The type of tire certainly will be part of the noise level.
I have the Road Machine-- and I think it is installed correctly.

The bike I have on it is a road bike-- with normal road tires. A second dimension to me not using the trainer is that the bike has a carbon frame and I just don't feel like this is a good combo (trainer + heavy rider).

While I *could* get another cheapo bike to put on the trainer, I'd rather just spend the money on a spin bike.
