Just bought a new set of Avon Roadrunners (NOT road Riders). The runners are still the universal type - either front or rear. Doesn't appear to be any change in them re ply alignment, etc - old school, I guess. FWIW, AVON's fitment specs shows the 100/90/19 (or the 4.10/90/19) fit a 2.15 to 2.75 rim.
I've asked so should have something tomorrow.Details, pictures, sizes, etc please !!
Interesting, two sites: http://www.avonmotorsport.com/ https://www.avontyres.com/en-us/
RoadRider and RoadRunner both exist.
Fast Eddie's picture of an AM9 looks close to a Dunlop K70 (they do call it a retro design) and they are RoadRunners. The RoadRider MKII looks similar to the AM26 RoadRiders I've been using.
Before someone corrects me - I know nothing about this - I simply buy AM26 tires (or for the Brits, tyres);

Not a chance. If I go back to Avon's it will be Roadrunners for the mileage.
