Went up to 265's from my steelies, what pressure for them?

Ended up putting a set of wheels with 265 / 70 / 16 cooper HT's on them on the truck and was curious what tire pressures are being ran for the 4 cylinders?

Also I have an access cab to boot so even less weight there. I tried searching, and either I am bad or it's something that hasn't been covered too many times.

Stock PSI from my 245/75/16's are 29 front and rear. Right now I have the fronts at 31 and the rear at 29, seems to ride decent but it's only day 1 on the tires.

 

32 seams about right. You can get technical and do the "chalk test".
Depends on what weight you are carrying. I run 285/75/16 @ 42psi on all 4's.
I started rotating every 3 months and its perfect.

 

It should say recommended on the tire

 

Really? That's news. Where exactly is this located?

 

32-35. Do a chalk test.

 

Odd about his tires but on my general grabber 265/70/16 it was recommended to run 44psi front/rear

 

depends on what the load range on the tire is as well.....im running 255/85-16s on my regular cab that are E rated, if i run anything above 30 in the front and 24 in the rear they don't have a good contact patch and wear the center tread.....literally all trucks and tires have potential to be different, you just have to figure it out on your own.....any pressure to someone else can " sound right "

 

Thanks for all the input on this. I guess I went the opposite direction of what I should have in letting air out. I'll snag some chalk from walmart today.

 

Sorry for the thread revival, but i had a PSI question
and this was the closest thread i could find with search...

I'm looking at BFG Rugged Terrain T/A LT265/75/16's
and the guy is saying they should be around 50psi
because they are 10ply tires?

Seems very high to me?

I'm not a tire expert, but i've been running 30/32 in the 245's on
there now and all is good.

Thanks all for any clarification.

 

Much misinformation on this thread.

The PSI on the side of the tire is the MAX psi for the tire! Not the recommended PSI for your application!

Basically, the PSI you need is determined by the weight of the truck, not by the tire you're running.

So - do the chalk test. Or just follow the recommended PSI in the owners manual.

 

See my post above. That's the MAX psi for the tire, the PSI at which it has its maximum weight capacity (which is probably your entire axle weight, not your wheel weight) You'd need that for an incredibly heavy truck, but not for a Tacoma.

 

X2.
Running your tires at Max PSI will give the impression of riding around on granite wheels a la Fred Flinstone. Less than ideal for ride quality, handling, tire life, etc.

Go with the PSI recommended on the door tag/owner's manual if you don't want to do the chalk test.

 

since you went larger than stock use more air then stock, your inside door on the driver side has PSI for each tire. I am 265/75/17 Wrangler Duratrac C rated and I use 38-40 depending on if I am carrying anything in the bed.

wears even and rides smooth.

 

PSI is a measure of "Pounds Per Square Inch" not a measure of volume.

So, if you're running a larger volume tire, at the exact same PSI, it *already* has more air in it than the small size tire.

 

I have that sideways in terms of what I meant.

I was not running the stock pressure in my newer tires and because they are totally different compound and tire type it needed more PSI to be proper for rolling without issues.

even the monkeys at say Discount tire will set your new or larger offroad tires clearly not stock to the PSI on the door and you will wander and wear unevenly unless you are replacing your tires to same ones Toyota sold on the truck.

Every tire seems a little different.

Yes BFG Rugged Trails in a 265/70/16 will be fine on 29-32 PSI or whatever the door says.

In the 6+ years I have owned this truck and others in the past like it I have NEVER used stock tires and no matter the ones I used, In this trucks case I have used BFG AT Ko's in 265/75/16 Load range E rating and it was set best at 37PSI.

Next was BFG Mud Terrains load range E same size. 37 PSI was perfect again.

Now I am on Duratracs Load range C 38-40 PSI is ideal now because:

1: I carry more weight in the bed and have heavier armor over a stock truck so I weight more per corner.

2: I am running a larger all terrain tire with totally different characteristics and design geometry than a highway tire.

 

OK, I see what you're saying.

 

Irrelevant for the OP, though, since he went from a 245/75R16 P-rated street patterned tire to a 265/70R16 P-rated street patterned tire without adding weight to his truck.
Sticking with a tire of similar design, construction, & OD without modifying the truck it would be recommended that he stick with the same PSI as is recommended for the OE tires.

 

Thanks folks.

I'll do the chalk test of course and adjust accordingly.

My tire guy said he was going to put 50psi in there to better
set the bead and i could do whatever afterwards.

He owns his own shop and has been in business for a while,
so he must have a good reason to feel this way?

Peace Owt
