The Diamaris is less so due to it's summer only rating, and I would assume that it's a better dry grip, turn in, handling etc tire. To what degree is up for debate. But it is aimed for the performance SUV market for max performnance. The latitude is compromised by it's all season performance (rubber must remain softer at low temps, must be able to handle at least light snow, has to do well in rain, max grip is down on the list. Trust me through, we never come close to a tires potential on the street. Ask anyone who has participated in a track day. What these tires do for untimate grip is amazing. The higher treadwear tire may be the right choice for most folks. Again, just my opinion.
