Quick review/search performed:
• Bridgestone Turanza (Web reviewers/forum readers say they’re no good!)
• Michelin Defenders (Expensive and forum users say there is a noticeable drop in range)
• Michelin Primacy MXV4 (User replaced Ecopia with this tire.) (Drop in range)
• Toyo NanoEnergy2 (No research performed)
• Pirelli Cinturato P7 (No research performed)
• Goodyear Efficient Grip (No research performed)
• Continental ProContact with Ecoplus (No research performed)

• Goodyear Fuel Max (Owners seem to have had problems with out-of-round tires)

I was able to make a decision on the Michelin Energy Saver A/S relatively quickly based on the information I found in this forum and elsewhere on the net. Seem like it’s the best all around tire for the LEAF and I need to get the Ecopia’s off the car ASAP.

Re: 2012 Nissan LEAF Tire Replacement Research

I don't recommend the Goodyear Assurance Touring tires. I have two on my Leaf. I had a flat, and it was the only tires that Sam's Club had in stock at the time. I should have shopped around further, but was stuck without a spare. The tires seem to have good wear, but they are loud and vibrate the front end at 50+mph. I thought the vibration was something else, but I can see that the two remaining Ecopia tires are quite a bit quieter, now that they have been rotated to the front.

Re: 2012 Nissan LEAF Tire Replacement Research

One tire I don't see in your list is the Kumho Ecowing KH30. I replaced my Ecopias with them at about 27K miles and have been very happy so far (after putting 8K miles on them). Average efficiency only dropped .1 m/kWh (from 4.4 to 4.3) and they are quiet, grippy, and seem to be wearing well after one rotation. On sale ($100 rebate card), they were $467 at Discount Tire for all 4 w/ tax, mounted and balanced w/ TPMS rebuild kits (and free rotation, balancing, and repairs for the life of the tire).

Re: 2012 Nissan LEAF Tire Replacement Research

Two good tires added to the list and thank you for the additions!

I had the Michelin Energy Saver A/S tires (205/60/R16) installed yesterday and all I can say is WOW, what a huge difference they've made! Road noise is greatly reduced and the overall ride, steering and stability of the car has improved greatly. I'll update if anything changes but one day in and I'm very pleased.

These came on my 2013 LEAF SL, in size 215/50 R 17, V rated. I'm very happy with the combination of handling, steering feel and economy afer 2,400 miles.

Re: 2012 Nissan LEAF Tire Replacement Research

I've been satisfied with the Ecopias, especially since I increased the tire pressure form ~43 to ~48 PSI.

As that may indicate, I am primarily interested in getting the maximum efficiency tires available, to replace them.

Anyone know of any options that might give better efficiency than the Ecopias?

Re: 2012 Nissan LEAF Tire Replacement Research

Only if you don't want them to do any of the things that are expected of decent tires... :lol:
Look at CR's report: The Ecopias were dead last in every category except rolling resistance!

Re: 2012 Nissan LEAF Tire Replacement Research

I have a new leaf with ecopias. I've put 3500 miles on them and they have been good so far. About what mileage can I expect to begin seeing problems?

My OEM Ecopias are fine at 23k miles, with 5mm tread left. No need to look for problems.

If you drive mostly on the freeway, apparently At about 90,000 miles...
