very little difference in height between 18" and 20" WHEELS
The reason there is little difference, at least in that case, is because the number after the slash tells you the percent in aspect ratio height of the sidewall.
So, on a 265 tire, it is 265 mm wide, and 60 % of 265 is 159 mm in sidewall height (in the case of the 265/60R20)
If the number is 70 %, indicating, the sidewall height will be bigger (185.5 mm in the case of the 265/70R18)
Any tire below 65% sidewall to width height is generally considered a "sporty" tire, usually for racing ricer wannabees or those who generally have a wish for a firm ride.
There is absolutely no reason on a tow vehicle to have low profile (lower than 65%) tires. If you wanna get babes, there are much less expensive ways to do that.
I hope those guys who flipped that truck get sued for all they are worth (which is probably not much).
You ought to let GM and Ford know of you're infinite wisdom in designing HD truck tires.
