Bonneville Tyre Pressures

36 front 42 rear?

 

As far as old tyres are concerned, think its going to be more how they have been stored. If they have been in direct sunlight for a long time and show any signs of cracking on the tread or sidewall then I would replace.
My lad has only just changed his O/E tyres on his 2005 Multistrada and they were still sticky enough. Also bear in mind a dealer can have 'new' tyres in stock for several years prior to sale. I ask to see the manufacturing date stamp when buying if there is any doubt.

 

my 07 manual says 33 front 38 rear (psi)

 

I ran my 2005 T100 at 33/37 for solo riding. You only need more at the rear to compensate for load.

Tyres age more rapidly in bright sunlight (UV radiation). Six years is getting a little tired. I found Michelin Pilot Activs the best current replacement in OEM sizes.
