Hey guys, Glad to jump into this thread. I was wondering if any of you have experimented with these vintage style Firestone tires that I have seen on all the Zero Engineering Bikes. http://onlyoldiesgarage.com/xcart/pr...roductid=16438 I have thought about putting them on a Harley Davidson Sportster 48 or Royal Enfield Bullet 500. Although, I am afraid RE 500 might suffer from a really screwed up alignment of the frame. Yes, this is purely for aesthetic purposes and giving up a bit of ride quality is a sacrifice I am willing to make, but not too the point that it is intolerable or deadly Yeah, I see those a good bit on bikes, but I have no personal experience with them myself.
