Bridgestone EP422 tires swapped for Michelin Primacy MXV4s.

[TomT]

I have a similar hill I test with which is part of my daily commute. It's a gradual 3 mile downgrade. With the worn Ecopias, I stabilized at 61mph when coasting. With the new Michelin MXV4s, it was 59. Not much difference. Now that they are worn in some, it is back to 60. Keep in mind that the resolution of the display is only 1.0 so the numbers are somewhat meaningless except to show that there is not much difference, and remember that this was with tires with much more tread depth then the Ecopias, which increases rolling resistance.

For rolling resistance test, I have my favorite test hill just a few miles away. I'll be able to tell pretty quick if there is any significant loss (or gain?) of rolling distance.

I've already worn out one set of Ecopias in 25,000 miles on the previous LEAF. Since I do NOT foresee these tires coming close to meeting the lease terms on my current LEAF, and I don't buy new tires for the dealer when I turn the car in, I just bought the Nissan Juke wheels and 215R45-17 Michelin MXM4 Primacy tires to enjoy while I'm driving the car.

Then, at turn in, I'll pop the 7000 mile Ecopias back on. I can sell the Juke wheels/tires for a substantial portion of what I paid for them.

So, you see, there are methods to the madness.

Hmmm... I was hoping the tires would survive the three year lease term; that's starting to sound like wishful thinking. I don't even know what the deal is on tires at lease turn-in, probably just another unpleasant surprise waiting there to reinforce the hard lesson of making a bad personal finance decision in support of a cause.

No, the stock tires won't make it. My under 10,000 mile stock tires and wheels are now in big trash bags, stored until my car is returned on lease. Here's the new Nissan Juke 17 x 7 wheels, with Nissan center caps, plus the Michelin MXM4 tires:

Looks good Tony! Let us know when you have some LRR data!

Well, I suppose I will get a baseline tomorrow, as I have 105 miles to drive to the new Blink DC charger in Diamond Bar, California. I predict a good outcome, though. I don't think I'll come up too short with about an hour of L2 enroute. 45-50 mph is a bit over 3 hours total time.

I drove 160 miles in just about 5 hours yesterday, with about 3 hours of 16 amp charging (I don't know if they were 208v or 240v). Long day of high concentration driving!

Drove the Infiniti today up to LA to pick up the wheels. About 200 miles round trip, about 3 hours 30 minutes TOTAL with fuel stop (10 minutes).

tom and tony,
i take the week-old mxv4s to the dealer this am around 11 for balance check.
what psi are you each using?

How much tread life is required at lease turn in time?

[TomT]

I ran 40 on the Ecopias and initially on the MXV4s bur changed to 44 since it did not dramatically affect the ride, and handling and braking did not fall apart at that pressure like it did with the Ecopias.

thanks.
So, I was up at the tire shop before you posted and went with 40 psi. i will test it out and would like to go to 44, based on your report.
these are much more substantial tires and grippy.
the tire mgr says he doesnt know why they would have more rolling resistance then the ecopias, but noted that all manufacturers are different.
aside from the weight difference, i think the ecopias are not as well constructed -- one of mine had gouges and a bubble in the sidewall.

afterwards, I did a short trip and I was up to getting 5.5 miles per bar at 60, which was a gain.
I need, or want, to get miles per bar for my commute, so i can safely get there and back on days when i am shut out of plugging in.

With the ecopias, I was getting to work consistently -- 25 miles -- using four bars and the psi at 36. There is some slower than freeway driving, streets and, of course, during the commute the freeway rarely goes 60 for very long.

What size tires did you go with, and where did you get the Juke Wheels?
Price?

Thanks
