Are 17 inch ecopia tires worth it for efficiency?

[Radek Uchytil]

If I were shopping for 17" tires, I would get these:
https://www.walmart.com/ip/Pirelli-Cinturato-P7-All-Season-Plus-215-50R17-91-V-Tire/43082175

Only $90 each and they will have better traction than the Energy Savers and Ecopias at the expense of range.

I have these tires on my Leaf. Driving characteristics are good, but this does not apply to snow. But it does not save energy.

I think of it as a math problem. There is up front cost and continuing cost. The continuing cost is electricity/mile and the fixed cost is the out-the-door cost of the tires. If the increased amount of cost for the more efficient tires is greater than the increased cost it’s worth doing. If it. Isn’t it isn’t . Assuming they both get you where you need to go. The shorter range ones may not. It sort of depends on expected destinations. There is also that borrowing money has a cost too. Is there a high cost loan you could pay down with the extra money the tires cost? If so that savings goes into the algorythm. If 16” tires and rims are bought the rims are a fixed cost as well

I always try to find tires under $100 with the best performance. These labels help us.

There was time a a while ago, when China was trying to kill other brands and was dumping tires. This strategy would have worked real well then as you could get a Chinese tire for less than $100 that equaled performance of tires from non-Chinese brads that were more than $100. Chinese costs are a lot higher these days though and they’re not doing it so much these days. This is not to say it’s bad, just maybe not as good as it was (which was real good)

need new tires, 4x ECOPIA EP422 PLUS (215 /50 R17 95V XL BSW) will cost 850 to install, ugh, are these worth it on the 17 inch rims? from what I understand bigger rims are usually less efficient, I get ok efficiency on my bald Michelin energy savers, does anyone have any experience with ecopias on the 17 inch rims? i would like to get as many miles / kwh as possible.

just noticed poking around the forum, some people have 215/55 R17 sized ecopias on their leaf, hows that working out? they're 20 bucks cheaper per tire and maybe should be a little more efficient because there's less rim to sidewall vs the stock tire size, is there any clearance or fitment issues? On discount tires website it claims they wont fit my vehicle. Im a little worried about it being an SL tire instead of XL tire, not sure how much that matters.

Unless you need the tires right now, if efficiency is what you are going for, I would look for the "Sailun ERange EV All Season 215/50R17 95V XL Electric Vehicle Tire". I have not had a chance to create the topic with my experience because I just finished gathering data today, but they out do the Ecopias by quite a bit. For the longest time, Ecopias were the king of efficiency here, granted they did about average for snow, mud, rain, etc. If you are wanting to max out range, I would recommend them for that only. I can't say much about rain or snow handling as I've not had a chance to test that, so depending on your needs...

Bonus, they cost half as much as the Ecopias currently.

[edit] Nevermind, this was from 2020, well....

On one of the other threads I posted a you tube link where they compared eco tires, and eRamge tires won. They also have far superior handing and grip compared to ecopias. Personally I find efficiency to be pretty similar.

I believe it, my own test show them scoring +0.5 boost to efficiency against the data I had on my Ecopias. It surprised me because I tested them brand new, which is usually when you get the worst scores until the tires wear down a little.

When I moved from my hardened worn 4 year old eCopias to the eRange, my efficiency dropped a bir, but 10K miles into the tires they are much better now.
