Hi Rob,


Just took down the following information from the front passenger side tyre.




ISSR14C spr m+s


102/1005 104N










Hi Eddie .
where you have the 14c there should be some more numbers before that
for example 195

Can you tell me the wheel size or how to measure it?

Hi Eddie .
sorry for the delay "Sunday chores" .
Many thanks for the positive feed back.
The wheel size
for example
185 65 15
the first measurement 185 is the width of the tyre across the tread in mm.
the second measurement 65 is the height of the tyre from the rim to the tread in mm.
the third 15 is the internal circumfrence which is the wheel size.
if on your tyre there is no second measurement then it will be the maximum of 80mm.
hope this helps
