I'm surprised Bridgestone lets Nissan install inferior versions of tires. My confusion is an example of how this can hurt their reputation.
I was kind of thinking this also, but in the end if people end up needing to replace their tires much sooner, Bridgestone will end up selling more tires. Sure some people might purposely avoid them because the OEMs had such a short life but many others will probably just replace the tires with the same as OEM and not really think about it. Still others like me or people on this forum will read and find out the OEMs were built specifically to be cheap and the aftermarket equivalents are much better, so they'll still go with the Ecopia's(albeit the +'s). Bridgestone and especially Costco do make the Ecopia +'s very price competitive and while maybe if someone were giving me the tires or they would have been the same price as the comparable Michelin's I'd have gotten the Michelin's but in the end I ended up with the Ecopia's and have been happy.
Oh and it's not just Bridgestone that does the cheapo OEM tire game, I've had new vehicles with Michelin tires that wore out before 40k and the Michelin's I installed after that got 80k+. Just another example of cost cutting measures that get implemented when selling a $30-40k vehicle
