size of stock tyres in 1996 318ti E36

[lumpsta]

Hey guys.
i just bought an old skool 1996 318ti E36.
it come with 18" rims. In sydney, the law is we are only allowed 2" up and down from the stock size of the rims that come with the car.

For example. If the stock car came with 15" wheels, we are only allowed to go up to a max of 17" or down to 13".

I was wondering if anyone noes wat the stock size of the 1996 318ti rims were? im hoping they were 17".

Thanks,
Jason.
