265/275 is the diameter or height. the 70/75 is a ratio of something to something i think im not sure.
but 285 is 33" so 275 is about 32" 265 is 31" i think
someone correct me if im wrong.
btw, I'd get 31s they look good without a lift. 32's if you can fit them. you should be able to, but it might be really close, or maybe rub a bit.

265, 275, 285, etc. is the width. The 70 or 75 is a percenatge of the width that equals sidewall height.
265/70 = 31x10.5
265/75 = 32x10.5
275/70 = 31.5x11
285/75 = 33x11.5
My wording on this explanation sucks, sorry.

yeah that doesnt make any sense. 70% of 265 isnt 31"
you do sound like you know what your talking about though.
shark, why dont you go to some tire store and ask them some questions??

The 265 is the tread width in mm's. the 70 is the sidewall height expressed as a percentage of the tread width. So the sidewall height x 2 + the wheel diameter equals the total diameter of the assembly. Some of the tire mfg sites have a more complete explanation and all have charts showing the tire diameters for the different sizes.

The obvious problem in my answer above is the tread width/sidewall height is metric and the wheel size is in inches. So I just use the charts.
A wider tire could give you less mileage than a narrower tire due to friction, but traction could be better.
A taller tire will go farther in one revolution than a smaller tire, taking you further at the same engine rpm. But this may be offset by using more gas if the engine lugs due to the gearing.
Since I have never done a direct comparison of any of these conditions, I don't know what your actuals will be.
