Another Can't find tires for my bike thread

[nautec]

I am now going through the troubles everyone else is having now. Can't find tires and tubes for this bike. So here is what I got so far.

JCWhitney has the Kenda K671 front (100/90/16) in stock since it has been mentioned before that this size fits without a hitch and a K671 Rear (130/90/15) in stock.

JCWhitney refuses to help me look for a tube because they claim that the tire is tubeless and a tube will not work. So I am at lost trying to find a right tube through JCWhitney.

BikeBandit has a Michelin 100/90/16 tube available but no 130/90/15 tube in stock.

JCWhitney sells the 16" rim strips but no 15" rim strips.

So my question are:

A) The Kenda K671 (100/90/16 & 130/90/15) should work right?
B) Where the heck can I find a 130/90/15 or MT90-15 inner tube?
C) Can I use a 16" rim strip on a 15" rim if trimmed down? I don't have any experience with rim strips.

Since this is my first bike and I noticed there are cracks in the sidewall and I have no experience with motorcycle tires, any help is appreciated. There is no Suzuki dealer in Tucson, AZ and all the local stores would have to order. Since the tire pair cost $102 and most dealers in town want to charge that for one tire, I am trying to order everything online. Thanks for the help!
