Mentioned elsewhere, got some Shinko's from Jake Wilson - $240.00 for front and rear - ordered, paid (PayPal) & delivered in five working days. Removed and refitted wheels myself, local tyre dealer fitted tyre to rims for a slab of VB.
New Shinko's better than old Bridgestone's (OEM), only got 8,500km out of back one, 11,000km out of front one.
Badly feathered (?) scollaped (?):
Went out of shape very quickly:
I put this down to shyte tyres, lots of km's towing the trailer, and AWESOME power of the Mighty ST1300.
The flat band around the circumference might explain why the handling was a bit "off", now much better.
Nigel, Hendo, I'm ready for some more gravel roads now.
