A Facebook post on one of the LEAF groups asking about the low tire pressure symbol on the dash. More than a dozen chimed in that they also saw it as well and its Winter which is a bit concerning. Like all dash warnings, they come on when the situation is quite dire. Since Nissan already low balls the tire pressure recommendation is it imperative to check those pressures EVERY time you drive the car.
The new LEAFs makes it easy. Starting in 2018, Nissan started listing individual pressures on each wheel and these are self registering so no need to keep track of the changes in position when rotating tires. Like all TPMS systems, it takes a few seconds for the tires to measure the pressure but this is something you should do before traveling too far.
To access this menu option, use the steering wheel buttons to scroll horizontally thru the options. The one you are looking for is the one just left of the options menu or the "Information" screen. Notice the vertical dots on the left side of the display? Those represent how many subcategories are contained within that menu.
The information button has 4 subcategories and two of them should be used frequently. The Trip computer is my default screen which makes checking tire pressures that much easier since its just a single click up to see the TPMS screen
Spread The Work!
Ever wonder why birds fly in formation? Its all about efficiency. If you had to flap your arms for weeks at a time, you would understand. The lead bird faces the most resistance due to air currents. When breaking that resistance, the bird creates a wake of lower air pressure where birds following are able to work much less to follow along. Each bird takes its turn leading so no one isover fatigued and the entire group benefits.
Your tires also see this imbalance. Your front tires guides your car. This means all the inertia your car has is applied to the tire every time you change direction (which in the case of the typical WA freeway driver is every .4 seconds!) which means they wear out faster. They are also the drive wheels and as we know, the new LEAF will spin them tires like crazy. So I would be amiss if rotation was not mentioned. To get the best tire life, you should rotate your tires regularly.
So the only real question is how often? The answer is "often enough to maximize tire wear but not often enough to be an inconvenience" Now what this doesn't mean is rotate them when its convenient. It means setting a schedule based on something. The easiest way is by mileage interval. The LEAF even has a maintenance setting where you can set reminders to rotate when a certain mileage is obtained.
Since I average 15,000 miles a year, I rotate every... 4, 5, or 6,000 miles. Why so inconsistent?
Miles are only equal in length. The wear on the tires is not. Freeway driving provides a lot less wear on the tires. A good example would be Steve Marsh; the "100,000 Mile LEAFer" whose OEM tires lasted him over 70,000 miles! And he kept his tire pressures between 38 and 39 PSI so not even an "extremer"
So based on that; in Summer, I rotate every 6,000 miles due to a MUCH greater portion of freeway driving due to road tripping. In Winter, its more around town driving which wears out tires faster so it 4,000 miles so it averages to 5,000 miles a year. How you do it is up to you but do it!
