Finally had to retire (pun intended) my 21"s as they were down to less than 3mm. Replaced them with 19"s

As requested here is another update. Still trending down on the average lifetime energy (from 320 at first report last summer). Just had second tire rotation at one year service and tire wear is still reasonable on the 19" Goodyears.

13,135 miles 4,112.6 Wh 313 Wh/m lifetime average

Update: As of July 4th we're still trending down (with last 1000 miles at only 304 Wh/mi.) Totals now are:

16,699 miles 5,197.9 Wh 311 Wh/mi lifetime average

Tires have 7/32 inch tread all around left on the factory 19" Goodyears as measured July 2 by Tesla service center. Northern CA.

Not really related to average, but here is what happens to power consumption when stuck in major post 4th of July fireworks traffic!

Here's how bad it got!

This was the rated miles at that time.

Once out of the traffic it recovered quickly.

361 over 18,000 miles in Portland, OR. It's about 425 in the winter and 330 in the summer.

Rain is definitely a big factor. Even warm summer rain drives it up 30+ wh/mile.

Just under 4000 miles, 285Wh/mile average. AZ environment, A/C always on 72-74F, radio, lights. Mixed hiway and city, relatively flat.

Canadian SIG Experience - Summer 21's and Winter 19's

Daily Mixed Highway and City Driving - 2013 / 2014 was a cold winter!

Last 5,000 KM (on 21's) - Average 170 WHr / Km = 274 WHr / Mi
25,000 KM (on 19's Winter and 21's Summer) - Average 203 WHr / Km = 327 WHr / Mi

Interesting. I drive like a jerk and I'm getting 367. P85, 21" wheels, Continental tires. Made in June 2014.

Update: Oh. Duh. Right: higher is worse. Never mind.

Wow! How do you do that?

Wow! How do you do that?

You did notice the "per km" part, right? That silly rest of the world with their logical, easy to use unit system...

D'oh! Thanks, totally missed that.

Totally OT, but speaking of metric -- isn't it odd that we still have "imperial time" units? 60 seconds per minute, 60 minutes per hour, 24 hours per day, 365.24 days per year. There are reasons, all having to do with history and convenience and compatibility, but you could say the same for any other unit. It's a little surprising there wasn't some brave soul arguing for milliyears or kiloseconds.

FYA, I've written timekeeping code for operating systems. You can't believe how awful the problems are. For example, a day is defined to be 86,400 seconds, and it is also defined to be one Earth rotation. But the latter actually changes with geological events. The Sumatra-Andaman earthquake of 2004 shortened the average day by almost 3 microseconds, which may sound like nothing but is a real headache for high-precision timing.

The real problem is that the day, like many natural situations, doesn't provide very useful increments when divided by ten. An "hour" (day-tenth) would be a bit longer than two hours, a "minute' (day 100th) would be slightly less that 15 minutes, and a "second" (day 1000th) would be about a minute and a half. So "hours" would never get used. I'd much rather see a metric system in base 12, then things would work correctly.

Oh, dude. If we get to contemplate that level of cultural reset, do everything in hex. As bad as time issues are, the fact that 1024 != 1000 is a disaster. Having a number base that is not only a power of 2, but a repeated exponent of 2 (16 = 2^2^2), would be paradise.

I love this forum.

I could deal with hex too. Mostly we have base ten because some dull person counted on his fingers and couldn't make the transition to use his too feet as well.

Good month thanks to Spring-like weather.
