I've been searching for tires for my '69 Victor Special. As you all know that task has many complications... The only available tires that I could find that would be made by the same manufacturer, both bias ply and in the correct sizes (3.25x19, 4.00x18) are the K70's. I'm not totally enamored with the K70's on my A65 and I would like more aggressive tread for the Victor.
The I ran across a website last night, new to me, Edge Exreme Sports
They have both of those sizes made by Duro in an endure/trial type tread. More unbelievable is the prices, I ordered both tires with the free priority shipping for under $90! It just seems to good to be true, I'll report back once (if) they arrive and they are not from 1982, or for model bikes, or made of marzipan, or....
