Anyone have a good method.
I decided to just go for a plod around and then ended up doing circles around a car park until I realized that every bay had an oil patch/stain.

I am only on 15 miles atm, and have about an inch on either side to scrub.
 
I had a new front tyre fitted yesterday, I just when for a ride
no hard braking n leaning to far over at the start.
it doesn't take long and most fronts will always have a little left on the sides.
 
just take it easy is the best advice for the first few hundred miles

if you lean it too far you'll feel it start to slip and you can pull the bike upright
 
I just go out for a long ride to scrub em in, I certainly don't bother doing circles in car parks. :p
 
Long ride should do it. After a while I also swirv left to right at low speed on quite roads to scrub a little further, kinda like a MotoGP warm up lap.
 
There's no science to running in new tyres, the important thing to note is you're not trying to remove the shiny surface but you need to do some miles to work the preservative out that the manufacturers put into the rubber while its on the shelf.

They usually recommend 100 miles but that's on the safe side. To give you an idea I put a new set of tyres on my track day, I did 3 sighting laps followed by a slow 5 lap session. After that I was happily pushing the bike at a pace I was comfortable with which is far higher than the road. The circuit is about 2.9 miles long so after about 23 miles of use they were fine, but I suggest doing a bit more on the road :)
 
I pick my new bike up on 1st October so both tyres will be new and I've never had both tyres new at the same time before so once I get home and put on a few accessories I've bought, I'm going to go scrub them in. A nice little route I ride, around 50 miles, will be done and if I feel I need to, I'll do it in reverse so they're scrubbed in that day.
 
Bump front wheel up against a mates rear wheel. Get him to do a burnout while I lean the bike side to side. Scrubbed in within 5 mins.*

*I don't actually do this
 
I honestly considered a belt sander...not removing rubber just making the wheel spin on the abrasive belt, 5 mins of that would do the trick.
I'm not really sure I need to scrub in anyway as you have to take it easy for the first 100 miles - I take it easy almost always.
 
its also the heat cycles in the tyre,warming up/cooling down that helps it burn off the release agent from manufacture

just ride it normally but carefully on turning that's all you need to do for first few hundred miles
 
I wondered how the chicken strips ever get anything but 100% load. You think the heat from a mostly upright ride will burn the heat agent off even on the outer edges? I suppose that makes sense or you would never be able to do a proper lean.
 
I just got new tyres put on today. Took it very easy on my ride back from the dealer. Think a couple more rides out and everything will be fine. On the service report that I got after the service it said to take it easy for 50 miles to bed them in.
 
Light the touch paper on a new rear and your end up on ya arse last one I see leaving local dealer was a gold wing dealer reminds customers 2 to 3 times be for they leave.
 
I am now 90 miles in and not even wore off the nipples yet.
The tyre seems to be ok though and is already a good way grippier than the last one.
I always go the long way home which means I take on one twisty road (2 long rights and a couple of medium lefts) instead of no bends at all.
I keep looking for a good couple of left handers to balance out the roundabouts but theyre few and far between around here....perhaps I need to get out more
 
Yea, just ride normally, you don't actually have to touch the surface of the tyre to tarmac to scrub the edges in. It goes naturally. Obviously you'll have to do a few miles (30 or so) before it's fully clear. But I normally take it easy for the first 5 miles and then ride as normal.

Which is normally suicidal.
 
In the dry/warm weather...

up to 5 miles, ride sedately.
5-20 miles start pushing closer and closer to the edge, cornering on low revs.
20-30 miles start cornering harder at speed.
30+ do as you please but keep an eye on it.

In the wet/ cold weather... double the miles.
 
You can scrub in a tyre in a mile long warm up for a race so its not really a massive job. Granted I use warmers before that and then a slow but progressive amount of more lean and push on it but its usually golden to go within a 2 laps :)
 
Dont worry about it is number 1 rule.

Just be extra hard on the brakes with the bike upright and it will be sorted after 5-8 miles.

The slippery evil mould release is not used in tyre production anymore.
