Mitas E-07 is this normal

[kwakker]

I fitted this tyre about 4 months ago and see there is a crack next to about all the knobs running down the middle of the tyre-

What am i to do?
Is this dangerous or not as I comute about 120km a day?

___Now i hear that you have to warm up the tyre before you go out on the road -- f1 here i come.
