    First let me state i know nothing about truck tires. I just bout my first truck this past weekend!

    ok since thats out of the way, i am looking to replace my stock p245/75r16 tires on my 05 tacoma SR5, TRD. What is the largest size i can put on these stock rims?

    Would it even make sense to go bigger? Would a larger tire make a noticeable difference in how high i am riding in the truck?

    Are there any pictures out there of larger tires on stock rims?

    Would i need to get a 5th tire of that size to replace my spare or can i get by on the smaller spare tire?

    Not yet,
    If that's what you want to do it makes sense. I've actually considred it myself. I've seen a few truck on here set up like that. look through the photo galleries. It would probably be best to go ahead and change the spare as well.

    there is a tire size calculator sticky at the top that will tell you the difference between the tire you have on now & the newer one you are considering.

    It is very easy just plug in the numbers.

    I'm not sure on the size you can put under the truck.

    As far as tire sizes go:
    The first number is the tread width (245mm on yours)
    The second is sidewall aspect ratio: (75% of the width on yours)
    and the third is rim size.

    If you increase the first one you will have a wider tire. If you increase the second one you will have a taller tire and both at the same time will give you both effects.

    I've got a set of 265/60R17s on my truck stock...so you can go at least that large (or the equivalent on the 16 inch rim.

    And yes...You should get a tire to match for your spare...but if you don't go TOO much bigger you could probably by fine..

    Welcome to the board!!
