I'm not thinking anything, don't put words in my mouth.
235 mm
235 / 25.4 = 9.251968504 metric to sae
9.251968504 x .75 = 6.938976378 section width times aspect ratio
6.938976378 x 2 = 13.87795276 two sidewalls
13.87795276 + 15 wheel = 28.87795276 written sidewall height
Now measure that combonation installed a vehicle and it will probably be anywhere from 27.5 to 28.5 inches. Radials bulge and that is the exact, accurate rolling height, not what the sidewall says.
So unless you can accurately pinpoint what speedometer gear I could possibly install in my truck to make it read accurately, BUTT OUT!
Seriously man, you don't know everything, and even when you are proven wrong you consistently keep harping crap. Knock it off.

Maybe take some anger management classes
I posted a link to a calculator earlier so you could figure it out yourself
