But you said it was the steering geometry that was the issue...

So which is it?
When you lean a bike over with a wide tire, the contact patch gets farther away from the centerline of the bike the farther you lean. The bike just wants to center up, that's why the steering effort is greater (just like with a freakin' car tire, except with the car tire it happens instantly not gradually).
If the tires are a reasonable width the contact patch of the tires stays close to the centerline of the bike and the bike is neutral in corners. Traction is a function of pressure/weight per square inch of the contact patch and the rubber compound (call it friction). A wider tire can have LESS friction.
16" tires have a higher profile/sidewall and more flex to the carcas and cruiser sizes offer few radial choices... where 18" tires are low profile and stiffer with more choices in radials.
Personally, I don't think handling suffers until the rear tire exceeds 200mm wide, or until Metzelers are mounted, whichever comes first. LOL
