If most of your driving is on city streets and the freeway you won't notice the wear as much. I drive on a country road laid out by a drunken cow. I usually wear out a set of tires before half of the warranty miles on all my cars. Just twisty roads. Driving in straight lines is much easier on the tires. If the pressure is too low you wear the edges out because the center tread isn't bearing enough load. A few PSI is enough to make a significant difference in wear.LeftieBiker wrote: ↑Fri May 08, 2020 10:25 pmI don't strongly disagree, but I ran my 2018 with 38psi for the first Summer, with no issues. At the first tire swap I raised it to 42, letting it drop to 40. I didn't do much hard cornering, though.johnlocke wrote: ↑Fri May 08, 2020 8:33 pmRunning a tire pressure lower than 40 psi runs the risk of excessive wear on the outside edges of the tire and poor cornering due to excessive rolling of the tire. Nissan used 36 psi to soften the ride at the expense of tire wear. 40-42 psi seems to be the sweet spot.
I agree, different cars hide different amounts of energy. My SL Plus shows the first low battery warning with remaining energy equivalent to between 35% and 40% of the full capacity of my two previous cars when their batteries were new. There is more energy remaining in the 2019 SL Plus when the dashboard display goes to ---% SOC than the previous cars had at the first low battery warning. I just drove it 29.6 miles after the first low battery warning (LBW happened at 6% SOC and 11 miles remaining according to the dash display with Leaf Spy reporting 106 Gids); 20.4 of those miles were after what is generally considered very low battery warning (VLBW was when remaining miles went to --- at 2% SOC on the dash with Leaf Spy reporting 79 Gids); and 13.7 of those miles were after the dash SOC display went to ---% (Leaf Spy reported 64 Gids at the point when the SOC dropped from 1% to ---%). In order to do my quarterly full discharge/charge test I ran climate control in the driveway to Turtle (happened at 12 Gids) and Shutdown (7 Gids).LeftieBiker wrote: ↑Sat May 09, 2020 5:47 pmI think that range tests should include not one, not two, but three numbers: Range to Low Battery Warning, range to Very Low Battery Warning, and range to Turtle or equivalent extreme power reduction. If there are no low battery warnings, the car should be tested to whatever warning exists, and to turtle.
Efficient right up to the point until you skid on a wet road and hit something....or can stop soon enough on a dry road due to the reduced contact patch.
