If you use radials with tubes, make sure that they are tube type radial tires. 99% of radials available are tubless, and are not intended to run tube in them. I've seen too many tubless tires that have had tubes in them blow out due to internal friction, even with the so called "radial tubes". That name is somewhat of a misnomer, those tubes are not meant to be put in tubless tires, but rather tube type radial tires. So please, use caution in your tire and wheel choices.
