Well, the debate continues. Ron is quite right, I have achieved over 20 000 km from front and back. The front still had plenty left, but was a bit scalloped so I replaced the pair as a set. I have gone for oversize this time 130 on the front and 160 on the rear (Gold Wing Combo) and expect to again get well over 20 000 km. You can have a look at them at Busselton. I have found the handling fine for general commuting and touring use.
