    Tire PSI question

    Greetings,

    I've spent the past 30 min looking for an answer to this and I've either found it w/o realizing it or I'm not looking right... anyway

    I got new wheels/tires for my car. I was at 235/50ZR18 for all 4 wheels and now I'm at
    255/40ZR19 x2 front and 275/35ZR19 x2 rear.

    How can I find the recommended PSI for this new setup? There's nothing on the tires themselves (just max psi) and all internet searching points to 'look at manufacturer sticker inside your door'. Does the info on the sticker mean any/all tire configurations for said vehicle? If so then I have my answer but my limited tire knowledge would make me think it changes depending on setup- maybe not.

    Pls halp.

    Somewhere between 32 and 36 for most cars. Trucks are generally between 32-40 unless they have lt tires. Slightly higher psi will get you better mpg. Wouldn't go over 40 for cars.

    32 - 36 is fine. Typically you can also Google the tire itself and find out. Don't go over 38 imo.

    Ok, sounds like the conclusion about the door sticker being specific for car standards is what to go with. They're inflated slightly over but nothing out of acceptable. Thanks!

    100-145 if riding a 700c tire bicycle
