I ran into someone at Watkins Glen who was running 32 psi hot with NT-01's and he also said the grip was great. He had very fast times in his e92 M3. He didn't say anything about wear.
I am still running 38 hot and getting great wear ( chamber -2.2F) and the grip is fine for me. Might try the lowering the psi once, but expect I would be trading off wear and life for it.
