yup, but as in the case of my 68 beetle (which had 14 inch rims on it) you can also got for 195/65R14 tyres which are a little smaller than stock but fine for daily use.
on my 1303 i'm currently running 185/65R15 (front) and 195/65R15 (rear) on toyota rims (which are too wide and incorrect bolt pattern) so hopefully i'll be swapping them out soon and fitting my EMPIs. the correct rim for my car should have the following specs:
size: 15 inch (max)
width: 5.5inch (max)
offset (ET): 23-34
Bolt patttern (PCD): 4x130
the above spec is also fine for any post 68 beetle.
i might have to change my front tyres as well as 185 might be too wide for the front suspension once i fit the thinner rims. so i'll probably be going for the size i mentioned in my last reply (for the front only), rears will (hopefully) stay 195 as the taller/wider tyres will help grip and also improve my overall gearing.
