center, under-inflation and you wear out the outer edges.

 

Sorry, to recap...

Do we run the manufacturer of the tires recommended air pressure for the load or run the Toyota truck side door pressure?

Are the pressures effected if you go up a tire size?

 

Run the door pressure. Typically the pressure is not affected when going up in tire size. 32psi is 32psi! are the load properties the same on both? Rating? I dont recall the load rating on the stock tires.

 

For example. I have cooper ST Maxx. They say to run 50 PSI, if I don't they won't acknowledge warranty on the tire (on top of having to rotate). Toyota side panel says to run lower pressures. What to do...

 

Who says to run 50 PSI?
The PSI on the side of the tire is the max pressure, run the pressure listed in the door.

 

Mine tend to get dry rot long before I burn half the tread.

I tend to run around the recommended door pressure unless towing and tires looking sad.

 

Won't have my truck for at least a month (if I'm lucky), but this is my number one pick for tires. Would love to see a picture. Planning on stopping on the way home so the wife doesn't see my stock tires. She doesn't get it.

My two son's understand....

 

What is the rating of the tire? Instead of listening to Bubba Gump at the tire shop, call or email Cooper Tires. I deal with this crap all the time...my daughter goes and gets tires rotated and then comes to my house to check them. They are the rated tire for the vehicle and the door shows 32. I check and the tire place puts in the max on the sidewall (45). So if you vehicle weighed another 2000lbs then 50psi might be correct. I had coopers on my Jeep and ran them at the door listing unless I aired down for wheelin. If Cooper says run 50 no matter what then I would run 50.

 

Also running over-inflated tires causes other issues... Handling, noise. I felt something odd the day after I picked up my truck and the tires were over-inflated for the transport. Aired down to 32 and no more issues.

 

For better tire durability and MPG as your focus, run closer to max cold inflation listed on the tire. You can improve your MPG by big %. There will be compromises such as a rougher ride, possibly less grip on wet roads which you should test out, however you may see better resistance to hydroplaning with higher psi.

I feel a lot of tire wear occurs when turning, which is where extra pressure helps them last.
I find on my vehicles I get LESS tire wear when I have pressure considerably higher than door sticker and you can notice the vehicle rolls easier. It can even be safer because tires run cooler especially loaded.

If you run snow tires, I'd only run them at 32psi max since snows seem to wear more in the center and tires are expensive.

 

Max pressure for the cooper st maxx's is 80 PSI. Shop said run 50psi as that is what cooper recommends. Toyota door says 32 psi or whatever (but does that assume stock tire and tire size). I will try the door pressure.

 

I don't think you'll like 32 psi with those.

 

Talk about confusion ahaha!

 

I run 34 35

 

80 psi means you have load range E, enough for 1 tons. I think you'll be happy in the 38-50psi range.

 

Proper tire pressure will vary by the tire size and characteristics. Toyota recommended pressures vary by 3psi depending upon which tires your vehicle came with. If you alter size beyond the OEM options, proper pressure could vary even more. As noted, you need to see how a given pressure/tire combination works on your vehicle and that just requires some testing.

 

since the weather cooled my tire pressure at start up is 26 once i roll down the road a couple of miles it goes back up to 30! thats on a trd off road dc sb stock tiers. do i need to add more air to them for (winter) although one day is 40 degrees the next is 80 here in Louisiana!

 

I increased the pressure on my stock Goodyear's to 34 PSI all around. It helped MPG and it also feels better going down the road. 29 PSI was just too spongy for me.
