So, I have a pretty custom cafe racer from the 70's which I've modified with modern paralever suspension, a gsxr front end (slightly more unsprung weight at the front) and slightly wider and better performing tyres.
I typically ride a few times a week, and that's mostly hills runs.
The question is, how do I work out what my optimal tyre pressure is? Is there a method for calculating it, or is it just done off what the tyre manufacturer recommends? I've been running around the mid-low 30's cold front and rear, which seems OK.
