That usually does the trick.

What no Stout??????

Is that on a standard road bike?

That explains how you got the holes in your rear hugger

As Zathos suggested scrubbing in tyres is a bit like running in an engine. Very little need to do much of either with a modern bike and I would suggest by the time you get to the end of Holland Street job done, then you can stop off for a pie or three.

Good stuff, but now yellow has changed his bike I Isn't got anywhere to keep the pies warm :I can't believe it's not butter! :I can't believe it's not butter!

On the road , no difference , the "guidelines" for scrubbing in tyres by manufacturers are just to cover their erses if you bin it

What did I write...MANUFACTURERS SUGGEST..so not bollocks, it's actually a fact.

I know what you are saying, but think about a race tyre and a road tyre. The race tyre gets binned at the end of the day, so what if it has not bedded in on the rim properly, no long term damage, unless you fell off . Aye, your'e right, it is all to do with covering there arses, but surely it is better to over cautious than under cautious??

i am pretty sure that I am not the only one who has had new tyres fitted and after doing a couple of hundred miles, had to bump up the pressure in them...and then not had to touch them for months..or is it just me?

Last I heard he was trying to fit the exhaust from his old bike, so if you can catch him ............. :I can't believe it's not butter!

Now there's an incentive

For Bazza , Gayness , which I believe you drink is stout The new bike has a very similar Termi exhaust so you still have somewhere to dream about keeping pipes warm , to go with your stout :I can't believe it's not butter!


For Backs , road tyre , race tyre , proddie bikes use road tyres , same things you can buy from Auntie Bev like Dale says , the warm up lap is enough to scrub a front in and then race on it , if they haven't bedded on the rim properly they won't even inflate so I think that might be more tyre lawyer arse covering speak

Throwing them away after a race isn't what happens , many people buy part worn ex-race tyres to fit on their road bikes , they are still good for quite a few miles and a real bargain , does a pair of supercorsa's or D207GP's that have done 20 laps of knockhill to fit your 600 for £80 plus a tenner to get them fitted at Rob Sillets sound like a good deal ? :I can't believe it's not butter!

Of course it is tyre lawyer talk, but I would rather take it easy for a bit than risk falling off, no matter how small :)

Sorry but you cannot totally negate the risk of falling off

And should anyone want tyres such as these, give me a shout.

Zathos...by leaving the bike at home and taking the car, I negate falling off!

Come to think of it, i have never scrubbed in a car tyre..and never fallen off one of them :)

I bet you have never driven slowly for a hundred miles with new car tyres in case the bead hasn't sealed either

That is very true and the only way to negate risks associated with motorbikes. I.E. don't use them.

If you engage in the activity you accept a certain amount of risk, the level of risk can be managed but never completely removed.

Can you tell I'm writing a conference paper on risk management at the moment :I can't believe it's not butter! :I can't believe it's not butter!

What if you are knocked down by one ?

What about the risks of buying a greasy pie from a road side van then????

That's where the management comes in.....I only have four at any sitting :I can't believe it's not butter!

Big Kneed Al (master of the emergency stop & "stand up" comedian), can I suggest you open another message section for threads like this one, absolutely priceless, on second thoughts maybe we should just move it into the Jokes section.

which is the funny bit then ?

From the June edition of Bike magazine (Really Useful Section):

Why do I need to scrub my tyres in - and whats the best way to do it?

You have to scrub in tyres because they don't grip properly until you have. There are two reasons for this. Some manufacturers use things called release compounds to stop the tyre adhering to the mould. Other manufacturers don't use them, but use processes of curing/moulding a tyre that bring certain slippery substances to the surface and these need to be evaporated and scrubbed off before maximum grip is achieved.

The second reason has to do with the tyres actual surface. A tyre will grip more readily when its surface has been roughed up (on a small scale) because there's more grip between two rough surfaces than two smooth ones.

The best way to scrub tyres in is carefully - most manufacturers recommend taking it very easy for at least the first 50 miles. However, you can scrub tyres in with less than two miles on a track. The trick is being gentle. Don't tip in, brake or accelerate very hard until they're warm and take the first few bends easy, increasing lean angles with each corner to gradually work the whole surface.
