  1. TL;DR: wheel size and tire choice can make a substantial difference in EV range, e.g.:

    > The BMW i4 M50, for example, a souped-up version of the marque’s newest electric sedan, travels 271 miles on a full charge with its standard 19-inch performance tires. On high-performance 20-inch wheels, however, it makes only 227 miles — a 16% handicap.

    Customer choose style and performance over range–although the article fails to mention that often bigger wheels come with the higher level trims, so if you want (say) more safety features, you have to take the bigger wheels as well.

  2. It’s not a conundrum. Manufacturers need to stop being dumb and offer smaller wheels on the higher trim levels, and actually market the benifits.

    Manufacturers could easily bring about this culture change. Pink use to be a boys colour, now that’s blue, and pink is for girls.

    In the short term yeah sure you might get some push back, buy just make both options.

    Eventually when the customer notices “Hey, how come I get an extra 20% range with the smaller wheels” then watch how quickly they’ll change your preferences. Consumers can only really communicate with corporations via binary choices. They either buy a product or they don’t. It’s up to the company to offer the products. Consumers can’t demand something that isn’t offered in the market.

  3. It’s not a tire conundrum. It’s a visual appearance preference. When I ordered a model Y, I had the option to pay $1000 or $1500 for larger, tires that would use more energy, or to save money and get more range. There’s a reason Tesla is offering the larger tires, and it’s because the consumer seems to want it.

  4. It’s wild to me that nobody cares about efficiency, and hasn’t, for a long time. Where’s the article about how choosing the larger wheels for your ICE car makes it burn 7.5% more gas?

    Burning gas is terrible, and we should do everything we can to minimize how much of it we do. But people only care about range, not efficiency, which is why it’s EVs that get better aerodynamic designs and LRR tires, not ICE cars.

    Sorry, but writing like this annoys me. The author is using “wheels” and “tires’ interchangeably as if they were the same thing.

    Looking at the actual specs, the M50 uses a staggered 245/40 and 255/40 for the 19″ wheels, and a whopping 255/35 and 285/30 for the 20” set.

    The big question I have is how much of the range loss is from the additional rotational mass (larger diameter wheels) versus the additional overall width (wider tires). And, unfortunately, the article makes no attempt to address that.

  6. Yeah, my model 3 is only a couple hundred pounds heavier then comparable cars…

    Not that big a deal.

    Massive torque however fries tires.

    Mines set on chill. Tires will last a lot longer.

  7. I switched my Tesla Model S Long Range Plus from its OEM tires to Yokohama summer tires and lost something like 8 to 10 percent range. That in itself wouldn’t have been so bad, but what really hurt was that it threw all the navigation estimates off. My projected state-of-charge on arrival would gradually drop as I drove down the road, and this got me in trouble.

    I recently switched to Pirelli all-season “Elect” tires and regained that lost range. Tesla also updated the nav system at the same time to better account for weather, and now the projections are super dependable.

    I have the 19-inch wheels with the plastic aero covers that so many online commenters say are hideous. (I’ve never heard anybody say they look bad when looking at them in-person, tho!) Anyhow beauty is in the eye of the beholder, and they don’t bother me at all. I think 21-inch wheels look a bit goofy, to be honest, and I’m surprised and puzzled that so many people choose them.

  8. I took a about a 15-20% hit on my pickup going with a slightly larger tire. This affects all vehicles it’s just ICE vehicles hold a lot of energy and refill quicker. That’s all. There is nothing to see here.

  9. With the Accord hybrid going to the 19” wheels in the Sport trim vs 17” in the base or EXL brings you down 5mpg. Buyers just need to figure out what they really want more: style/grip or economy/comfort.

  10. I hate this slow migration toward monster wheels. I finally ordered a Model Y and opted for the smaller 19” wheels. Hopefully when it arrives I can sell those and get some 18s instead. I’d like to go as small as possible without hitting the brakes or suspension.

  11. I guess it’s just fortunate that range is no where near the problem that fossil drivers think it is. Being able to drive for 3hrs 10 mins before a break with cool wheels or 3 hrs 22 mins before a break with less cool wheels..meh

  12. IDK who really cares if fancy tires reduce range a bit, we’re paying the cost now in kWh instead of litres of gasoline, EVs are just so much more carbon and cost efficient to begin with.

  13. As long as you have ‘enough’ range, who cares? I got 18″ Audi A6 wider rims on my eGolf, and the range hit is minimal, but the performance is night and day better than the 16″ pizza cutter eco tires. I still get through my day just fine.

    So, this sounds like another non-issue to me. Making news from nothing.

  14. It’s the same for every car.
    Just in an EV everyone is focused on initial potential range…🤦‍♂️ All just cause it displays this very accurately.

    It’s like running an ICE with 25L petrol. That will awake more people on their car consumption.
