Been looking at tyres this evening and it looks like that the major online tyre retailers in the US are no longer stocking the Azaro AV46. One site had a close-out sale on the tyre but all stock was sold and NLA.
Can't find anything on the Avon site about it except they no longer list the tyre.

 

Sheeeet.

Glad I picked up a rear wheel from a K11RS so. 

Yes they have been discontinued for a few years now, it's just been old stock through the dealer network that had been available. I ordered a few extras last year.
I think Pro Accessories in Australia still have a few.

In US, there are not many also, I was looking also last week, some are still available in ebay and amazon.com, but they jacked up the price, most big tire stores are out of stock.
