I dont believe the 404 is rated for the Valkyrie.........
I'm on my 2nd D404F 150/17B/80 Got 20k off my 1st one, was not to the wear bars, my 2nd has 8k, showing very little wear, also use an american elite 165/16B/16 on the rear, looks good at 8k, I like to change both at the same time, has 1015 lb load rating, almost 100 more than an E3. I like them. 100 bux for the front, 155 for the rear at Jake wilson.
