Question tyre presures

I have read so many peoples opinions on what the tire pressure should be on the road on a 120/70 17 (front) and a 180/55 17 (rear).
For the rear I have heard anything from 29psi to 40psi. Is there a definitive answer to my question as to what the presure should be Front and Rear, for road use.
Thanks

They can be different for different tyre makes and even the different versions of the same tyre, hence the confusion.

It's always best to check the manufacturer's recommended settings for that particular tyre and use that.

Here's some links:

Thanks Antonye

I have had a look at these, I have BT014 which according to Bridgestone should be 42psi at the rear and 36psi in the front, this seems really high, does anybody else run BT014's.

Thanks, I had a look, and your right, that's what it says, but the actual tire manufacture says 36psi front and 42psi rear, so I would think that Bridgstone know best, as they built the tire.
So what do you do? do as Ducati say even though they don't know what tire you have on the bike, or the people that tested and constructed the rubber you do have on the bike.

The bike's handbook assumes you have OEM tyres, and so gives the recommendation for that particular make and type.

Always start off with the pressures recommended by the tyre manufacturer for the type of tyre you have (always assuming that the tyre is suitable for your bike!!). You can then fiddle around the margins to find your optimal pressures.

the suspension set up block at Hottrax trackdays told me that the rear should be slightly lower than the front, not higher.

For trackday's, yes the rear is always lower than, or the same as the front.

On the road, the rear is always higher than the front.
