hello everyone! This seems to be a really informative forum, found alot of interesting threads. Well I own a 2007 GV and so far I enjoy the ride, ( have been riding for a total of a month so far.) I bought this scooter used from a scooter dealer and i have only one complaint and that is the ride is "bumpy", I believe its due to the tires being chopped. I ride back and forth to work which is 12 miles each way . My question is what is a good replacement rear tire and how limited are my options? I plan on riding this scooter alot through the summer to work and everywhere else. Again great forum and I hope to be able to contribute to it in the future.
