I think you can get 265/70(same width, slightly shorter) or 260, 70-75.
That sizing system is reffered to as P-Metric. Basically, what those sizes mean is width/aspect ratio/wheel diameter.
The width, I believe, is measured in mm?
Aspect ratio is in relation t the height, its the % of height in relation to width. So 265/70 is shorter than 265/75, but the same width.
Wheel diameter is.. well pretty straight forward :P
Do you have 15 or 16" rims stock? I'm pretty sure most of the P-metric sizes larger than stock are for 16"+ wheels, so you would probably want a 31(height)x10.5(width)-15(wheel) tire, that is assuming you have 15" wheels.
