Also a tire that is "aged" will also be slightly better. When you buy "fresh" straight from the factory the tire is not as cured as a tire that has sat on a shelf for a little while. I felt the difference between a brand new tire and last years stock and the older tire was firmer in the tread and and sidewall. It is also possible the the batch of rubber could be different but talking to my tire guy he said it is very common for an older tire to be firmer.
