Re: Tyre triangulation
cornering hard.... wears and tears the sides, the middle stays normal and you then have a triangle..
You then can have an unstable front end and head shakes. Wattie was suffering this after the P.I. ride and thought it was head bearings.. it wasn't..

Re: Tyre triangulation
Long highway running and the camber as mentioned kills the sides and makes what you call triangulation.

Re: Tyre triangulation
I think the technical term is scalloping.

jury is still out on this mate

havent done any bendies yet, but it still dont feel quite right.
those diablo corsa's are soft cath, i only been commuting, (have kishy strips like Franks) and they are furry on the front already. only about 200km on them

but yeah the bloody camber kills the right side.
jase i think scolloping is a bit different to the triangle cath speaks of.
my pilot power fronts always tend to scollop. it feels crappy and rough.

Re: Tyre triangulation
Agreed, the scollop effect is usually through low air pressures and hard braking but that is only part of the cause. Anyone that has ever seen a from that has done the Nullarbor knows what the camber does.

the tyre profile wears and goes 'triangular'' in shape
we aren't talking about the diameter of the tyre

I think maybe we should be. Can you imagine how difficult it would be to ride a bike with a Triangle shaped tyre. Much more difficult than some wimply little profile problem..
