    Default will 285s fit stock on a GM half ton?

    looking for new meats for the truck. its an 05 GMC quad cab 4x4. stock size is 265x70r17. (they are P rated tires too. terrible) want to put a bit bigger size on but not sure they'll fit. not interested in playing with suspension aymore. would like to throw a 285x70r17 on there but don't know if they'll fit.
    if they rubbed the front bumper thats fine, i can cut the airdam to clear em. just worried about the inner fenders and upper fenders.

    That should be the max you're able to do at stock height.

    i was thinking of just jacking the keys up. but not much more than an 1" to level out the truck a bit.
    when/if i do that two questions:
    will it suck ride wise, (ive never owned IFS rig before) and will it kill balljoints/CV axles due to the increased leverage on them? and
    2: will i need to get her realligned?
