$110 for a new set of tires with mounting, is a real good price. My last rear tire, a Metzeler Lasertec was $125 for the tire, $22 for a tube, and $20 for mounting and balancing.
So I think you're getting a great deal.
Even if they turn out to be not the greatest tire you've had, it's going to wear out, so you're not stuck with it for life.
Just go easy on them until you learn how they feel.
