That's interesting. An inch and a half on each revolution probably really adds up. At least until the tire wears down some. 8-)

I don't have real numbers, but my buttometer agrees.
I'm running three different sets of tires on three sets of rims. The worn-down originals on alloys, which have about one more summer left in them, the steelies from Ben's SuperStorm Sandy-flooded project car, and a set of studless snows on alloy rims.

The worn tires on alloy rims are noticeably quicker, as they weigh the least and have less diameter, but that also contributes to an exaggerated reading on the speedometer.
The steelies with good tread are middle of the road.
The winter tires are lowest performance, given their squishy deep tread, but snow traction is excellent.
If only I had idle time at the drag strip to chart all three....

Well, I went ahead and placed an order for the Dunlops (in part because I hadn't yet heard back any replies/strong-opinions from you guys).

FWIW, I did so on (a) the "better the devil you know" theory, and (b) that arguably the Dunlops should get a bit better range than the Yohohamas, and (c) evidence from my existing rear Dunlops being run at 45psi that the new ones should be good for about 35,000-40,000 miles. And (d) Les Swab knocked of $20 from the Dunlop price to match what Discount tire offered me.

By the way: I was initially leaning to the Yokohamas in part because of their 60,000 mile warranty. But it turns out that that's misleading.... because Yokohama (and indeed most tire makers) won't honor their mileage warranty if you're not doing four tire rotations (which of course we can't do.) At best they'll give you half, and worst they'll void it completely.

Just FYI: I have Continentals on the front... put on about 10,000 miles ago.... due to fronts being out-of-toe (unknown to me) from day one dealer-new-delivery and prematurely wearing edges down. IIRR that happened to a couple of other folks here.
The Continentals are wearing and running well and I'm happy with them and their price. Too bad they don't make them for the back size.

Also, FWIW: My experience with Les Schwab is they're real good about free flat repairs and honoring their road hazard warranty.

Joe had a set of the Yoko's on one of his cars for the full life of the tread and he wasn't very happy with them. I know he strongly felt they cost him a bit of range and the studies show that should be the case - Using non LRR's should cost you 4% in around town driving and 7% on the freeway, or so says Tire Rack at least

I've used Yoko's on several ICE's for many years and like their wet weather performance, but as much as I may like them, I don't think I'll ever put them on either of our EV's - I'll pay the extra and stick with LRR tires for the added range . . . . and because Mitsu says that's the tire type we should be using

Thanks Don...

Your reply give me a bit more confidence that I made the right call spending a tad more for the Dunlops.
4 to 7% more range is significant... especially as our batteries get older.

And you did remind me to consider Yokohamas when our Subaru next needs tires.

Not available in our size, but two of my other cars now have the LRR Nokian Entyre. I'm quite pleased, though there seems to be slightly less grip than the Goodyear FuelMax that they replaced.

OK, I am no longer obsessed with -

Low Rolling Resistance, as I almost never push the range limit
Tire Noise, as I don't drive long enough for that to bother me
Handling, as the i-MiEV's low CG compensates for other perceived shortcomings
Grippiness, as it rarely rains around here and my worn-down slicks work just fine on dry pavement
Speed Rating as I don't hang out at 81mph for long all that often

I just want some inexpensive tread on my i-MiEV to complement its otherwise ridiculously-low operating cost!!

Two questions -

1. Where do I look to find used i-MiEV tires and wheels from all those salvaged wrecked i-MiEVs?
2. What brands in our tire sizes have y'all purchased in the US recently?

Where I'm coming from: using CraigsList six months ago I bought two beautiful used rims with almost-new Michelins for my Tesla for $100 each (no, they weren't stolen).

After all, I was born in Scotland... ;)

Well, since you've 'eased up a bit' on what you consider important . . . . and since you live on a twisty road that can be fun to drive . . . . and since you *like* to push the car a bit on those fun roads . . . . and since you're obviously getting tired of buying new tires every 20,000 miles, it may be time for you to think about making a major change

If you were to get a set of 15 X 5.5 Mini wheels, add longer studs so you can mount those wheels with a 9 or 10mm spacer behind them, you could put some real tires on the car which would dramatically change the way it drives . . . . and your tires would probably last you lots longer than 20,000 miles because you wouldn't be scrubbing off the rubber sliding sideways on those fun roads. There are lots of OEM Mini alloy wheels on eBay for $65 to $75 each with free shipping - You might even find a set of 4 locally for less than that

If you doubt those fun roads are where your rubber is going, consider - Our first car now has 35,000 miles and I changed the front tires at 10,000 because I had a blowout and the tires on it still have an easy 10,000 or more miles left in them. Second car has 20,000 miles on it and the tires are *maybe* half worn. No 'fun' roads around here :cry:

Might I suggest a set of 175/55R15's on the front and a set of 185/60R15's on the back? Continental ContiProContact makes both tires in those sizes and Tire Rack has them in stock. Those sizes will fit and the car will *like* them and there's no problem with regen not working

We know that keeping the stock front tire size and changing the rears from 175/60 to 175/55 like the Euro cars came with does NOT work on North American cars and regen is disabled. I think this is because that makes the rears 3% too small (in diameter and circumference) and the cars computer *thinks* the rear end is losing traction because the rear tires are spinning faster than the fronts - It disables regen because it doesn't want to make that slippery situation in the rear any worse

The 175/55's I suggested for the front are just 0.7% larger than the stock size and the 185/60's I suggested for the rears are just 2% larger than the stock size, which gives you a net difference of only 1.3% larger in the rear - The car will easily 'buy' this difference - It doesn't like smaller rears, but it's not so choosey if the rears are a tad larger. Speedometer and overall gearing remain correct within a percent or two

You will *like* your new 'sportscar' if you try this Joe - Guaranteed! I already have a set of Mini wheels and I won't be far behind you on this project - We have a couple of upcoming trips so I can't do anything before May, but I'm gonna do this too

Don, thank you very much for your informed suggestions, which will certainly be cost-effective compared to OEM tire replacement. We're taking off in the Tesla for another 1500-mile trip for a few days which will give me some time to research wheel and tire availability, as I have no reservations about modding my i-MiEV.

My featherfooting wife's i-MiEV's tires barely shows any wear compared to mine for the same mileage, so I am under no illusion that it's my uninhibited driving that's the culprit.

I'm now getting 21 listings for salvage alloy wheels on http://www.car-part.com most in the $100-$120 range. My french isn't good, I'm betting that the $40 listing is for wheel covers instead.

But NO tires. My local salvage yard has a subcontractor strip tires and haul them off as soon as a hulk hits their yard, and then there's no tracing them. Shame, as they'll languish as oddballs at a used tire dealer.
