Two things first:
1) To me this is a Technical subject so sorry if it needs to be moved.
2) The discussion is not intended to be a pi$$ing contest, but more a general sharing of tire wear knowledge as it applies to motorcycle tires. Please keep it that way.
Waldo, thanks for the write-up at http://www.rattlebars.com/tirewear/
In the write-up you do state that it is not a Scientific study, but rather results from actual experience. Based on that, I'd like to get input from yourself and others on cupping (a.k.a. scalloping).
In the "Waldo" article it suggests that using higher air pressures will reduce cupping, but nothing will eliminate cupping. This may be why many folks will utilize pressures of 40psi (or more) in the front tire when 36 psi is the recommendation. The article further states that cupping is not a sign of bad suspension parts.
To add to this confusion, there are members running a G709 with stock suspension and those with upgraded suspension and neither have cupping (in my case-suspension upgrade, 36psi, no cupping).
It seems to me that since cupping appears the be caused by the tire "bouncing" on the road, that suspension would be a prime suspect, but maybe not
Everyone please chime in with their thoughts, and, try to give reasoning for your thoughts.
TIA to all for your replies.
