I have a 150/80/16 in my 1990 Evo. To get it in I used a later spec narrow belt and rear pulley. I have read that a 150 will fit, if you use a narrow spacer behind the pulley. Go over to the Evo forum and take a look over there, there is a recent thread on this.
A 150 is the widest we should use on a stock 3" rim. Another thing to consider is that on my bike the tyre is dead centre, but a very close fit in the fender! A wider tyre will not go in.
