Breaking in new Avon slicks?

Hi Chaps

Just after some advice from you guys on breaking in new Avon slicks on a single seater.

We chucked a set on this afternoon at Curborough and they were pretty poor to be honest.

I'm hoping after a few runs they will start to come good.

One run normally enough. Nothing special required.

What compound ?

As Ash says, don't totally trust them the first run unless they have come direct from the factory. 2nd run they should be fine.

Ah well the first run they only managed about 3 corners of Curborough due to a stuck throttle so probably not enough to count as a run.

Cheers guys hopefully they'll be good at Prescott next time out then

92 front and 15 rears

Was the fronts that didn't feel as good as I expected.

I don't think you will notice that much difference in grip from the 15s, yes softer but on Jedi I just chewed them to bits on sprints. Great for the hills

Hi Simon

I wasn't expecting a big difference front to rear, it was more the overall performance from the new set.
They felt worse than the old set I'd just taken off

In my LTD experience on brand new slicks, the first few corners do need some care on fresh rubber.

It used to be conventional wisdom (maybe it still is ?) to run softer on the front, as the rears could be spun to warm/clean them before a run. Nowadays, with wheel-spinning banned from many venues, is it still the right way to go ?

Crossplies or Radials? Unsure if that makes a difference but...

I've had some huge variation between crossply tyres bought over the last few years (same retail outlet). Some A15's have had far more grip than others, some have been far more durable than others, some a combination of the two. Some have split down the moulding line after one lap of a short course, some have shown no sign of that after many laps of a long (e.g. Combe) circuit.
I don't use anything else except A15's or Circuit tyres (Jedi), but then I don't frequent hills. Shortest thing was Kames, and that would destroy A15's at the front.

Tyre warming (aka spinning the wheels, making lots of noise, and spraying gravel everywhere) has fortunately been verboten at most circuits (except Croft so far this year). Hoping it'll stop it there as well.
