My two cents: Have sidecar rig ['95 GL1500/CA Friendship III]. Run Austone rear, from Vintage Tire in OH. Is PERFECT for our rig. We tour New England states each riding season [for 11 years now]. Used several sets of various tire brands. Avon Venom front/ Austone rear is BEST combo, hands down, for us. TTFN...papasmurf
