much depend on your driving style. the older ze-912 is okay but a little on the soft compound, thus, not suitable
on rough road surface. the newer thailand made is okay for normal driving.
of the list, its down to xm2 and c.drive2.

if you don't drive aggressively, stay with ps3. its a good all round tires which is more than compensating the
sidewall's shortcoming.

pump your ps3 at about 30kpa higher than manufacturer recommended may help. else, re-002, ku-36, federal 595, r1r, ad-08 and the list goes on...

comfort wise, ps3 is a rung above the pp2 but pp2 beat the ps3 in handling.
i concluded the grip and traction are on par as my previous experience with ps3 return a good wet grip.

ps3 and ze-912 are decent, if they had it in 195/50/15.
