'Scrubbing' New Tyres :)
Steve P
shiny new BT45 fitted by Central Wheels in Coleshill (Daz, cheers for
the recommendation). Anyway washing bike down after 'quick' run on
Sunday under the guise of helping Dad shift some stuff [1]. On the way
down the garden SO pipes up:
'Are you going to scrub your new tyre?'. I then had to explain what
'scrubbing' in really means [2] whilst trying not too laugh!
[1] How can a 10 mile round trip actually cover 60 miles?
[2] How do you scrub the outside of the tyre if you are meant to be
taking it easy? :)

I have two methods.
[1] Ever tightening figures of eight in a car park
[2] A clean deserted roundabout at an industrial park.
I mean three methods.
[3] Virgin kneesliders that need scrubbing in.

It's easier to do figures of eight shirley.

Best approach is to put your bike onto the pitstands.
Fit tyre warmers for about an hour.
half a lap on you favourite track, and you should be ok......
Seriously, just go easy for a few miles, and be extra careful if it's wet.
If the conditions is dry, and not to cold, you just find a bit of curvy
road, and gradually increase your lean angle.
you don't want to be in a situation, where you suddenly need your tire all
the way to the edge, just to find that you did not use that part of the tyre
before. (But then again, if you never used that part of the tyre, chanses
are that you never will anyway...:-))
If it's wet, the wax on the tyres may be slippery as hell. Actually a bit
funny as well.
Getting out on the road in the wet after fitting a new rear, just nice and
easy, and then gas it. you'll get about two powerslides untill the wax on
the center is gone :-)

Dangerous game to play, that one ...
All the tyre bods I've spoken to say that artificially scrubbing tyres
can be lethal; causes stresses within the carcass itself and,
particularly if sandpaper is used [1], can tear up the tyre internally
to the point where it looks fine, but can fail catastrophically.
[1] the little bits of grit apparently get into the rubber and work
their way through the tyre, doing damage as they go

He's playing a very dangerous game for himself and possibly others. I've
seen this type before, they go tearing along a straight then brake hard for
a bend and lose it.
Scrubbing tyres in is more than just rubbing the surface, it's bedding in
the seal, settling in the banding, squeezing out the release agent used in
the manufacturing process, etc.

My prefered 'method' for scrubbing in new tyres is to simply weave -
as if through invisible cones - like racers do to warm their tyres up.
Start with a gentle weave and progress to a wider weave (therefore
increasing the angle of lean gradually). To be honest I do this at the
start of most trips anyway - regardless of the newness of the tyres.
Just don't use the front brake - don't grip the bars too hard - keep
your upper body relaxed - and modulate the throttle gently (accelerate
through each lean 'phase' and roll-off slightly before initiating next
lean phase). It's good counter-steering practice too!

"You see, Paul; scrubbing in a tyre is very much like making love to a
beautiful woman. You can't just rub the surface; you've got to bed your
seal in, let your banding settle, throw the thing from side to side with
abandon, letting yourself go down as far as possible and then finally
squeeze out your release agent ..."

Yep - and takes a couple of laps for a race bike - don't forget chaps...
