[Ducati] Tire Pressures

[mike major]

It sounds odd to me to have more pressure in the front than the rear as the
rear Carrys most of the weight etc.  I use different pressures with
different bike/tire combos, 36 rear, 33 front on my ST4s with Metzler M3s,
30 rear 26 front on my BMW with bias ply Bridgstones, etc. but they all seem
to work better with more in the rear tire.  To me feel, experience and tire
wear patterns are what I use to determine the best combo.  but in general
the modern radial tires seem to need more air than the bias plys used on my
older bikes.  Later, Moonbeam
ST4s
R100RT
T500R
CL350
