Aftermarket wheels on EV?

You won't loose much range going to a less aero wheel, maybe in the 2% range, your tire choice may have a bigger effect of range but again not hugely so. Don't go smaller than the stock 17 inches as smaller rims may not clear the rear parking brake hardware. Also keep sensitive to your wheel offset for your new wheels. Stock Kona EV has a + 50mm offset I would not go any less than + 40-45mm. My winter wheels sit at +42 mm as a consequence the tire sits visibly proud of the wheel well and keeps my car dirty. You may also get adverse handling characteristic if the offset difference is too severe.

Stock halogens could be better, most people who have done the LED swab find an improvement. I really like my HID swap and would do it again.

Your 2020 Kona in Canada will only have a onboard charger that can support 32 amps at 240V or approximately 7.6 Kwh. The higher rating is for countries with residential 3 phase service.

 

What model did you order and which country. Hyundai has different features in different geographic areas and different models. The Ultimate comes with LED headlight which I'm not sure you can swap for high powered Halogen lights. Huge current difference. The IIHS rated the Kona's LED a good rating in the headlight rating https://www.iihs.org/ratings/vehicle/hyundai/kona-4-door-suv/2019#headlights.
Larger tires may change the headlight aiming and may impact your control of the Lane Keeping Assistant (LKA) system. With stock tires, my Ultimate's LKA helps but doesn't work well on high degree of curves. Wider tires may affect this as well.

 

I went with 55W 5000k HIDs , nice BMW white and bright. Honestly a huge improvement over the stock low beam yellow halogens and subjectively brighter than any LEDs I have seen. High beams are still stock halogen, there wasn't a suitable HID bulb adapter available for the high beams. At least that is what my installer claimed. I think the situation is the same for the LED high beam conversion, I could be wrong or that may have changed.
I did lower the beam pattern a little and have not annoyed anyone in the past 6 months.

This a video of the low beam HIDs on my Kona

I think the trend regarding that subject will be set by Rivian, Bollinger, the Cybertruck and Ford. The Rivian is 11 kW and I'm assuming that's single phase given the North American-centric target market. So if you can go higher within your budget, it can't hurt.

For passenger cars I would be surprised if single phase 230-240 VAC charging ever exceeds 32-35 amps, simply due to the size and cost of the on-board hardware required, and that it would push the bounds of worldwide domestic electricity feeds outside of N-A. The king of the hill in that regard was the (now out of production) Renault Zoe Q90 which used electromagnetic trickery to attain an amazing 43 kW from a 63 amp 3-ph supply.

 

nice wheels!!

 

Yeah, I think the more chunky thicker spoke wheels like this suit the car better than the more commonly-chosen thin spoke types.

 

We did what you're saying - though we put the winter tires on new alloy wheels, because it saved money to just order the snows pre-mounted and balanced on the new rims. The range difference isn't really noticeable. When I swapped in the spring, I didn't see the energy efficiency change. Could be a couple percent though - I wouldn't notice that.

I did the LED conversion and I'm glad I did. $50, I think, and it looks much better, and is brighter.

The Kona charges at 7.2kw max on Level 2 charging equipment. For your EVSE, I'd check out how big of a circuit you can add to your current electrical service. If you can add a 50A circuit, get a 40A EVSE. If you can add a 70A breaker, then you could go up to a 50A EVSE, for future-proofing. Perhaps a good idea if you know you'll be in your home for a while, but it will certainly cost more for the electrical work, so you need to decide how much that's worth it to you. Personally, I don't think being able to charge a car faster than 7.2 kw at home is much of an advantage, since 7.2 will fill even a long-range car overnight. What's the difference if it's done at 2 am instead of 4 am?
