IMO you can't trust those reviews much. The majority of people out there are probably running around with 20 psi in their tires and don't know that they're doing major damage to them. I also run a dedicated snow tire, so I ignored the snow traction. Also, if you read the reviews with more miles on them, and the ones that aren't aggressive drivers, those people loved the tire.
In any case, I'm sure most of the tires out there roll great when they have 50 psi in them. I try not to get too hung up on LRR, but you do wanna buy the best when you have the chance!
