Although originally fitted with Dunlop tyres I prefer Michelin Macadams which I believe give better grip and wear well.

I expect to get around 6-9,000 from a rear tyre and maybe up to twice that from the front.

If you are experiencing excessive steering shake it is often worth replacing the front tyre.

The front tyre size is 110 x 80 VR18 and rear is 150 x 80 VR 16

Tyre pressures vary depending depending on load and country of origin
The manual suggests 36 psi for the Front and 41 psi for the rear for most countries
Michelin once told me to try 32 psi in the front and 36 psi in the rear (presumably only for their tyres).

The following table shows the rate of tyre wear I have experienced over the many years I have been riding GTR/Concours bikes. The average rear tyre lasts 5,745 miles and a front one 9,954 (somewhat distorted by the amazing 17,848 miles from an early Avon front tyre - I only changed it because it was beginning to perish!

There doesn't seem to be a conclusive winner in terms of longevity (mainly because so many of the tyres have been Michelin) - I can say I have found the Macadam 50 to be particularly prone to wear (but then they are much cheaper than the 90/100s)

Date Fitted - the Year and Month the tyre was fitted to the bike
Type - As much information as I have - I didn't used to note the particular type of Macadam
Mileage - The number of miles the tyre covered before being changed - on its own this figure does not give a good indication of tyre life as sometimes tyres are worn out when changed and sometimes they are changed early (before a major trip perhaps)
End Condition - milimetres of tread left
Miles/mm - a guide as to how well the tyre has worn - a high figure is good - this figure is calculated by taking the final tread depth in mm from the tread depth when new and dividing the mileage covered by the tyre by this "tread used" figure
