35” KO3 PSI

[Agostino]

Wondering what everyone has the PSI at for KO3s. Door says 38 but tire shop set them to 46.

They are like f rated tires so yea .

I have my MT Bajas at 35psi all around. If in doubt follow what the door calls for.

I could only get mine filled to 99psi, so not completely "full". Maybe you can reach 100?

Most ATs should be running between 35-40 psi for daily driving but will obviously fluctuate based on temperature, altitude, etc. no reason to be at 46 psi straight out of the tire shop. Lucky for you, that’s very easy to adjust.

Thewhole story is that yes you run c load tires at 32-38 on street . But for E& F load tires ( which are more biased/ designed for HD trucks and towing btw) you are looking more towards 45-50 psi .

Look up the manufacturers table or call them. It/they will tell you exactly what air pressure to run based on load of your vehicle and what tire you're running.

I have never ran over cold 40psi personally even towing a car trailer with a full size dodge truck loaded on the trailer with E rated 35s Toyos RTs. Only thing you're gaining at higher psi is a harsh ride, worn tires, and a tiny bit better mpg.

The tired and true chalk test is another option.

You’re going to get a ton of different opinions on here but I guess the true way is to chalk test. If it’s me the factory number is high for load range C making it probably perfect for a slightly stiffer tire. I wouldn’t be running anything over the factory numbers.

Let us know what you think of them compared to the factory. Very interested but like many scared of the load range E.
