"Dive" and "other suspension factors" I feel have nothing to do with it at all. Front End Dive is a chassis torque reaction to braking. The Telever front end does not dive-react like a conventional fork. But the front tire load under braking is not a factor of the Telelever fork or of a standard front fork (that does dive). The chassis braking torque dive reaction is a factor of wheelbase, chassis center of gravity, rider/load placement, and applied brake force. I detailed what I feel are the reasons for wierd front tire wear on Telelever equipped BMWs, especially the RS Oilhead, in my post regarding tire cupping wear.
As to tire pressure, I typically run 40 psi on the front and 42 on the rear. With the Wilbers shocks on my RS and with those tire pressures, I get very even tire wear and practically no cupping/scalloping even with 14,000 miles on the front tire. This has proved itself with three different front tire brands over three seasons and riding on the same roads and with the same loads.
For me, on my 94 RS, the one thing that impacted tire wear was replacing the worn out front shock with a quality built, properly calibrated and tuned shock. Note I did not specify a particular brand. I feel any aftermarket, rebuildable, quality shock, tuned for your riding style and riding loads will produce this result.
My theory, is that crapped out shocks (no damping action), allow the front end to "flutter" minimally, but at a high frequency, that we cannot really feel. But, it causes the leading edge of the tread blocks on the tire to compress/squirm at a high rate. This happens both during steady state riding and light braking. In fact, I feel the "vertical flutter" is reduced/eliminated during braking. This, along with underinflation, leads to increased/uneven tire wear due to tread block squirm and heat generation. Road crown, riding/braking style, twisty versus straight/interstate I feel have nothing at all to do with excessive cupping/scalloping/uneven tire wear.
