Sailun eRange tires

[DougWantsALeaf]

So I have the eRange tires on the 2019 SV+ now. I was away for a week (tested a Bolt), so got to this a bit later than expected.

The eRange tires cost my $108/piece from Walmart on sale. 205/55/r16.

I took an initial loop at 60mph for 4.7miles/kWh (63F ambient) which was close to my tests with the old ecopias late last year. I need to do another side by side with both Leafs.to get the comparative test. At 60mph, the GPS speed bounced between 58 and 59 mph.

The grip and steering response with the tires on dry surfaces is good and you can kind of feel the reinforced sidewalls when driving compared to the ecopias.

I will report back once I have more data.

nice report...I have 30,000 on my Michelins....looks like they can easily go another 10,000 +. Interested in your testing results.

Thanks!

I am starting to feel very old that new eco tires are exciting.

I did a similar loop this morning at 55mph and 70F. 5.2 m/kWh per dash. 169 whr/mile per Leafspy....which feels low.

The loop has you get off and back on to come back and not quite 20 miles, so a little penalty for coming to speed 2x in a short distance.

Roll down test (there is a gentle hill in our neighborhood) was pretty similar to the ecopias.

Road noise is anecdotally modestly better than the ecopias. I don't have anything beyond my ears to verify it though..

Now for a 70mph test.

Ok, ran my 70mph test keeping speedo at as close to 72 mph as I could (which is 70ish gps..interesting g that leafspy seems to reflect GPS speed, not speedo). I reset my efficiency when at speed and had only the 1 turnaround deceleration and acceleration at the far end of the loop. 70F ambient.

Over all efficiency 3.9-4.0 miles kWh per dash. Lesfspy which included some non highway was very close at 253 whr/mile.

This is maybe .2 off of what I would have saw with the worn ecopias. (Guessing)

Prior to the test my overall average for the past 10 days including the previous 55mph range test (240ish miles) was 5.8 miles/kWh. Very similar to my previous summer local and gentle highway driving average in previous summers.

First real rain in Chicago in over a month. The eRange tires did well. Lots of confidence with the traction on wet pavement.

I had a longish drive to the western suburbs yesterday hich included a relatively a unimpeded 35 mile stretch of freeway in both directions going pretty much straight west then straight east. 69-71F and a 10 mph wind going towards the east

Tried to keep it at 70mph going out as possible and ended up going a bit faster the way back due to fast moving traffic.

Outbound was 3.6 miles/kWh. And return was 5.0-5.1 which translates to 4.3 miles/kWh average. That's fairly close to what I was seeing with the ecopias for this stretch.

I think the bigger question now is how do the tires do when it get cold...and snowy. We have a few months for that.

I am disappointed in the Conti ECO tires- brand new and over the first 1K miles I see 3.5 m/kWh whereas with the original Ecopia tires, during the previous month with essentially the same driving patterns, we were seeing 3.9 to 4.0 m/kWh. Tires are the only variable..... the best I can hope now is that they are tougher than the Ecopias (2 of which had road hazard issues) and last longer- the reduction in efficiency may possibly cost less than replacing tires at more frequent intervals. Continental does have an 80K mile warranty (for what that is worth) and they cost over $100 less than the Michelin for 4 tires. No issues with handling but we drive like old people anyway.

Hello, it seems like you know about tires for the Leaf. I have a 2020 Leaf SV and I can't find decent price tires. The ecopias are out of stock, the sailun you have don't fit my rims (215/50 R17). It's hard to know what tires might work as EV tires. Can you recommend any options. Thanks!

It looks like they sell that size.

As a heads up, I don't know yet how these tires do in snow.

I have about 2k miles on these tires, and still very happy (in warm weather). The combination of grip and efficiency is pretty good. Above 80F the efficiency is extremely good.

I just cringe now when driving my.other Leaf Plus with crossclimate2, and only able.to get low 4s at 55-60mph.

We bought 4 new Continental tires that are supposed to be designed for efficiency, and immediately saw a reduction in range from around 3.9 wioth the original Ecopias to around 3.4 m/kWh. No other variables came into play so it is hard to recommend the Contis. For better or for worse, they are supposed to last really well....
