Tacoma offroad model tire pressure

I took delivery of my 2023 Tacoma Off road a few months ago.

Went camping and pretty much loaded it up. Canoes, gear etc.

It has the standard 265 70 R16 tires.

Sticker recommends 32 lbs air pressure

Tires looked pretty much pushed down and I put 40 pounds air in front and back tires.

Back home, unloaded all the gear.

Been a few days and I think the truck drives much better at 40 lbs than 32.

Question for you more experienced Taco owners is: Am I going to hurt anything if I keep the 40 lbs air pressure which is higher than Toyota recommends?

 

^What's max pressure written on the tire sidewall? I seem to remember it's 37 psi, which would mean 40 psi is too high.

 

I also have a '23. Same size stock tire - mine are the Wrangler Territories. Door panel says inflate to 30psi all around and the tires show a max inflation pressure of 51 psi. I run mine at 30-32 depending on ourdoor temp. 6000 miles on them and they are wearing evenly.

 

You'll just burn the center tread for no reason. Loaded 40psi is fine, but drop it back down to 35psi or less for better wear.

Tires are supposed to squat. Appearances dont matter.

 

this!
Overinflated will just oversize the center of the tire,, which to you is probably why it feels better, it has less rolling resistance and less side flex,,, but since it's contact patch is significantly smaller,,, so is the level of traction it can provide.

 

Wear and heat will be an issue and you'll also start running into vibration issues as well. Toyota will generally fill them to 35 PSI in the summer which has them well above that on the roadway. My door sticker says 30 psi when cold. Once I removed the excess air and set them back to what the door sticker says, my vibrations were greatly reduced.

 

Braking performance will suffer when overinflated too. Door pressure is probably where you want to be.

 

What model do you have that 32 psi is on the door sticker? Long bed or something? I thought all the Off-Roads are 30 psi.

For the stock tires, you definitely should stick to the sticker pressure. 40 psi is never appropriate on passenger rated tires, to need 40 or more would be LT territory.

When you change to a different size or load rating, then use a calculator based off of the stock load/size/pressure to calculate what the new tire should be aired to. Appearances of the sidewall don't matter, that is not a metric for properly inflated.

 

My long bed I am certain says 29 psi

 

30 psi is the recommended u can run between 32-33 cold . 40 is way to much and will wear out your tires quicker and unevenly. Possible blow out could happen being over inflated . If u are running at 40 cold then when they are warm u will be at 45 -47 depending on speed .

 

If your tires are rated for 40 or more 40 won't cause a blowout. Low pressure causes more great which can lead to a blowout. High pressure can cause wear issues and possibly less traction.

Tire pressure depend on many factors, tire construction and load are important. High chance that at least loads are varying across trucks.

 

Chalk test

 

thanks for the feedback

I think I will go with 35 psi cold

 

May even depend on season. AZ summer a "cold 35" can expand to 40 quickly, but in winter may only expand to 37. I just reinflated to 33 cold because it had dropped to 30 cold (through time and some use in light-offroad space that was not supposed to be serious offroad) and my MPGs dropped 1-2. Now at 33 cold it expands to 36-37 in use and MPGs back up.

Center strip on my tires looking perhaps lower than sides, probably should ask Discount Tire to measure the side-vs-center tread to diagnose the condition of the tires.

 

"Toyota" has nothing to do with it. It's the place you take it to and it sounds like you're using a dealer. The inflation is usually based on the person using the hose and nothing scientific. Most of those guys don't bother looking at your door jamb sticker neither. Most put too much air in tires and torque wheels way too tight.

 

Actually Toyota technically does given that I've heard from several users on here (including those who have worked at dealerships) that it is standard practice at the Toyota dealerships to fill to 35 PSI in the summer. I'm aware they don't look at the door sticker or I wouldn't have to let air out of my tires after they've finished performing the service each and every time.

On the flip side, I drive so much that I'm getting service done about every 2 months and so I can't forget to check my tire pressures.

 

Tire pressure is a function of load. It could be considered as an air spring. The pressure recommended is to ensure load capacity and tire longevity. Over inflation can be just as bad as under inflation causing premature tire failure.

My Sport recommends 29 psi...


If you change tire size or load rating, it is important to set the pressure to match the tire...
Here is a calculator make sure you have the correct pressure

 

Sticker on the inside of the door says 30psi. I thought I knew better than that shortly after picking up my '23 TRDOR and inflated them to 35psi. Found out it rides better (less jarring on bumps) with 30psi. So, 30psi it is.

 

These threads always crack me up. You can safely run a pressure that is at least what the placard shows up to the max pressure on the tire. Of course these are always cold pressures. Anything in between is up to you, your driving style and your comfort.

And as always the chalk test is pointless and a total waste of time. I have no idea why people still suggest that nonsense. There is zero scientific data that is provided from that.

 

You'll have a little bit of convex nature to your tire profile which would create some uneven wear maybe? Whatever feels comfortable within the recommended tire limits should work well.
