what tyre size for 15x5??

hey all..
i recently aquired a set of 15x5 wide 5 lug and am wanting to know tyre sizes for front and rear for early beetle..
i suppose 145/15 will do the trick up front but for the rear any suggestons pls..?
maybe a 185 or 195/60 ??/ 15 up the rear??
something lowish i suppose to hold the road at speed would be preferred..
would like to get some ideas and reasons if poss and pics would be sweet as well pls..
cheers paul

I have run 205/60r15 on 5.5inch rims, so could probably get away with some 195/60 or 195/65's on 5 inch rims. personally I would go bigger than 145's on the front maybe some 185's but thats my preference, depends on the look you want.
