Max pressure is 110 psi cold for the 614's. Load inflation tables are used by many to determine the proper pressure for the respective load. I carry between 100-105 psi cold pressure on ours and via the TST tire pressure monitor have seen the tires go up to 118-125 psi on hot days. I would venture to say that the manager you had a discussion with is not very knowledgeable.
