Hi Angus.
Your tyre usage at the rear will depend on how heavy handed you are on the throttle and tyre pressures if you're carrying a pillion. If your combined weight plus gear and luggage exceeds 220Kg, I'd run about 37 front and about 44 rear.
If you find the bike understeering a little, add a pound or two more.
My Pilot Power on the front just just over 10,000Km's but it was really "gone" about 1000Km earlier as it just didn't want to steer well despite having usable tread. My Pilot Power rear got about 5500Km with one-up riding only (but I'm a big guy).
The Pilot Road 2 on the rear now, has over 5,000Km on it and it looks like it has another 3,000Km if I'm lucky, maybe more.
