The number describe the width/sidewall/rim, and don't have any bearing on thickness. The thickness is denoted by the lettered load rating (also described by the number of ply creating the sidewall).
To simplify it. The first number is the width of the tire in mm. The larger the number, the wider the tire across the tread.
The next number is a ratio, that describes the side of the tire. If the second number is 60, that means the side of the tire is 60% the width of the tire. So a 265/60/__ tire would be 265 x 60% (or .60) which makes the sidewall 159 mm tall. The lower the number the lower profile the tire. Don't confuse this with overall tire diameter though, because rim width also affects overall diameter. The last number is the rim diameter. The rim diameter is usually only an issue when going smaller, because you need to clear the brakes and suspension. Going bigger is rarely an issue, unless you go so big you have to increase your tire diameter.
Anyway, that's the simplified version. Now you should have an idea of what the numbers mean. Regarding the look you like. I've got 18" rims on my Overland, with BFG KO2's on them (255/70/18). IMO, they look great.
