They are contradictory, by definition you want higher resistance for traction. I don't like LRR tires on the street so took them off within a few thousand miles of getting my Volt, and unsurprisingly my range dropped 10% or so, but I feel the increase in traction is easily worth it. Stopping distance is improved, cornering is improved, traction is improved on acceleration (used to chirp the tires all the time starting the others were so low traction).
If you want to drive on the track, but keep LRR tire range on the street, get a cheap set of used wheels and put track tires on them, doesn't take long to swap them out before an autocross or track event. However, you have to store them which is the larger pain depending on your situation.
