4x4 Tyre calculator

[pbk1776]

Hi All

I noticed a lot of people asking of Tyre Sizes from mm to inches - will it fit, how is it going to look like and how much height difference it will give.

I stumbled on this online calculator in UK and not sure if everyone is aware of it - however I thought about of sharing it to everyone so they can do calculation themselves without repetitive threads popping up

here is the link very handy and it gives visual difference of tyre sizes from original vs to the one you aiming to get

hope this benefit everyone from this forum

Its cause most people are to lazy to do the 5 second conversion with microsoft calculator

ie: 33x12.5r15 =

• 33*25.4 = 838mm
• 12.5*25.4 = 317.5mm
• r15 = r15 no surprises there

its a tad harder converting back to inches from a 265/75r16 but this is all you do.

ie: 265/75r16 (265 is the tyre width and 75 is the aspect ratio of width to wall height its 1:0.75 in this case r16 is just the wheel diameter in inches..again no surprises there)

• 265*.75 = 198.75mm (this is your tyre wall height)
• r16*25.4 = 406.4mm
• sum of the sections
• =198.75*2 (upper and lower walls of the tyre) + 406.4 = 804mm
• 804mm/25.4 = 31.7"
• 265mm/25.4 = 10.4"

obviously these figures change per per tyre manufacturer but the method of converting to and from remains the same.

cheers
