Riding the Darkside

[fatal]

I suspect that if stopped by traffic police here in Blighty you might be prosecuted under the construction and use regulations for fitting that car tyre. The insurance company also may not be too happy if you had a spill.
still have a dose for clap for  your efforts

The front original Dunlop lasted 10k miles, replaced it with a Bridgestone BT23 which lasted another 30k miles and the current front is a T31 with 20k miles with little to no signs of wear at all.

Running pressure for me all year round are :
Front =36PSI
Rear = 40PSI

Those are superb mileages.
Your front tyre pressure is quite high,Honda recommend 29psi.After experimenting with my tyre pressures over the last 3000miles since I bought the bike,I've settled on 26front and 36rear.I only ride solo and weigh 90kg with a 4kg tank bag on board and no other luggage.
The bike on original Dunlops feels planted wet or dry at those TPs,though I'm a cautious rider in the wet.
I can't see me getting anywhere near your mileages for the rear tyre as the centre section has already shed 2mm of tread(6mm new,now 4mm).I'd estimate 6000miles max for my rear before it needs changing.

Actually the 29psi from Honda sounds low to me-but it seems to work without the tire cupping-on Lets say a Suzuki DL 650 any less than 36psi and the tire would be useless in about 6K from cupping-I have taken markdarren's advice and purchased a set of T31's and will run 36F  40R and see what happens but with the fantastic mileage he's getting can't see nothing but good happening

No signs of cupping/scalloping of the tyre tread yet @ 3000miles and I've been riding at 26f 36r for the last 2500miles after initial TP experimemts in the first 500miles.
It's a nicer,comfortable and more planted ride at the lower pressures too.

I wouldn't think there would be your only running 3psi under my only concern would be bending a rim if you hit a deep hole with that skinny tire  not a lot of width to spread the load and I believe these stock tires are made for this bike and seem to be holding up  well to cupping-I'm a bit heavier than you and anything less than stock pressures the bike feels off
