Not a fair comparison IMO.Another down vote for Avon. Never had them on a bike but have watched chunks come out of their automotive "performance" tires at road course track days...
Good enough reason for me to avoid them. For the bikes I think Michelin or Metzler are the way to go. They consistently seem to rack up miles with excellent wet/dry handling and I hardly ever see people complain about them. Put a set of Metzler on our Dyna this year and could not have been happier. Will probably change our Sportster over to Michelin this winter to give those a whirl...or maybe some Night Dragon's. Metzler is manufactured by Pirelli BTW so I'll guess they are similar in quality. Tho, I'm sure the compound in the ND's will have less tread life.Not a fair comparison IMO.
Having said that. Have had good experience with Avons on my bikes. Stick well in all conditions. But are a softer compound then most. Mileage per tire is not their strong suit.
Other brands get good reviews here for both traction and mileage.
