    2015 Tundra TSS Off Road
    Hello all,

    I'm trying to work ahead on some suspension and tire upgrades. My truck only has 15k miles on the stock tires but I'm trying to research ahead of time so that I will be ready when the time comes to change tires. What I'm looking for is three things:
    1. Slight lift
    2. Level
    3. Tires that will fill the well and sit flush with or just outside of fender flares.

    I've got a 2015 TSS off road 4x4 and would like to keep the 20 in wheels that came on it if possible. What would be the best route to achieve above goals?

    I can't speak to the question of "best" as I've only tried one setup. I have the 3/1 Rough Country spacer kit (with Diff Drop). Shoes are 285/65 R20 KO2's. I'm mostly happy with this setup, but I'm thinking of putting a stiffer sway-bar on the front from a Sequoia and a TRD rear sway bar. I have more body roll than I would like.

    General consensus seems to be to stay away from spacer lifts if you are going over 3" and/or you intend to do any moderate to serious off-roading.

    There have been several reports of failure of front struts due to leveling spacers (some of these were from simply going over a pot hole). Then again, there are some members who have been using spacers for years without an issue. General consensus. however, seems to be that spacers make the truck less capable (on and off road) than stock. (People get them for looks)

    If you want to use stock wheels and have the tires to poke out beyond fender flares (I am assuming pocket style ones), you will need some wheel spacers. If you make them poke out too much, you will have rubbing problems (which limits the size of the tires you could install), unless you are willing do some serious cutting.

    For lift I highly recommend going with a new coilover lift. This can be achieved with a Bilstein 5100 front shock that has set adjustments to give lift. This will level the truck ~2" up front.
    Or go with a fully adjustable coilover like the Toytec Ultimate or Boss kit for a 3" front and 1" rear lift. I run the Ultimate kit and like it a lot. No issues.

    Your wheels have +60 offset. You need to be around +20 to get to flush with the fender with 11.5-12.5" wide tires. For this you will need 1.25" wheel spacers. Spidertrax and Bora are the top brands. I run Spidertrax without issues.
