Re: $20 Wheel master rims.
consider using road tires in stead of cruiser tires which are actually meant for sand use. Loose particles in the road are a hazard for any rider including motorcycles. a wider wheel under the back even though the tire isn't any bigger it gives a bigger profile where the rubber meets the road and thats the most important thing. I have ridden road tires in the rain and they were just as good as the sand tires.
Ride it like you stole
