Title: Tyre pressures
Post by: 100milesaway on May 24, 2012, 04:29:21 PM
Those of you running Michelin Pilot road 3s. Do you run at bike  manufacturer recommended pressures ie 42/42!!!!!! Or do michelin specify there own? :undecided:

ive run all my tyres at 42/42 regardless of brand, seems to work just fine

although I muck about with pressures on the Tuono depending on the tempature... I have been lead to belive that 42/42 is kinda set in stone for the GTR ...stray from these at your peril.... :no:

42/42 is and always has been good for me  :cool:

I found 300/300 to be best since pounds and inches don't mean anything to me.  :whistling:

42 front and rear everytime. Anything lower and the bike feels heavy and cumbersome.

Mine had dropped to about 39 recently due to laziness on my part... but topped them back up to 42 yesterday and it felt so much better.

It's important to note that you inflate to 42 psi which means they'll be running at about 44-45 psi.

Good note .. especially when riding in this hot weather ... but 42/42/ is what I pump to  :mfr_lol:

all manufacturers inc kawasaki state cold tyre pressures when giving their reccomendations so they have allowed for 42 to increase to 44 . Ive never noticed my tyre sensors show more than 2 psi increase , even when ambient temps have been 25c+

On the PR3 I've run as low as 39/39 without issues

This is for when I want more grip in winter

OK the new bladders are on, and they had better be good after the way you lot have been banging on about them. The Michelins have replaced a pair of Dunlop Pilot road 2s, which were still legal regarding tread depth, but had deformed badly which made the bike feel awful. Mileage for the Dunlops 4250, mileage for original Bridgestones 5000. So lets see what the Michelins can do :undecided:

Interesting Mr Viper .. in the deepest of winter my TP's show, when leaving the garage at 39/40 ish or there abouts ... so often lower ...and don't change for the trip to London or home .. I just put that down to cold weather, cold rain in contact with said rubber and freezing tarmac... but the PR3's are always a good ride.

i find the same when its cold , in hot weather it does rise , but never more than 1 to 2 psi, all given pressures are always cold, cars ,van, trucks , hell even the sex doll is filled when cold  :sweatdrop:

So seriously,
                   I pick up my GTR tomorrow on a 09 plate, first time I have ever owned a Kawasaki.

                  I have been looking at this site now for a week or so and have noticed you writing about this tyre sensor. How does that work then on the dash ?

The dash in front of you can show all sorts of parameters, just behind the left hand grip is a button you can flick to go between the different displays, tyre pressure front and rear, battery voltage, average mpg, current mpg and other stuff I can't remember, I always leave my tyre pressure display on so I can see if one is going down, like it did in Belgium a while ago.

The TPS sensor transmits using wireless to the EC which then submits the info to the onboard display using the CANBUS

Both the front and rear tyre PSI are displayed. The TPS isn't accurate so you should use a calibrated tyre pressure device to ensure you are at the correct PSI. However, the TPS tends to be about +1 PSI out. The values increase as you ride due to the tyre (and consequently the air) getting hotter.

It works well.

Hi

On the left handlebar is a lever/button at the front which will when pulled towards you will cycle on to the next bit of the multi-function display - the display includes Battery Voltage, Outside Temp, average mpg, current mpg, remaining fuel in miles left and finally the TPS readings front and rear tyre pressures

Kind regards

Steve

Been riding today when the outside temps were 30 -31 degs, the rear tyre pressure as shown on the TPS was 42 when cold, as the temps rose through the day it never went over 44 psi mostly it was 43.  high speeds and tight corners, so tyres were getting plenty of use  :whistling:

surprises me that the tyre pressure does not rise more in these conditions

I believe the various compounds, I think silica is the key one, they use in the tyres are designed to keep the tyres at a constant temp/pressure - regardless of how hot/cold the outside temp is or how hard you are working the tyres.

Hi Trousersnake,     Ignore the smug posh people with their 2010/2011/2012 GTR's. Us normal folk with the 07-09 Classic GTR do not have this h/bar toggle. We have to shuffle forward and reach between the clocks (while swerving all over the road) and use those buttons to scroll through menus, be aware that the TPS does not display at a standstill !!! You will have to start moving (then the ABS warning light will also go out).  Hope you enjoy your GTR

Coman
