    I'm sure there is a thread on this already, but what would I need to do to fit 33/12.5/20s on my 2015 Tacoma with 20x10 wheels (no offset)? Can't seem to get a straight answer on this, and most people are saying it won't work which I know isn't true because I have seen it done. Thanks for the help.

    10" wide wheels with 0 offset would be too much backspacing so you would need spacers. That would push the wheel out and most likely cause rubbing. The chart below shows that combo would be 5.5" of backspacing and stock is closer to 5-5.25". I think you would want to go with 8.5 or 9" wide wheels. My tires are 305/65/17 which is basically a 33x12 and with 17x8.5 wheels with -10 offset and get just a little rubbing on full lock turns. I think you want to look for 9" wide wheels with -6 offset, it would make the tire/wheel stick out about 1/4" more than mine do. That would rub more on the cmc area though.

    I guess there’s two things you can do then, either ask the people who you’ve seen do it how they did it, or bolt them on with the spacers that you’ll need because the inside of the wheel/tire will rub otherwise, and just start removing and cutting everything they hit because they’re too wide. Your choice, lol
