Likely true.
As I said, I don't mean to be a scare-monger. However, I replaced a worn-out 25mm tire with a brand new 23mm and felt noticeably worsened traction in the next criterium race I did, and went back to a new 25 up front and it was pretty much back to original. It may well have been due to slightly different tire fabrication, just thought I'd throw it out there. Nobody's had a similar experience?
