just in case anyone wants to know 285 is the width in MM the 70 is 70% of the width for the wall height and of course the last is rim size so.
.70 * 285 = 199.5 (there is 25.4 mm in an inch so 199.5/25.4=7.85)
Okay this 7.85 is just one half of the tire, from the rim out, so you will need to times this number by 2.
7.85 X 2 = 15.7 inches
Now the final step add the rim size to the sidewall and you are done
15.7 + 16 = 31.7 this is overall diameter of a 285 70 16
I am hoping to get 295 75 16s next tire purchase
