Is this too much air???

Brought my truck to Les Schwab tire for the free air pressure check. Left with these numbers. Is it too much? Also seems like my mpg gotten better.

 

Probably rides like wooden wagon wheels too eh.
An overinflated tire can wear too. Really only way to tell is chalk test, since different sizes, tread style, build, etc etc can dictate that.

 

Bruh

 

Yes. Reduced footprint (traction safety), increased wear of center of tire, harsher ride.

Maybe. Over inflation is certainly a basic tenant of hypermilers

 

Yup, anything over 35psi is rough and causes tire wear issues on the factory tires.

I usually set them to 34psi warm, so when the temps drop its still good.

40psi is just a teenager reading the tire and setting it to max, or near max.

 

I run at 35 psi....and allow the tires to drop to about 33 before I add air. And I can tell a difference in ride quality. I would not recommend anything over 35 psi (warm).

 

So my door jamb sticker says 29psi but I swapped out the original wheels which were the 265/65R17. I’m running 265/70R16 Good year Wrangler DuraTrac on TRD PRO wheels. What should is set those at warm?

 

Well of course you're getting better milage. You're riding on the very tippy-toe center of the tread.

Not that the better milage is saving you money, after you factor the shortened life of your tires.

I'd deflate those to a reasonable number. Like back to the 30-32 neighborhood.

 

Are they standard load or LT E rated? You may need to show us a picture.

Most tire shops have to set E rated tires at 40psi now.

 

They are the Standard Load

 

All of these answers and not one person thought to ask about your weight/load!

If you're running a heavy load, you should add more air pressure (read the tire sidewall where it states psi under load.)

 

I run around 38-40 PSI. The 29-30 PSI is fine if you're not loaded. Most P rated tires call for around 44 PSI at max load. Since I haul a little weight quite often I like to split the difference. Otherwise I'd be airing up or down every time I needed to haul anything. I still get 45,000-50,000 miles out of a set of tires and the ride is fine.

 

Standard load tires doesn't change load capacity with pressure like an LT tire, spec is what matters 29-30psi cold.

Tire PSI stamps are usually max. That's it.

 

Tire shop was probably trying to see if TPMS will display a 3-digit number.

 

It's not Friday

 

Lol 32 psi takes this truck to like 8K GVW.
I run mine at 32 cold, which means 34-35 warm.

 

You still have the same diameter tire since you went down to a 16". I went up to a 265/75/16 Duratrac and keep it around 30 psi. (my door jam says 30 psi) I go up to 32 psi in the winter, since you lose psi when it's cold.

 

I'm sure your MPG is improved - at the cost of ride, traction and tire wear.

Set them (tires cold) to whatever the door card states as a minimum, you can go a few pounds higher if you prefer a firmer ride.

For a temporary heavy load you can inflate to a higher pressure to firm up the handling, more in the rear obviously, the Tacoma probably doesn't have enough payload to ever need the 44 pound maximum of the tire.
