Tyre pressures

[MikeyC]

Havent checked mine for a long, long time...

Need to check them tonight, what psi should they be reading? I never carry a pillion if that makes a difference.

It all depends on your tyre and the weight of your bike and load your carrying.

It should say the maximum inflation pressure on the side of your tyre.

Would probably help if I actually took a look

mikec106,
Halfrauds digital Pressure guage accurate and bullet proof.
Had mine under the seat of three bikes. Small enuf to fit on the valves of stupidly designed rims too. About £5.00.
($10.00 to our US cousins who are reading this.)

Within 3psi of tyre manufactures spec for bike/tyre will be OK but up to your individual taste and riding style, if you have 'style'.

I ran with 5psi in a T/cat for two days (so did my bro.) never thought to check the pressures.
It was a bit lumpy on fast bends. I must have looked like Rossi sliding the back end in. But not as handsome some might say.
I had a puncture but 'Slimed' it and ran it to destruction.
Scottish thrift we call it.
Hope this helps.

What noticeable difference will there be if the pressure is lower than it should be?

The gixxer is my first 'big' bike, so everything is still a learning process for me.

[Walloper]

Cornering stability and possible damage to side wall if tyre pressures are too low/high.
Too high causes O/heating.
Why for 'track days' you can drop the standard 2-3psi to warm up the tyres faster. But you are constantly on the limit so pressure gets up to normal.
Too high a pressure pushes the centre of the tread onto the road and produces a narrower 'footprint' less grip.

Tyres pressure are supposed to be set when tyres are cold.
I've never tried setting cold riding till warm and checking.
It is better to do it cold as compressed air used to inflate will be cold and would upset a warm tyre.

The manufactures have been dicking with tyres for years so do know best.

The 'Sages' of this forum will know doubt know better than me of course.

Also try and use Nitrogen to fill your tyres as it is clean and has no moisture content. If you need to be picky.

I am a W4nker. Too LOW pressure will cause O/heating.
Sorry for the fu(k up.
Hope you didn't adjust to suit.

Not gonna do anything til after work, but thanks for the advice

[Chriss]

I ride a Triumph Daytona 600, and I run 32 front and 34 rear. My dealer set my tyres to 42 front, and 44 rear (was bloody scarey). Hope that might be of some help.

You can usually tell if they are too low because the bike will often feel slithery and uncertain. It is more pronounced on a slimey/ wet road.

Hi

G can probably say more (more experience playing with the pressures), but a higher tyre pressure will result in a more skittish feel. Lower pressures will result in more movement in the tyre and feeling less stable. On the front a tendency to try and turn in as you are cornering.

All the best

Just a case of finding the right balance then I guess!

[Wave2k]

having a low tyre pressure dramatically changes the handling of the bike
i didnt check mine for ages
i had 15 PSI in the front and 25 in the rear
pumped them both up and it handled like a dream

I was running my R1 by the book, 36 front and 42 rear as it still has factory Dunlops on, and then someone advised me that I should be running them slightly lower and pointed me in the direction of Dunlop Tyres' UK web site which has a fitment/pressure guide and advises to run 36 front and 36 rear solo psi.
