    Do you know what they call a 33" tire in France... :p

    On a serious note, on paper the only difference is 33x11.5-17 being 0.3" wider than 285/70-17. In reality, all tire models deviate slightly from the standardized spec. Best bet is to go on TireRack.Com or the tire mfr's web site, and compare the actual tire width and diameter for your old and new tires.

    Had tons on the Taco's.... new truck is pretty stock
    That's been beat to death.... try the search function on the site and you'll find hundreds of replies to that very question.

    It depends on your wheels you intend to run. On stock, you'll rub UCAs when steering. If you pick an aftermarket wheel with too little backspace you'll rub the body mount BAD as well as the bottom lip of the inner fender behind the bumper. Most guys with 285 rub the cab mount to some extent, so most cut/box it themselves or pay a shop to do it if they don't have the tools. I sell a CNC cut cab mount boxing plate if you need one.

    Sounds good. I've been trying to put 22" on my taco with 3 inch lift. Does anyone know if it's possible to do that?

    I didn't see this mentioned anywhere, so I just thought I should mention;

    It's important to remember that the first number is the tire's section width, NOT tread width. That means that it's the distance from sidewall to sidewall, NOT from the inside shoulder to the outside shoulder across the tread face.
