IIRC, the Scorcher 31 is belted and the latest Scorcher 11 is radial. Don't quote me on this one though  .

I was told by the HD dealer that the Michelin Scorcher 31 is the same tire as the Commander. Michelob just changed the name.
Did I say Michelob? I am having a Golden Draft Light now. ha

I have Avon Azaro tires

Bought them knowing that grip, not mileage, is my number one priority for tires (on my bikes and my Miata)

I'm very happy with them

Only you know your priorities, every tire is a compromise, just pick your criteria and ride within the limits that imposes

+1.  I would rather have the grip and pay for tires more often.  I have a Vstar cruiser and the tires are one of my biggest complaint.  No tire that fits it feels sticky enough to me to feel comfortable riding aggresively at all.  Makes for a boring ride most of the time.  I even looked for ST tires that would fit it and it wasn't happening.  SO I too will take the grip over mileaage.

Had an AV46 rear in the stock size delivered today for 130.99 including shipping from Rocky Mountain ATV/MC. Got it in three days.

+1 on Rocky Mountain ATV/MC. They had the best price, delivery, and customer service.

I found a Mich Commander on eBay for $100 yesterday. I bought it. It was too good of a deal to pass on. So now I have 2 new rears, supposedly the same tire (Scorcher and Commander).
I'll be able to put them side by side and see how they line up when the Commander comes in the mail.
