i am on Precedas too, since Nov'04 (41k kms then & now 52k kms) .... Thailand made. If you want Japan stuff, they can order.
Quiet & softer ride was my first impression ... well, comparing to older tyre which was the Dunlop SP2000 from Germany. At 41k kms it already have a lot of blisters & very noisy ...that prompted me to change.
Only problem i have with these Precedas is that i seem to have to go to top up the tyre pressure more often, like every 1 or 2 weeks ....ALBundy, similar experience?
