I reckon about 8k kms/5k miles for the rear and 13k kms/8k miles for the front. Michelin Pilot road 4's. Lovely and sticky and great cornering confidence. I ride in a sporty manner. Love fast cornering - no chicken strips on my tyres.
I had PR3's last, the rear saw 3000, the front 4500, changed when I had just about touched the wear indicator because they had worn unevenly.....an indication of my increased confidence on left handers over rights.
Currently have 800 on a pair of Pilot Power 3 2ct.....very grainy up to the edges now, which helps in the wet at least
I'm nearly 17 stone too, so the tyres do really get a fair amount of abuse, and in this part of Scotland the distance of tarmac covered in turns is probably close to the same amount you spend on straights
