I've run pressures at 100 and 110 (my usual road pressure). 23mm GP4KS on a Hed C2 rim. I've cranked down to as much as 4 full turns and I can make it slip from a stop or from a spin if I shift and stand. It doesn't slip during steady state work just at the first kick of any sprint. Maybe this is normal? The responses above seem to indicate a specialized trainer tire isn't worth it. I can buy a cheap tire and put on an extra rear wheel I have.
