Actually it is almost an inverse relationship compared to your age. When you are younger (and smartest of all) you use 100% nitrogen and then as you age and get dumber you get to the 78% nitrogen level. I am at the dumbest point to as I also use the 78% stuff. Good stuff - I sniff it too!

Some nice responses here y'all.

Nissan wasn't the first to do the individual tire display as far as I know but no matter. Why the systems are integrated differently among brands or worse yet among models just pisses me off. Having worked in that line for a while. We would see system mod X on our spec sheet and it would have a feature list - and by damn if you didn't know someone working on a different model would have the same box but a updated feature list.

LIke TPMS - pissed me off no end that the 2012 focus we had only gave a NOID light for TPMS. In 2012 for crying out loud. I know full well that out of the box there is a number of CAN bus data bits it will present for use and you have to use them. It's like this on other cars too. Take the concept of an Engineering Mode (or MX mode if you will) and have a set of displays that you activate via some command set - so you can read on your gage things like I don't know. Fuel burn in gallons/hour or minute or hell L/ minute if that's your thing. OR Battery % via the BMS with voltage, current in or out. All these things are available to your Body Control Computer.

Either way yes that would be a nice feature - as long as you had stock tire sizes.

I love it when I rotate my tires. After a two mile (or so) run, the truck automatically relearns where the tire are. Brilliant!

that's why i said "one of the first" ;) and if you can find more than 5 car makers that did it before 2003 i would be shocked

I had a car when the tire went flat at highway speeds it went "wop-wop-wop" and it would fling pieces of rubber to let you know you had a problem.

That's a great feature, so you don't over or underinflate your tires that much initially, but I'd absolutely use an accurate gauge to set pressures precisely. The TPMS in this truck is pretty accurate, but it still adjusts pressure to 68ºF. And I have no freaking idea why the hell that is. That means at 68ºF, it's dead accurate. But in summer, where it's 90 to 100+ here, it was always 2 to 3 psi off, which is consistent with the rule of thumb that every 10ºF difference, pressure changes 1 psi. Not a big deal, but it pays not to rely on TPMS to set pressures indeed, just like the manual suggests.

Maybe that's my problem... :eek:
