    I hope I haven't missed it cuz I have searched here.... and Pirelli's US site was no help either.

    I currently am running a pair of Pirelli Scorpion S/Ts on my '92 BMW GS PD, and the front's getting a bit bald. It's a 90/90-21 54H. SW Moto Tire is only listing the Scorpion A/T now, so first off, what's the difference between S/T and A/T, and is it OK to mix and match? Seems I recall when these first came out that the S/T was more street oriented, but now they look the same so am guessing it's just the speed rating - which is not a factor on this bike... Secondly, I'm wondering how to tell if a tire is tubeless or not from the listing. They list PIRELLI MT90AT 80/90S21 TT FRONT and PIRELLI MT90AT 90/90-21 54S. Does TT mean tube tire? The second one doesn't say anything that indicates to me that it's tubeless...

    And what's up with the new Scorpion Trail? Looks like much more of a road tire than these others...

    Thanks man! I knew this had to be on here somewhere, but searches didn't turn it up. This is excellent - thanks for compiling all that info!
