C rated tire psi

Hello....have 265/75r16 cooper A/T on my taco...tire is C rated....max 44psi.... wondering what you guys normaly run your tires at? There at 32psi now.....daily driver...

 

Google 'chalk test' and then determine your optimum PSI for your actual vehicle.

Guessing your 32 will be close, but never hurts to fine tune.

 

Thanks...yes ive read about the chalk test....but just seeing what people say....

 

What does your door jamb label say?

 

I recommend you try 36 psi front and 33 psi rear.

 

Its not the oem tires!

 

Pay attention!

 

lol

I was.

 

I settled on 34 front and 32 rear when warm for that size. Pressure can increase as much as 10-15% in peak summer from cold/parked in the morning to highway speeds in mid afternoon.

I had C rated, Falken WildPeaks in that size on OEM (stock) wheels

 

If you check, and apparently that’s way too inconvenient for you, you’ll see you are 2 pounds from the Toyota recommendation.

 

Damn dude, why you gotta throw in that slam? She was asking a legit question here.

 

Well.... If you take the time to read my tires at the moment are at 32 psi... Which is what the factory recommendation is on the original tires! Since I'm not running the original tires I thought the gentleman on the line would be graceful enough to tell me what they prefer to run their tires at? Apparently that's an inconvenience for some as some are not gentleman!!!

 

I'm at 30 psi on Duratracs all around.

 

I run 35frt/33rr and adjust for load.

 

May i ask? Why the difference in front and back? Why not all the same?

 

There is less weight in the rear of the truck with no load or light load. Often this will give the best compromise of contact patch wear, traction, and ride feel.

The chalk test only takes a few mins and is the best way to optimize wear at home with no special equipment.

 

32 is fine.

 

When you say 32psi is fine....were talking when cold? Becuase 32psi will turn to 34psi when hot. Etc,etc....just to be learning correctly....

 

Unloaded, the weight bias favors front heavy. Loaded, that bias diminishes depending on weight of. Adjust rr PSI accordingly. 50/50 frt/rr ratio is considered optimal by most.

 

You will get multiple different answers from people with multiple different factors. Start at what the door placard states and then adjust from there and see what feels right.
