EV Tires Education - Performance vs. Efficiency (by Motortrend)

[DadzBoyz]

While this article doesn’t provide tire recommendations, it was a good education on EV tire make-ups and trade-offs.

If you aren’t in the tire business, many of the facts shared will be counterintuitive. Definitely worth a 5-10 minute read.

I had my OEM 225 Primacys on my 2021 MME4x through the first 18k miles. Because tire options are so limited on the OEM premium wheels, I switched to 20" wheels, and a new tire size of 255/45/20 with Michelin Sport all season 4's by recommendation of the local Discount Tire. My summer range went from 270 to 230-240.

There are a ton of factors as this article described, but the lack of EV-minded tires within specific sizes is also a contributing factor to some choices being made.

Interesting article. It seems to imply that range decreases as the tire wears down. Am I reading it correctly? I have 45k miles on my set and range seems higher than this time last year. I think last summer I was seeing around 270-275 estimated range and now I am seeing 285-290 most mornings.

I will be installing a new set of tires first week of Sept most likely so I will see what difference a new set makes on the estimated range.

Thank you. I like it too, but 90% of those that comment about it in the wild have no idea what it means. Then I explain it. Then I feel like an idiot for having to explain it. So, when it comes time for renewal I might change it up. We'll see.

I get it. Even a highly educated friend who has a Tesla and a Volt didn't know what an ICE car was! ?

To sum up that article, when you replace your tires, always start your search for a tire with an eco-focus rating of some sort. Many brands have product offerings with a low rolling resistance, which is the ultimate goal.

Read an article about Pirelli p-zero Elect all season tires coming soon (or maybe already on BMW iX?). Has anyone tried the winter ones? They seem spendy. I survived a Minnesota winter with the OEM A/S tires just fine—didn't drive through a blizzard to be fair, but didn't have any snow/ice issues on plowed roads either, or anything that I noticed more than my old ICE SUV.

Getting 3.1~3.4 combined freeway and city. The city is not impacted. Freeway took the hit from stock drag at high speed .
20” rim 9”wide. 245/45’s.
All season

Good article - thanks for sharing.

I'd really like to see a specific rolling resistance number on tires. That way, I know exactly the tradeoff of going to a wider tire or differences between models and brands.

As a rule of thumb, it looks like you lose ~7% range per wheel inch. (Engineering Explained, TFL, Tesla range docs and other tests seem to show about the same result)

Of course 2.4% of that loss is due to changing tire size.

And also rated for the weight of the EV.

Loss of 40 miles But look at that sexy ass beast!

Who's ultimate goal? Mine is max traction.
