Installed 3/2 lift. Would like to go bigger than 265/70R17

So I just finished installing a 3/2 lift on my 11 double cab. I have 265 70 17s in the KO2s but want to go bigger. I'm on stock rims and would ideally like to stay there and not use wheels spacers. I'm hoping to go up to a 33. What size should I get?

 

You have a sport or sr5 ? If those are the wheels you have then 255 80 17 will get you to 33s.

 

I have just the basic TRD. With 17s.

 

Mind that narrower tire on rim border is more from ideal then wider tire.
265/ 70 ideal rimmwidth is 8 inch
But is "allowed" between 6.5inch and 9.0 inch.
I made a rimmwidth calculator, after hearing out a tiremaker. Is also dependent on aspect ratio( hight/width division)

My idea that ideal rimm ( measure rimm) is when rimm is as wide as treath, apeared to be right, only grooped.
Treathwidth is also dependent on aspect ratio. /80 treath 71% of section width.
/75/ 73%
/70/ 75%
And so on every / 0.5 / 2% more
Is for personscartires.

So if you plan a size first let me calculate if it is officially allowed. And try to find your rimmwidth, sometimes when you take the wheel off on the inside.
Copied the 8 inch filled in, is not rounded given tiresizes, you have to do that yourselfes. Example 285/80 would be ideal for rimmwidth 8 inch too.


rimwidht 8 inch
aspect ratio / smallest tire SW / ideal tire SW / widest tire SW
80 233,6 286,2 327,7 mm
75 233,6 286,2 327,7 mm
70 233,6 270,9 327,7 mm
65 220,9 270,9 298,8 mm
60 220,9 270,9 298,8 mm
55 220,9 250,9 298,8 mm
50 220,9 250,9 298,8 mm
45 211,7 239,1 260,5 mm
40 203,2 225,8 244,8 mm
35 197,3 225,8 244,8 mm
30 213,9 225,8 244,8 mm
25 209,5 223,3 236,3 mm

 

Ok so I think my options are a 285 70 17 or a 255 80 17. But I'm not sure

 

Both sizes are within what is allowed, assuming you have 8 inch wide rimms, try to check that.

And you have to do with what is on the market.
And its yust what you want to achieve with the change, higher on the wheels or yust fuller look.
