I disagree with a lot of what has been posted, and would answer the OP's question simply by saying no, new tires do not roll faster than worn tires of the same make.
However, what the OP has done is to switch brands, so in that case, the more likely explanation is better casing and tread on the new tires.
Harder durometer rubber, more supple casings, and higher pressures generally have lowest rolling resistance. Look for tires with high thread count casings, dual compound treads (hi-duro in center, lower on shoulders), and light weight (indicating less treading) if rolling efficiency is a priority.
