Not sure about the milage , but I put a set of Avon Venoms on My Sport and the ride improved alot ! I run 38-40lbs rear and 36-34lbs front . On a Interstate where road work had started on 1 lane other bikes were having issues , not with the Avons . I ride with more confidence with them and that beats milage for Me anyway . Might try the Metzlers as friends have had the same good results as posted here. .Ride Safe...WVleo
