    I'd like to start a thread where people can post their wheel and tire setups to show off and help people decide in their next wheel setup.

    Just like the other threads of this nature, it would be helpful to include as much info as you.
    Your model vehicle
    Wheel specs
    Tire specs
    Any suspension modifications or body modifications needed to run your wheel/tire setup.
    How your truck handles/feels/ anything else you wish to comment on

    Unfortunately, I have no idea what wheels are on my suburban and I haven't removed them yet. I got her with a mismatched set of tires and I'm due to get new tires.

    [​IMG]Geneva suburban by

    1990 Suburban V1500. No suspension mods,its probably all original suspension, has running boards, factory 4x4 height as far as I can tell.

    Front Tires
    BFG All terrain T/A 31 x 10.5 R15
    Notes: Tires got inflated at 40, 45, and 50 psi and felt the same.

    Rear Tires
    Michelin LTX M/S 31 x 10.5 R15
    Notes: Tires were only inflated at 50 psi. These are super bald, as if the previous owner did burnouts with this thing. Rear end kinda looks like it's sagging, see how the truck looks level in a driveway that's angled downward?

    1975 Sierra Grande - US Wheel 15x8 Slots with BF Goodrich KO2 33x12.50x15. Pro Comp 2.5” lift with added Pro Comp Dual shock steering stabilizer. It felt a little loose after the lift and tires that’s the reason for the steering stabilizer addition. 1EC57777-3D75-4693-B032-AF5FF51E66A0.jpeg

    doesnt having the rear same/wider than the front cause tracking or driveability issues?

    No, no issues at all. The track is still a little narrower than the front and this fills the wheel opening much better. It’s an easy mod that makes a big impact.

    " Both versions had a front track width of 65.8 inches and a rear track width of 62.7 inches." - 87 GM Pickups for example. They come from the factory 3" narrower in the rear.
    It's very common for vehicles to have different front and rear track widths and performance cars with staggered tire size. Think duallys as the most extreme example.

    yes im saying he put spacers in the back, probably making it wider in the back.

    I've heard that repeatedly for many years. But I've never really heard WHY. Why have a different track front vs rear? I had a 1993 Audi where the rear track was wider than the front. Then I bought a 2000 Audi and it was the opposite. Front was wider than the rear.

    What is wrong with having the rear tires follow the same ruts as the front? The best I've heard was so "the rear tires can get a different bite than the front".
