Michelin Power Competition Tyre

RoadRacer1973

Hi All,
I bought a Michelin power competition tyre from Chain Reaction and today i received it in the post.
I'm fairly new to road cycling and as i opened the box i noticed this tyre looked fairly dirty with a hole in it.
After looking on box the hole on the tyre is next to initials TWI.
On the box it says "These tyres have a layer of protection that will disappear after the first few kilometers "

I payed over £30 for this tyre and i don't have another too compare so my queston is is this hole a fault or is it their for a reason and will fade away when the protection has disappeared?
Any advice would be grateful.

As you look you will see the hole is this a fault and needs to go back or is it normal?

The hole is just above the w on the word power

The "hole" is the wear marker, as for the muck again perfectly normal mine were filthy its just transit muck I wouldnt worry over.
The wear marker is a similar idea to a car tyre once thats flush your at lower rubber layers so worth looking at new ones.

TWI means tread wear indicator. The hole is there to tell you when you need to replace the tyre; once the hole disappears then the tyre is worn out.

As for it looking a bit dirty, I wouldn't worry. The rubber on tyres is pretty tacky so will tend to pick up dirt. Just give it a wipe with a damp cloth once you've got it fitted.

TWI stands for tread wear indicator...
