There is no such thing as "low profile" bicycle tires. All bicycle tires are 100% profile meaning that they are as tall as they are wide. Low profile means that they are wider than they are tall but the only way you can make this happen is by having some stiffness in the construction that resists the force of the internal pressure to evenly expand the tire in all directions. Since bicycle tires are so light in construction there is nothing to resist even air pressure. Maybe a thick tread can change the profile slightly and as it wears it will wear the profile "flat" but this is minor and not a "feature" of high performance road tires.
