mines out nearly 20k with 32'' i just put markers on the dash. cheers ron

oh ok, so with 30's will it be major? how do i no where to put the marks tho

i got my mates gps and did 40'60'80'100k

Don't know if the vitara is the same as the sierra but with 30's on mine you have to be 5 k's under on the speedo to do what your doing! As in if your speedo reads 95 your doing 100! Hope this helps!

Thats at 100k's.
If you are doing 60k's then your speedo is out by a different percentage.

vitara on 30s run at 10% if you do 60 you are siting on about 66
at 100 its 110 AT 140 its 154

ahhhh thanks for that cheers guys

Heres a site that lets you put in old and new tyre sizes and will show you the speed differences:

It also has a few gear-related calculations there as well.

My Vitara is the same amount out with 30' tyres.
