New Tyres - By Ren Withnell

"When you have a new tyre fitted onto your motorcycle, take it easy for the first 50 miles."

This advice is as old as the hills and the source of myth and legend in motorcycling.  But it is worth repeating.  Rubber is sticky stuff.  It needs to be to keep you and your bike sunny side up.  Unfortunately for the manufacturers of tyres sticky rubber sticks to their moulding machines that make your shiny new tyres.  To stop this the manufacturers have to use slippery stuff in the moulds so they can get the tyre out of the mould.  And this slippery stuff is all over your shiny new tyre.

So here is Mr Keen, at the tyre shop having a splendid new piece of rubber fitted to his Kawukihonaha GCYZXRRRRRRR.  He pays his £150 and sets off like a rocket.  At the first bend the new tyre slides gracefully from under the bike causing many thousands of pounds damage to the bike and hurting Mr Keen.  Mr Keen is not so keen on this new tyre.  

If he had ridden the motorcycle carefully and gently for the first 50 miles, the slippery compound on the tyre would have worn away leaving a super sticky piece of rubber in contact with the road.

One thing that is commonly overlooked when "scrubbing in" a new tyre is to be careful of the edges.  If a new tyre is ridden for 50 miles on a straight road then the centre will be clear, but the edges of the tyre still slippery.  And you cannot "carefully" go straight to the edge of the tyres.  Increase the angle the bike leans through corners gradually.  

Have Fun!
