is this a real question? look at your tires and they will tell you..

too low will eat mpg's and too high will do the same but give you a rough ride...

 

All your going to find there is max inflation and load carrying capability. Chaulk method will get you a nice street pressure.

 

Google.

 

It really depends on the type of tire. Is it P rated or an LT tire. IF it'san LT tire which load rating.

My tires for instance. When I ran the P rate P265/70/16's I ran 35psi frontand 32psi rear. Gave me a rice ride, as decent of handling as I could expectfrom an AT tire and over 60K miles before they needed to be replaced.

My current setup is LT265/75/16 C load Duratrax's and I'm running 30psifront and 26psi rear. I've done the chalk test and I contact patch across thetire. If I run more than 26 in the rear I have substantially less traction inthe rear as my contact patch is only about 2 inches wide and I'm riding on thecenter of the tire.

I don't recognize those tires so I can't tell what you have by the picture.

 

35 PSI and rotate every 5,000

 

They are mt tire.

 

number on tires is just a max pressure. best to start at car manufacturer recommend and then do the chaulk test from there

 

Is this a real answer?

 

Great reply, I have the same tire/size as ur running and I was inflated to 35 all round. I'm going to deflat to 30 / 26... Thanks

 

Thank you. Keep in mind that my truck has a shell on it full time but the bed is mostly empty. I f you carry stuff then 26 might not be enough.

Chalk test and be done if you aren't sure. Every tire will vary slightly per vehicle. I find 32 psi works well with my KM2's for what I do with my truck.
