Hey thank you for the reply. I would be replacing all 4 tires since I have no interest in wasting money replacing the punctured tired with the same lame tire. I've only got 4,500 miles on them! If this didn't happen, I'd normally just ride them until about 20k miles and then change out all 4. I despise subpar tires that compromise safety and piece of mind. The ecopias do say made in Japan on them though which In thought was rare to see and initially led me to believe they were good tires.Not sure about Yokohama or Continental, but Bridgestone Dueler Alanza Plus was one of my top two choices. Given the consistent less than satisfactory reviews of Ecopias (on this forum and Tirerack.com), I'd rather replace all four and get new set. And I do not even know why Costco carries Bridgestone Ecopias given they are not the most loved tires and has consistent bad reviews.
Not sure how many miles you have on those tires, but if you replaced only two, you re looking at constantly having mix and match tires for the rest of the time you own the car because you'd now end up replacing only two most worn tires every time-going forward.
@Tinjimnj. I'm interested in the other brands because they are the newest gen tires with seemingly good reviews at a little lower cost that are supposed to rival Michelin and last longer and be quieter while giving excellent 4 season traction, especially in colder weather with light snow. The Continental LX25's get raving reviews but not available in this size. The Michelin Defender LTX M+S are top rated but very expensive.
