"Scrubbing in" new tyres?

This what you mean?

Of course not. That is a cbr. He rides a proper VFR!

are you running a race slick? or sport/road tires? tire warmers or not?

tire warmers on race slicks, just go hard from lap 2. street tires will take a bit longer, but track surfaces are abrasive and will scrub a tire in pretty quick, go should be scrubbed in after the sighting lap and 2 laps into the race. only way to know for sure is to push the bike til you feel the tires sliding. You should be sweet to be knee down pretty quickly though.

Sent from my HTC Desire 310 using Forum Fiend v1.3.2.

Will be a set of road tyres (Sport Demons) without warmers.

Hopefully will be alright will just work my way into it. It was the knee down part that I was mostly concerned about, that far down on the tyre n with that slippery shit on it might not be fun. Will just ease my way into it. Just gotta convince the wife to let me buy a new pair first! The ones on it are 8 years old and were used on the road by the previous owner so were a bit squared off, seem to be getting better now that I've done a few track attacks on em though, but not as good as other Demons I've used on the track I think with other bikes.

do a skid au.

As a Hamiltonian born and bred, doing mean skudz iz in my blood!

Nah fuckit, you'll be sweet. Like this guy.

8 year old tyres!!! Jesus fucked on a wooden cross don't ride on those pieces of shit man. Show your misses this post, they are rooted and will fail you painfully.

Your going to take yourself out and even worse someone else with you. Don't ride on them please.

I have had my mechanic check em over (road racer himself for many such years) and he reckons they are alright but to change em when I get the chance. I think this post has made up my mind though, cycletreads.co.nz it is :-)

With age the rubber hardens and effectively 'goes off' in the grip department.

Even a non scientific thumb nail test by placing your old tyre next to it's new equivalent will display the difference in hardness when you try to press your thumb nail into the rubber.

Cars are affected the same but it is significantly less noticeable due to obviously having four wheels and inherently more stable just rolling along. BUT apply water to the road and the old skins are sub-par in grip and stopping distances.

Is a good idea. Little bit of damp and your off when the compound is old. Even in the dry pushing beyond road angles your running a risk.
Trust me I was good at crashing even with new rubber.

Or a bit of oil as happened to me last month :'(

Cheers guys. Some new Sport Demons should be fitted soon. Was trying to track down some BT-39s but the bastards went out of production in VFR sizes last year. POOS!
