    Is the muffler under the pass side?

    Or, maybe a lot lizard!

    Maybe it just occasionally forgets the words...sorry, couldn't resist.

    It might help to know what make/model/engine you have. I know the Maxxforce powered Internationals have a oil centrifuge on the passenger side of the engine compartment that makes a humming sound, but I don't think it's speed related, more RPM related

    I could just be those new caps you put on that side.
    Some tires really hum depending on tread design.

    I think it is the tires. Tires are actually very noisy and make more noise than people think.
