PSI for 285 17s?

Hello I'm running 285 17's wanted to know who's running these and what psi? Thanks.

 

Chalk test.

 

What tires? And load rating?...I'm running 35psi on 285/75/16's bfg ko2

 

I'm running same set up- i think its 35 psi

 

Yeah I have the same expect 17 inch. Thanks for the advice

 

I tend to stay around the psi it says on the door sticker. I like a softer ride so i keep em around there. But its all preference really, as long as you stay in the recommended range of the tire its all good. If youre worried about wear the chalk test like mentioned above is a good trick. For mileage purposes when ever i go on a long drive/trip ill max em out usually to minimize that rolling resistance. But when i get home i air em back down for comfort. The load range of your specific tire will play a role in all this as well!

 

Did you know there is a full inch difference in those two tire sizes? I used to think with those metric tires it would be the same size just a bigger wheel, like a standard sized tire would be, but its not. The wheel size changes everything in the metric sizing world. Thought id throw that out incase you werent aware. Ive always ran standard size tires so i didnt learn this until just a couple years ago, lol and im 31! I think who ever came up with that sizing system should be slapped, it makes it pretty damn confusing!
