Tyre calculator

[JASE-MK2]

Hi guys, here is a link to a wicked online tyre calculator and it works a treat. It will give you the difference in rolling radius, speedo difference and many other factors between what you have and what you want to fit. PERFECT if you cant make your mind up!

Both of them are good, and they both say that, you can go to a 14" wheel with a 185/60/14, and its only 0.52 or 3mm, in circumference of 1 revolution, compared to what was original, 175/70/13, all it is, is 10mm wider tyre

Its usually the width thats the issue on the rear arches I find.
