180/55? What brand of tyres?

Michelin Pilot Sports. 180 65 17 onthe rear.

the correct definite answer is between 26 and 42.

I favour 42 cause that is the answer to the universe.

more pressure = less grip less wear
lesspressure =less grip, less wear.

personal choice and feel.

Ok so sounds like 36 could be the go then, sort of in the middle.

Sounds good, thanks for that

fuckit.

that was surposed to say

more pressure = less wear less grip
less pressure = more wear, more grip.

FWIW I run my pirellis at 32/36

36 front has been a standard on a lot of bikes running the 120 - rear between 36 & 42 depending on bike, rider weight etc. 39 is smack in the middle and a good starting point for the rear!
