Agreed. The Moose Test was actually performed with a small battery 63kw Ariya trim fitted with 20” wheels. Logic suggests that the 19” wheels/tires we are discussing here won’t perform as well as the 20’s that were applied in the Moose Test. You mentioned the early Ford Exploder having a tendency to roll over, I suggest the same treatment that Ford recommended then applies here for Ariya as well. ie better control in an emergency maneuver when tires are inflated to the lowest reasonable value. So just another reason I favor 38 PSI for all Ariya FWD as the target pressure.
Regardless Nissan‘s motivation in the US market to recommend Venture tires be inflated to 46psi is merely done to attain a target EPA range rating. By comparison recommended inflation values for Ariya FWD trims outside the US market where EPA ratings have no impact, are guided entirely by engineering logic and not skewed by any EPA parameters.
To that end some consider that the EPA has evolved into a bit of a monster. (Heck it was Richard Nixon’s brainstorm, so why question the value of the EPA, right?) Seriously the EPA s ability to generate valuable data is not on trial here. However, the down side to the EPA information is that many Americans (including myself at times) consider EPA information to be the best source in the US to evaluate data and ultimately arrive at a final decision making conclusion. Unfortunately since the EPA data in the Ariya example seems to have become skewed a bit by Nissan, there may be a few Ariya Venture buyers out there that may wished they had considered higher trim levels. That said I contend if a Venture + and Evolve + trims adjusted tire pressures the same, drive the same road under the same conditions (no drafting) even though the Venture + weighs 80 pounds less, range results would be identical.
