285-75-17 how tall? width? pics?

does anyone know how tall and wide the tire actually is? one person said they are just shy of being a 34 inch tire but does anyone else know? and does anyone have any pics of them on their stock or levelled truck. thanks

Depending on model of tire they are generally anywhere between 33.75" to just over 34".

There's a simple formula which converts metric tire sizes into their diameter in inches. It is as follows:

Section Width * Profile / 1270 + Wheel Diameter = Diameter in inches

Therefore, for a 285/75/17 tire,

285 * 75 / 1270 + 17 = 33.83"

As mentioned by the gentleman above, there will be some variability in the actual measurement, depending on the tire.

Check out my thread in the suspension area under "Thuren lift installed w/ pics". 285/75 17 Nitto Terras. Remember, though, that the tire size will be shorter once weight is put on the tires once installed. My tires were almost at 34" and on the truck they're around 33".
