Function over Form - Best wheels for pure efficiency that support the Mach-E?

[dbsb3233]

Another thought is to simply overinflate your existing tires. They recommend 39 PSI on the Michelin Primacy's that usually come on the Mach-E, but many of ours were delivered with closer to 45 PSI. Not sure if they did that purposely to expand the range, but it should (slightly).

But it also makes the ride a bit harder.

Here is an interesting comparison of a Model Y with both the stock 19” wheels and tires along with the 18” wheels and tires from the model 3. Watch video
Interesting results is that there was no efficiency improvement despite the smaller, lighter, more narrow tire.

Higher pressure also reduces the already low amount of grip provided by the Primacys. These tires inspire no confidence whatsoever so higher pressure carries more negatives than a slight range benefit.

Yeah I don't like it either. I do pump mine up to about 41 for road trips on smooth interstates, but then down to 35-37 around home on crappy roads. Anything to try and mitigate the jarring ride on poor roads.

So far I've had no problem with grip (in fact it grips better than any car I've owned). But I drive it more like a luxury car than a sports car.

That is because aerodynamics matter more than weight. I didn't watch the video because I couldn't get past the ads, but I assume both wheels are similarly aerodynamic. The other big factor is rolling resistance, and both wheels with stock Tesla tires have low rolling resistance tires. Therefore the results make perfect sense to me.

It seems that FastWheels do have a version of the EV01+ that supports the Mach-E! I am very tempted to buy them and see if there is a noticeable range improvement. In the YouTUbe video by Evo-lution, he managed to increase his efficiency from 16-17kWh/100km to 13-14kWh/100km by using these wheels and aero covers on his Kia Niro with the exact same tires.

I'm not sure if the same efficiency gains could be made with my Mach-E but if I could save 2-3kWh/100km I would be incredibly happy!

Another option I found during some searching - OZ Racing's Superturismo AERO-E - available in a 19" and 20", wide range of widths and offsets, and it has inserts between the spokes as well as a nice flat cover for the hub. Dimpled for improve aerodynamics, apparently.

I don't know if it is available in our drilling or hub bore, but it is likely to be possible as a special order, need to reach out to them. If their similar Superturismo line is any indication, cost for 20" rims would probably be in the $650-750 each zone.

EDIT: TireRack appears to the the main US dealer for OZ, I just sent an inquiry to see if they are available in our drilling and offset range. Will update when I hear back.

Interesting, they are pretty much molded inserts for their wheels … curious.

Given the Lucid has the most range, does anyone know who makes those wheels and if they are available in MME sizes?

You’d be better off buying Volvo C40 wheels. Since those will already fit.

It seems like the EV01+ only come in 19”x7.5” or 19”x8.5” and that doesn’t appear to match the width of the stock Michelin Primacy tires which is 7”.

I would like to find options for the stock tires as I feel like going with wider tires would offset any gains in range I would have gotten from the new wheels.

You can run OEM 225/55 tires on 19x7.5” wheels easily, I’d probably stay away from the 8.5” width if you’re really set on the OEM tire size. The extra width just adds weight and if you want 225s there’s just no need.

Oh really? Maybe I’m misunderstanding how the wheel sizes work. How does that work if the wheel is wider than the tire? Wouldn’t that stress the tire?

No, tire width doesn’t match wheel width, however, there are acceptable ranges of wheel widths that tire manufacturers spec for a given tire section width. Example: the OEM 225/55-19 tires work with wheels from 6-8” wide per Michelin specs on the TireRack site:

This is fantastic! It allows me to actually consider the EV01+ now, thanks for the info!
From what I have seen online, the EV01+ seems to be one of the more efficient wheels available for EVs
