My first priority with bike tyres is always to get fresh stock. When I got my GS500 i immediately put the freshest stock I could find. Tyre guys had 4 to 5 year old Golden Boys, Dunlops and other brands. But I asked them to get me fresh ones. In the end I got Vee Rubber tyres, one was oct 2011 and other nov 2012. The old tyres, I just gave them away.
With local tyres there is no manufacturing date written on them. So I always buy from a place where sale is high, as they will be having more chance to have fresh stock compared with gali mohala wala shops. I never run more than 2 years with local tyres in my cg125 or gs150 and change them regardless of their condition (usually give away for free).
Dear fellow bikers, do not compromise on tyres, they are the only contact between you an the road. The whole ride is affected by the quality of tyres. I believe that we neglect this important part of our bike the most. No offence to PBC, but their president Zahid Malik installed used trail tyre (front one) on his gs150 (which he trailed up last year). That tyre was not fit for the road or even off road. It was quite old. It was a big compromise on safety on not only Zahid's bike but also for other on the road (as a crashed/slipped bike can hit other vehicles on the road).
I think tyre quality is as essential to safety of a biker as helmet, side mirror and working lights (front, back, indicators). Here in Pakistan bikers ignore this important part which can result in fatal accidents. May Allah keep us all safe. Amen.
