Yes. Buy the tubes that correlate with the width of your rims.
For example, I bought new tires and tubes and rim strips (don't forget those, Hyseman. They're only about a buck a piece) from Dennis Kirk this summer. I bought a "Drag Specialties" 19 inch tube Dennis Kirk Part #: H53011 which fits 3.25/3.50 Tires, and 18" inner tube (Dennis Kirk Part #: H53003) which fits Fits 3.50/4.00 Tires. They fit perfectly and seem to be quality tubes. $10 each. Hope this helps.
