Tyres - avoiding the square off?

[b1k3rdude]

• - will it fail an MOT on squared off tyres?
  
• - the squaring off is presumably a result of the dual compounds in the tyre - are these the norm now or can you buy uniform compound tyres?
  
• - can anyone recommend a good replacement tyre for my riding style - 95% commuting 10 miles each way, the odd fun weekend jaunt - no scratching / track days etc. - around 4000 miles/year.
  

• No, but if there are properly squared off you will get an advisory.
  
• BT's are famous for this kind of bollox. Yes continental road attack's or Conti motions are good.
  
• see above, I have Conti motions on the FZS1000 atm as at the time they were cheap, conti are getting to big for thier boots as the RA's have shot up in price..
