I have the Avon trike tire on my GW trike and think it's a great tire! Problem is they are very limited in sizes and don't make one for the RSV trike.I don't know what size your front tire is, but I am running an Avon Cobra Trike front tire on my Stratoliner/CSC trike and I love it. Runs smooth, tracks good and I am hoping for good mileage (only have about 3K on it so far). Ran a couple BattleAx rears on the front before this, but I had a cupping/scalloping problem with each tire after about 5K miles. Maybe I just push it to hard around corners, but I will see what this "trike specific" front tire does that Avon came out with. Good luck.
Am in need of a new front tire and was wondering what is considered the best tire for the Venture. Also I'm looking for good quality radiator cover. Oh by the way I have an 08 Venture with a Hannigan kit. Thx in advance!
