My bike came with Pirelli Angels on it. The tires have never felt "right" to me. What psi are you guys recommending for these tires?

Well, no more than the max allowed printed on the sidewall.

I think a good average here ranges from 34-38 front and 36-40 rear. It would be a good place to start.

Just remember that the numbers in the manuals were for intended for Bias ply tires when the bikes were mfgd. Not the radials that many are using today.

Try 36 Front 42 rear, seems common spec for radials.
Look on tyre (tire) manufacturers website for their recommendations for your bike.

I run 36/39 as I'm a lardarse, however I don't reckon there's a servo gauge that's closer than about 5psi anyway so it's probably a moot point!
