Scrubbing in new tyres?
 

so as the title says i have my new tyre on but they said i need to wear it in for 100 miles, the roads are cold and icy by me and im scared haha could i just sand the top layer off or do i really need to ride it in?

Just ride. But don't try to scrape the pegs round the local bends for a bit. I've ridden home from having a pair of fresh tyres fitted in torrential rain in winter and been fine. Just be aware that until they're scrubbed in they won't be at their best.

Definitely wouldn't sand it down mate, like jambo said, just take it easy for a while

He's right, just go round corners slow, forget about everybody else. upright you won't notice a thing

cheers guys, what about when i do need to corner a bit lower down? or should i wait for it to dry and warm up?

The tyres do not have a coating of explosives or banana skin on them, just ride normally, and build up the lean over the miles. As you build the lean up you'll gradually scrub them in, and they'll be fine.

Or to put it another way, these are new, just get to know them for a bit before trying anything heroic and everything should act as you'd expect.

Scrubbing in-o-phobia! I hate that they even tell you to scrub them in. Makes you paranoid they're coated in grease! :) It has to be a load of tosh in my opinion, cos any one portion of the tyre will not be scrubbed in until you use it. The portions used at high lean are never gonna be scrubbed in until you lean the bike over at speed and actually use them. Yeah, they might get some slight weathering/dirt in a few hundred miles, but the surface won't be 'scrubbed'.

I believe (or so I've been told) that tyres used to have factory grime or protectant or something on them. Also in the showroom new bikes might have their tyres polished (bloody fools!), but I've never had any residue on new tyres. The only thing I can see you doing to give the tyres a chance is no throttle or brake at lean, so you can hit that portion of the tyre with minimal forces exerting on it. Aside from that I think the whole scrubbing in thing is somewhat scaremonger-ish. What Jambo said about getting to know the tyres makes far more sense to me.

cheers fallout but yes it definately is scrubbing in-o-phobia

It's not complete cobblers, more than one person has ended up on their back side within sight of a tyre fitter. But I think it gets over stressed and over stated in some people's minds.

Tyres used to use a release compound to make sure they came out of the mold cleanly, which would leave a sheen on the surface. I'm not sure this happens anymore at all, some manufacturers have confirmed they don't and I'd expect the others have followed suit.

Part of a tyre's grip does come from the surface being rough, which it isn't out of the mold. And if you add lean gradually most of the contact patch will be rough, with only a little of the fresh rubber introduced at a time and roughed up. If you go from 90 to 45 degrees of lean on corner one, then 100% of your surface is smooth, which would probably have an effect on available grip.

The getting to know the tyre argument also comes in. If you're used to riding squared off, worn out tyres, it can be a surprise how fast the bike drops into corners now that the profile is something like right.

For all these reasons it's a good shout to take it easy for a little bit, but they don't go from greasy to safe as you tick over the 100th mile, and riding bolt upright won't ease the edges in either.
