It's been very hard to find that info. Sometimes you can find it in tire stats on sites like Tire Rack or Discount Tire. Or manufacturer's sites, specifically if they make tires for EVs. Otherwise I guess look for what tires EVs have stock or look for reviews.

Woof.

Also looking at the BFGoodrich Sport Comp-2 AS. I used to have the summer version on my Miata and freaking loved them. Good treadwear, response, and price. But with efficiency being so important on a small EV, I am (maybe too) conscience of the potential range impacts of poor eff tires.

I have an 84mi commute mostly interstate. From everyone’s experience, can tires really shave off 10s of miles? Ie should I be that concerned if the tires are less efficient ?

Haha I also had the Comp 2s on my Miata and now have the Comp 2 A/S Plus on my SE!

They are way better that stock for grip and handling but are horribly inefficient.

The dotted black line is a moving average of my calculated efficiency, it's pretty clear where I switched tires! My worst trip was mostly highway with a strong headwind and I ended up at 2.7 kWh/mi or a max range of 78mi... So yes, unfortunately you should be concerned about tire efficiency.

YOWZA!

That is a significant hit. Snap. Well, now I am quite concerned about not getting an efficient tire… but one that’s not stupid expensive, while still being good in all weather conditions, and still being fun. That seems like something has got to give… can’t have it all.

I ordered my SE with the 17"x7" Roulette Spoke wheels, which came with 205/45R17 Hankook Ventus S1 evo3 ultra high-performance summer tires. (I find it interesting that TireRack doesn't know about this size for that brand & model of tire.)

I love the look of those wheels, but I wish they weren't so darn heavy. My usual preference is:
  1. Lightweight wheels with ultra/high performance summer tires.
  2. High performance all-season tires on the stock wheels (since we usually get more weeks of spring and fall than summer here).
  3. A third set of "minus one" sized wheels with winter tires.
That takes up a lot of garage space, but it sure is nice to perform a wheel swap myself to ensure the best combo when the seasons change.

Since the stock wheels came with ultra high-performance summer tires, and I can't bring myself to spend money to replace those tires immediately (or deal with the logistics of doing that plus moving these tires over to a new set of wheels), I recently decided to take a different approach:
  • I'll keep those tires on these wheels while they're still usable, and replace them with all-seasons when they're due for replacement.
  • Meanwhile, I will get some lightweight wheels and put all-seasons on those. (Especially since fall is upon us now.)
  • I will skip getting dedicated winter wheels + tires for this year. This will help defer some cost, plus I already have a good set of winter wheels + tires for my wife's car. When the weather warrants that kind of equipment, we can just take her car instead.

How did those DWS06s work for you? What kind of range are you getting?

Any tips on where to find the rolling resistance values? The EU label is great, but finding that label/data on say, tire rack, is near impossible.
Click to expand...

TireRack and other U.S. distributors won't show you the EU label, and manufacturers generally don't mention rolling resistance unless they have a new EV tire they want to brag about (typically for SUVs and super-expensive performance cars with fitments that are way too big for the SE). It's much more effort than it ought to be.

I use these 2 sites when trying to find the EU label for tires I'm researching:
Even so, you may not find the EU label for a model which predates the new label requirements.

I actually wound up getting the Michelin Pilot Sport All-Season 4, on both the RSe05 wheels and then my stock Roulettes. Details on highway range impact can be found here: https://www.insideevsforum.com/comm...ous-conditions-cargo.11491/page-2#post-146185 Handling is great (especially with the wider fitment), but at the cost of efficiency. Those results prompted me to be more diligent in searching for EU labels on the tires I'm considering moving forward. I haven't found any rolling resistance values or EU labels for that model of tire, but I'd guess they would be a C or D.

I plan to try some more efficient summer tires on the RSe05 wheels next spring.

Thank you for that great word! Will you become GruntledSanta after your SE brings you happiness through kartiness?
Click to expand...

Hahaha very likely so. PICKING HER UP TOMORROW!!! After 4 months… not that I am excited or anything… it has been 3 months since my Miata sold, so I have had to suffice with sim racing for my kartiness fix. Great fun, but nothing like a kick in the pants of a real car.

This tire issue is slightly stressful, though! The weather here should be unusually warm for the next week so I have some breathing room. Probably just going to shell out cash for a set of dedicated winter tires and wheels (VikingContact 7s). Good price to efficiency trade off. I can’t find anything (winter or all season) with an EU efficiency rating above a C that will fit.

Here's the EU label for the Nokian Hakkapeliitta R3s I'm driving on. I got mine through Discount Tire, so pretty easy to come by.

These labels are so informative the US should adopt them.

For fun I tracked down the EU label on my Goodyear Eagle F1 Asymmetric 3 summer tires:

Nice! Those are good - but pricey - tires! Tries to find some comparably sized but cheaper ones, naturally they are all back ordered. Ahh well. When the VikingContacts wear out maybe we can look for some of these again!

I’ve no experience with the Sumitomo tires but I remain very interested in the Michelin CrossClimate2 all-season tires. My weather is similar to yours apart from an occasional Nor’easter that will dump a foot or more of snow. I’m looking for all around performance with low rolling resistance. The reviews of the CrossClimate2 have been quite good. I hope to see my SE by mid-January. It appears to be waiting for a ship. Polyphonic may be able to add a few comments on the CC2 tires.
Click to expand...

On the CrossClimate 2 tires:
  • Jack of all trades: sure-footed in wet, dry, warm, and cold weather
  • Efficiency drop. The car's efficiency seems to be down 10-20% over the stock Ventus Evo 3.
  • Handling is OK, but a major step down from the summers (no surprise there)
  • Slightly less comfortable. I feel more of the road, with less cushion than the stock tires. More of an observation than a complaint.
  • Quieter. Somehow these seem quieter than the stock tires, except when digging into the accelerator pedal. You hear the tires squirm under load. Not a bad sound, but it's there.
  • Due to the last point I tend to accelerate slower. The stock tires were perfectly matched to squeeze out the awesome performance that the SE has on tap. CC2 is happier with a more chill driving style. They can still perform when needed.
  • Tread life is expected to be high (40k miles). I will be lucky if the stock tires hit 12k miles.
Overall, very happy still. For my use the car will be 100% capable in any weather and with the excellent tread wear reports they should last 5-6 seasons. I should note that this tire is being used as a winter tire on my car. As a year round tire: no way. It would sap too much of the fun from the car. Also keep in mind that my use case is primarily warmer weather of 40-60F**

I installed a set of those Conti VikingContact 7 tyres on Mike Wazowski (my Mini) (same size) and I am very happy with them - FAR better than the Michelin X-Ice tyres I had on my Honda (un)Fit. I did go with steel wheels because ultimately, they were lighter than the replica alloy wheels saving me some unstrung weight and about $1000.

I'm curious about which wheels you compared and what their respective weights are. Can you share those details?

What didn't you like about the X-ICE? Mine have been great and the TireRack testing has them at almost identical performance with the X-ICE coming out a bit ahead on ice performance and general (subjective) handling and ride quality

From my research, the Vikings are considerably more efficiency than the XICEs. And they are cheaper too :)

They don’t have the same snow/ice performance as the XICE, to be sure, but here in Ohio, that’s not as big of a deal as it would be if we were in, say, Montana.

Just curious, where did you find efficiency info?

All I could find was the EU tire label and both the VikingContact and X-ICE SNOW got a "C".

From my limited number of drives so far, the X-ICE Snow is actually more efficient than the BFG comp 2 A/S+ tires I had on... I guess that just shows just how inefficient the Comp 2s are haha

Now that the MINI app added the odo reading to the charging history, I really want to start a thread or shared Google sheet for people to add their average efficiency for different tire options. I just haven't figured out how to normalize the data for different city/highway mix... Not sure if that's even possible without more detailed logging.

The Michelin X-Ice Snow is not the same tyre as the X-Ice I had on the Honda Fit. As tested by Tire Rack, the tread width is not the same as those on the smaller and lighter car. Mine did not clear snow particularly well and had fewer longitudinal grooves that did not help. I would also note that Michelin realized they needed to improve the tread hence the addition of “Snow” to their product naming.
I have used Blizzaks in the past and they have been very good performance snow tires.
I chose the VikingContact 7s because of some previous experience with their summer tires and some advice from my trusted supplier (having bought at least 2 dozen sets of tires from them over the years).
Also know this. Eastern Ontario, where I live and drive daily) typically gets over 8 feet of snow over the course of the winter - from the light powdery stuff to the mashed potatoes. Temperatures get down to -30 ° C and occasionally lower. Thaws and freezing rain are also very typical.
Last but not least, there have been some supply chain issues - selection and availability for some sizes and makes have been a challenge.
