No chance - from what I've learned about local authorities/ municipal councils/ the borough in charge of road repairs in any country ive ever been to is that they would rather pay for road-related car damage claims and back-fill their pensions than actually fix the roads... and let's be honest, the I-Miev doesn't like pot-holes much.

Bought the Continentals for the fronts.
Nice tires.
Negligible effect on regen or range.
$190 for both.

FWIW,
I just purchased all 4 Yokohama Avid Envigor tires in stock sizes from Simpletire.com for $290 total delivered to my local Pep Boys. Pep Boys charged me $90 to mount, balance, TMPS service etc. About $380 all said and done vs. a $620 quote from Les Shwab and a $740 quote from discount tire. I cant say much about the mileage and handling yet but the grip is worlds better than the stock tires that were down to 4/32nds after only 33,000 miles.
Anyway, thanks for having such a great forum. I have been lurking for years, made my purchasing decision from the information here, and have had many questions answered by poking around.

Donny, welcome to the forum and glad it is serving you well. Good price for the tires and thank you for letting us know. You'll probably find a slight increase in tire noise and a slight decrease in range compared to the OEM Dunlop Enasaves, and as long as you keep the tire pressures below 40psi you should be fine. Incidentally, some of us consider 33,000 miles on the OEMs as pretty good.

Thanks Donny, glad to hear from you, and from the Les Schwab mention- you're in the Pac Northwest? It'd be great to have more i-MiEV representation at upcoming Drive Electric Week Events.

I think 33k on the original front tires indicates a very gentle driver. :mrgreen:

My car has 26k miles on it but the tyres have been replaced at least once (in 2015) and the front ones are feathering on the edges.

Being in the UK, we have EU tyre labeling which claims to rate the efficiency of the tyres.
http://www.blackcircles.com/popups/eu-tyre-label

The hankooks (which I currently have) have a rating of E

http://www.blackcircles.com/catalogue/h ... e=31666146

and the yokohamas have a C rating (better)

http://www.blackcircles.com/catalogue/y ... e=32362942

Think I may go for them - they stop better in the wet too!

These rotallas have the same rating too but I'll probably go for the yokohamas.

http://www.blackcircles.com/catalogue/r ... e=34927485

Any experiences with any of these?

Thanks

I just had 4 new Yokohama Avid Envigor tires installed on my car and wow are they quiet. I've had them now a month. The old Dulops Ensaves had just over 24,000 miles and would have been good for a little longer except the left front was tire wearing on the outside edge. I've been running the Dulops at 42 psi but while driving home on my new Yoko's at 35 psi I really liked the quietness and the softness of the ride so I raised them a small amount to 38 psi and it still runs at the same quietness. They're not as sporty at this low of pressure, as the cornering is not as quick and I can hear noticeable tire noise when doing so.

As for fuel economy, I'm not so sure there's that much difference. Round trip to work and back (about 33 miles) costs me 8 or 9 bars from a full charge with either the Dunlops or the Yoko's but it's funny because the range remaining gauge says I can only go 63 miles on a full charge now compared to the older Dunlop's 70 miles range. Not very scientific but I think tire diameters are just different.

I took the car to Oakland Mitsu since I was trying to throw a little business their way after my big battery change out last March (which has been working great btw) and 4 yoko's costed me $589 vs. $720 if I got the Dunlops. But I checked around and the price was about the same wherever I looked. In California we have tire disposal fees and other taxes which makes them more expensive than some other states. The great thing is that they checked my alignment for no charge and said it was still within specs from last year.

New tires are always significantly larger in both diameter and circumference than old worn tires and that throws lots of things off. Since the speedometer and odometer are almost always based on the number of revolutions a tire makes, both those change when you install new tires. The effective gear ratio also changes which affects fuel economy

When you wear a tire down from 10 or 11/32nds of tread down to 2 or 3/32nds, you've worn away around 1/4 inch of tread and the diameter of the tire is 1/2 inch smaller, which makes the circumference about an inch and a half smaller . . . . and that changes just about everything

Going from LRR tires to non LRR tires could make an even bigger change - An estimated loss of fuel economy (range in our case) of about 4% for urban driving and 7% for highway driving

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