What size tire can I put on this wheel?

    Hello,

    I'm running this wheel that came with my 15 DC 4x4 XP. I currently have 275/60/20 Nittos on it with a 3/2 level lift. When I added that I had to bend up the ears on the skid plate a bit. Also add 1.5" spacers since then.

    The guide at the beginning of this thread, if I'm reading it correctly, says I can run 285/65/20 I assume that would require more bending.

    My question is how big of a tire can I put on the wheel and what are the cons in doing so?

    What size is the wheel? 20x9? 20x10? Offset/backspacing?

    Are you looking for the best tire you can get on there, or the biggest one that will fit on that wheel AND under your truck?

    That's the problem Ron. I have no idea. I'd like to go a little wider and maybe taller. I've been to 2 diff tires stores in the last few months and asked them and get blank stares then the comment along the lines to put the same size that already on there.

    If you are able to take the wheel off the truck, it will give you those dimensions on the inside casted into the spoke. Then you would just have to measure the backspacing. Google how to measure it.

    If you run 285/65/20 that's about 34.6". With your wheel spacer, you'll probably clear your UCA's and bending the skid plate is no big deal, but that depends on your offset. The issue is most likely going to be your body mount along with your mudflaps and front liner.

    ET 50 would be a positive 50mm offset from my understanding

    I should be ok with the 285/60 R20. Do you think the 305/60 R20 would fit without trimming?

    From what I can find on the interwebs. The Tundra bolt pattern was made in a 20x9, +35 offset.

    With your +50 and 1.5" spacers, that puts you at about a +12 offset. 305/60/20 is about a 34.4" tire. You will more than likely rub your mud flaps and the front liner. And will be very close to your cab mount.

    Based on my limited experience, I'm running a 3/1 level on 20x9 +25 combined with 295/60 and I had to remove all the front wheel flaps, heat mold my liner at the front and I barely clear the cab mount. With his spacers creating a +12 offset I'd say he would hit the cab mount with 305/60's. He might be able to squeeze in 285/60's.

    I went with the BFG K02 and the same size I had 275/60 R20. It would not of taken a bigger tire without some work in the front of the wheel well. I'm getting a very slight rub with the wheel completely turned in reverse. Thanks again for all the input.
