Track tyre pressures

[forkoil]

As a bornagain, the conventional wisdom of late 70's racing was to run 40+ psi in the tyres of the day (like pirelli phantoms) as opposed to street 30+. With modern tyres, is it still the same or do you just stick to recommended street pressures?

[Cajun]

lower the pressures for track riding

But like anything alot of is personal prefence,

Go with your street pressure, and slowly drop slowly them until you get to a pressure you feel comfotable with

[Ralph]

One of the most common questions and everyone has different ideas, I'm no different but here are some things I've learn't.

For track use a good starting pressure for sport oriented radial tyres is:
Rear 33/34 psi Front 31/32

The best thing is to experiment with what you fell comfortable using.

For track days a good "rule of thumb" is to get a 10-12% rise in pressure between
cold and hot. If you are getting more of a rise then this it would tend to indicate
that the tyre is getting to hot. Less and the tyre would not be reaching
optimum operating temperature.
Check your pressures as soon as you can after you leave the track, and see
if you are getting the 10-12% rise mentioned above. If not, try adjusting the
pressure and check again after your next session.

Hope this helps.

Pressures are very much tyre brand specif ic

depends on bike tyre make type of track type of weather but i cant be stuffed doing all of that so i just run 30 front and 32 rear or 30/30 i guess that if the tyre doesnt ball up its too high but if it balls up too much then its too low

Additional to the ball up / or not balling up "look" , if on the track, one needs to consider machine turn in response, stability, cold shear & the whole relationship between shock & tyres that goes on & has a large effect on things. Its a pretty big subject overall when it comes to track applications. For the road its more to do with the load on the bike one up or two up, riding style & personal preference for wet weather performance over dry weather grip & lifetime of tyre expectations.

exactly!!!!!


I reckon...talk to guys who are racing and using your tyres...and possibly a similar setup..and ask questions to...plenty of questions!!!

Here's my ultra secret setup for tyres.....
Buy a real expensive pressure gauge, not digital as they aren't as accurate, fit tyres on at work and set to 30psi with the dodgy gauge on the machine, take 'em home and put 'em on the bike. Leave it for a week or so then chuck it on the trailer and go to the track. Look to make sure they aren't flat. Ride around track & lend expensive gauge to fellow bikers, load up, go home. Repeat if tyres worn out or just repeat from step 3.

i dont get it

[codgyoleracer]

I tried that once Death.........It hurt

I hear lots of weird ideas on tyres/pressures and how heat affects them and many are wrong. Make sure you get advice from people who know. I've only been ridin 40 odd years and I'm still learning ! Gaz.
