    Hello, I just bought a 2018 Tundra Sport. Im new to the forum and have looked around a little and couldn't find what I wanted to know, whats the deal with Toyota's recommended tire pressure of 30psi on the 275/55/20 TRD wheels. anyone running something different for city driving specifically?

    Not exactly the same size tires but I typically run about 45 up front and 40 in the back. 30 seemed low to me as well.

    thanks, I ran mine up to 37 today (according to the dash TPM) I will probably shoot for 40 to see what kind of difference that makes.

    I usually check the sidewall of the tire for the max pressure and fill them up about 5 or so lbs short of that.

    Everyone's ideal tire pressure is different.

    Best thing to do is the chalk test.

    My load range e on 17s I run 30-35 PSI to get even wear.

    Thanks guys! I’m bumping my psi to 40 and plan on rotating every 5k and monitoring the wear. My side walls say 44 is max psi. I did see the chalk test thread and am wondering if you’ve tried it?

    285/55/20 stock ‘17 SR5 with tow and nurf bars (I think weight has something to do with it...) I run about 40psi. Stock tires for my package, that’s what the door sticker says, but yes, do the chalk test.

    There’s gonna be some members who don’t subscribe to the chalk test because wheels stretch out under centrifugal force at regular driving speeds. In that case chalk heavily and drive a small route. I like it, it’s a very easy cheap test.

    And psi changes with temperature (including temp of the tire as you drive it)
    There is no silver bullet, just guide lines to get you close to the target. It’s not perfection, just “good enough” (which my good enough may not be yours)
