I am using a CycleOps FL2 trainer also, every day for one hour as my exercise. I do not have tire wear.
Using 700 x 38 Bontrager tire and use the same tire to ride Limestone Rails to Trails. I am doing this for over two years.
Perhaps the reason for no tire wear is that I set the pressure of wheel to friction wheel very low. Just as low as I can and still bike at 20 MPH standing up. My regular routine is 17 MPH at 90 RPM. I have also a HRM mounted on this training bike. I am training for XC rides and have done a six hour 100 mile session on this trainer.
This trainer is very reliable and simple to use. I am glad I bought it.
