[Healeys] BJ8---Tire Question

[tomfelts at windstream.net]

It's time to re-tire the BJ8.  I'm looking at the Vredesteins----165R15 or 185R15.  I also will be buying new wires.  Was thinking of keeping the 5" wires.  

Question---Which of the two listed tires fit best on the 5" wheels?
           Should I get the wider wheels and a wider tire?
           If I get the wider wheels, how much rub do you get on the car--inner/outer wells?

I've heard great things about the Kumho tires as well, but I like the look of the Vresestines better----plus I have been using them on my E and love em.

TIA
Tom
