Just go with the manual suggestion, which I believe is 36 psi...

On my B12, ran 36 psi front always, 32-36 rear (depending on what kind of riding I wa doing). Higher wil give you an easy maintained travel pressure, 32 will give you a good contact patch for traction accelerating out of corners on twisty aggressive days.

Regardless of your preference, check it before every ride or once a week for commuters. Tire pressure is very important on 2 wheels, ya can't just adjust it and let it go for a couple months like you might a car.

I've been 'advised' by two different mechanics and a tyre specialist to run 36psi front and 40psi rear on the B12.

The 'good book' (owners manual) says 36psi front and rear.

I run 36 on the front and between 36 and 40 on the rear depending on the type of riding and the load I'm carrying.

Well "The 'good book' (owners manual) says"
33psi Front
36psi Rear
For a 1996 GSF600

36 front 40 rear
I'm about 14 stone. (But getting lighter)
Regardless of what the good book says,
Fact 1 The recommended psi is for comfort not best handling or best tyre life, it may however be ok for a little lite weight Japanesse rider. No offence indended to any Japanesse fellow riders.
Fact 2 Tyres should be run at the tyre manufactures recommmended psi.

33psi on the front of my 96B6 feels like I'm riding on 6 inches of mud.
Its not very comfortable under hard brakes, and in hard cornering you can feel the tyre flexing, and it wanting to wandering

36psi on the rear I can live with as I dont mind the rear walking around, but still it remains that 40 psi is the best feel and the best by far for some sort of tyre life.

On the ZRX I run 36-38 front 42 rear.

What are you using for the tire manufacturer's recommendation?

Not the psi cast into the sidewall, I hope. That is the tire's maximum pressure at its maximum weight load. That weight is usually well beyond the maximum weight the bike itself is rated to carry.

The owner's manual is at least a good place to start and you can adjust your tire pressure to suit your needs and tastes from there. I've been running 36/36 in my B12 and my Pilot Roads seem to perform to my satisfaction and rears will last 10K miles and fronts 15K.

When I 1st looked at using the shinko tyre, the importer gave me a sales brochure and preformance data, and it quite clearly with the weight of the bike the rider, its bia's front to rear, and the tyre size, and type of riding done suggested 36psi front and 40 to 42 rear.

I have used these as guides only, but for best feel best comfort, best milage, they must have been pretty good at guessing or they had done some homework on their product, cause I keep going back to 36 front 40 rear.

Bike owners manuals of all the bikes I have ever owned have always been way of the mark, in fact some dangerously soft.
To strenghten my agruement, I ran into a bloke I used to work with, motorcycle couriering, he now works as an instuctor at phillip island on track days. As part of the safety inspection tyre pressures are checked,
And many an arguement over the correct tyre pressure is soon finished with a firm you will put at least 36 front 40 rear or you will not be taking part in the ride day. Thats for bikes around and above the weight of the B6. So I figure someone who to a quaified superbike instructor should also know what the hell his on about. And you know some of those people who argued black and blue, toe to toe with steve, some are friends of mine, all said this and that about the bikes manufacture states this or that. But at the end of the day they ride away saying shyte the bike now handles so much better. So go figure that out.

ive put in 33/36 psi and will keepan eye onwhether it is stable at that pressure. cheers

commuting f-36 r-38

agressive riding f-34 r-35

trackday f-30 r-28

These are when the tire is cold.

That's great Mick!

I just wanted to point out for folks not to use the max pressure cast into the tire as something they should go by. Too many people believe this figure is what the tire should be run at.
