    Question tires on AWD cars...change one means change them all?

    So my gf told me that her mom was told by Les Schwab that if you change one tire on a Subaru, you have to change all of them b/c it's all-wheel drive. Is that true? I came from owning only FWD cars so that concept is a bit new to me. It make sense...sorta but not entirely. So is that true?

    The owner's manual specifies the maximum allowable variance between diameters.

    ive heard about that too. but i dont think it is necessary. I dont think it would even affect the car at all. unless its a big difference in size ie: 18 inch wheels vs stock 15

    ^^^ All Lies^^^ Listen to what SD_GR said. When I got my WRX one of the tires was a diff brand/tread life. You get a weird "knock" in your suspension when going over bumps and such.

    Edit: I love his bike though!

    Also can cause damage to the differential unit.I think a 1/4" is the maximum allowance between sizes.You can shave the new tire down instead of replacing all four.

    the reason behind the possible damage is that all wheels are drivin wheels... so they are all connected by the same drivetrain. thatis in turn means they are all doing full rotations at basically the same rate. throw a different outside diameter on there and that wheel will be rotating faster or slower depending on the size than all the other three... = bad news for the differentials.
    yup
