Staton Inc can hook you up. You can also go to local bike shops as well. I'd suggest using double walled rims. As for tires I personally use Kendra 838. They're patterned after a motorcycle tire. The tire sells for around $17 at Dick's Sporting Goods. Another good tire is the Rubena V99 City Hopper. They have a reflective side wall and come in different colors. The tire sells for about $30. Rubena has a website and also are sold on Amazon.
