Re: odd tyres?
 

Looks like it squared off, i.e the middles worn but the edges are OK.

Is it on the wear indicator in the middle section of the tyre ?

At the end of the day its your bike, if you are'nt happy with the tyre then change it.

A quick google reveals

The grooves of the tread pattern must have a depth of a least 1 mm throughout a continuous band measuring at least three-quarters of the breadth of the tread and round the entire outer circumference of the tyre,

OR

if the grooves of the original tread pattern of the tyre do not extend beyond three-quarters of the breadth of the tread (i.e. common with motorcycle tyres) any groove of the original pattern must have a minimum depth of at least 1 mm.

At the end of the day its your bike, remember a squared of tyre makes the bike handle in a very strange way. Mines very square on the rear tyre and it tracks horribly over white lines etc etc.
