Yes---Japan Helix (Fusion there) tire lost tread---did not go down---at end of high speed freeway run---remember, tires OEM on Helix rear J rated--62mph on bike that would go 70mph plus downhill/tail wind and number #2---US new Honda ReFlex rear tread came loose---stopped before more trouble.---Both times Bridgestone--- In US, Bridgestone replaced tire. On Helix (had 4 new ones) questioned Honda on putting 62mph tire on bike that would go faster than that---really no answer that made sense- Helix, Japan version felt faster than US models.
Further Guzzi V-7, Pirelli tires--Minneapolis, rush hour, S curve--spike in rear tire---high speed, ended up in field, no damage to me or bike. Tire junk.
Something to remember, outer tire crscked inner carcass the holds air way still be ok. My take---fresh tires may allow you to live longer!
