ZZ-R1100 tyre pressure advice...

[Malc]

I'm confused as to the correct pressures..I run Battlax BT56, 120/70/17F and 180/55/17R. I have 42psi rear and 34psi front, but have been told by two seperate bike riders it is too high, and by another the pressures need to be higher...
After a spirited ride (the hill leading from Paraparaumu(ish) to the Haywards hill road), both tyres were scuffing up well, and the chicken strips were well and truly untouched...
So is this a sign the pressures are ok? I am 110kg if that is any use.
I do notice the bike wants to "fall" into corners, but feels very stable.
Any tips/advice? I'm after the best compromise between grip and trye life basically...
cheers!

If anything, your front tyre pressure is low. The rear seems about right. As a comparison I run 36PSI front and 40PSI rear on my RF900 which is probably a bit lighter than the ZZR1100.

You can find the Bridgestone OEM Fitment guides here, but they don't seem to list recommended tyre pressures.

The Metzler and Dunlop fitment guides both recommend 2.90BAR / 42PSI front and rear for their tyres on a ZZR1100.

I'd try increasing the front tyre pressure 2PSI at a time and see what happens to the handling. Low pressures may cause the tyre to overheat and shorten its life.

Yea 36 F 38R don't forget these will gain approx 4psi when hot
So hot the Front would be 40psi & Back 42 psi which for a big bike like the ZZR would be about right >PS buy a digital tyre gauge so you can check them after using Airline <.

I usually do 41 F and R, seems to do the trick. If I could tell what +/- 2psi did to my handling I'd be getting a sportier bike.
