Yup, acutely aware of the difference. SWmototires makes it easy by clearly labeling them as ST1300 OEM "F". I think the BT021 has pretty much replaced the generic BT020 "U" models now anyway. Bridgestone apparently intends to continue manufacturing the BT020 for OEM fitments instead of developing a new BT021 OEM version.I've had the best luck with the OEM 'Stones. If you go this route, make absolutely sure that you get the OEM "F" designation tire on the rear. The generic "U" tire is a POS.
That may be your experience but I doubt there is any meaningful difference in Avon's rubber compounds or construction that contributes to your flats.I forgot to mention the Avons. These are probably my favorites from a handling, grip and wear point of view 12K rear and at least 15K from the front I predict. The thing with the Avons is that I've come to believe they are overly susceptible to punctures. I hadn't had any flat tires in probably 20 years until I started using the Avons. This goes for both the Storms and the previous generation Azaros. Every flat I've had in recent years has been with the Avons fitted. No flats with Bridgestone, Michelin, Dunlop or Metzelers.
You do demonstrate why the debate will rage forever. The subjectivity of tire selection is one of the constants in the ST1300 ownership experience.I may be the odd man out, but I like the OEM Dunlop Sportmax, as a predictable all weather tire.
Well, I put the Metzler Z6's on and the jury is still out.
I find that they have lots of grip but I don't ride that hard. For touring I find they are not as stable as the Bstone's and they feel looser (great for a bike you want to fling around, but a bit disconcerting on a NA sporttourer). They also seem a little less stable at +160 km than the OEM's.
They feel like they have less material making contact with the road at any one time.
