ok guys let me explain tyres a bit to u all.
our only consideration these days is softness which is driven by the shop keepers (similar to the one that is body condition driven by dealers while buying a car).
there is more to the tyres that we use on our rides. firstly complete car engineering is at one side and the performance of the rubber underneath has equal priority considering its the only contacting point with road.
every company make different types of tyres and they do continues research to improve them.
every company make soft tyres and hard tyres (purposely) and their are relevant ratings associated to it.
traction ratings dictate if the tyres is going to provide good road grip or not. its written on the side wall of the tyre. its better to prefer an A rated traction tyre. personally i am using a AA rated tyre now. usually A rated tyres are a bit harder.
than there is temperature rating it should be A (written on the side wall of the tyre) for pakistani weather preferably.
than there is treadwear rating which tells if tyre is going to wear more or less. i believe smaller the tread wear number means longer the tyre life.
now coming to yokohama, michelin, dunlop or bridgestone?? i would suggest evaluate the ratings first. also directional tyres usually have better wet grip because their tread is designed to disperse water at a faster rate.
as per my experience currently best combination of orignality, comfort, road grip (both wet and dry), price and look is provided by Yokohama blue earth A.
i personally installed yokohama A drive R1 ZR rated tyre in my car considering i prefer a bit harder tyre since it provides better road feed back and improves the ride feel but thats just me.
also as far as i remember there isnt any rating on the euro stars and their asymetric pattern might not be very suited to continues wet conditions however since there is not so much rain in PK usually so they work.
