Do Wheel Covers Actually Improve Range? Real-World Testing, Aerodynamics & More

01 / Let’s Get to the Point: Do They Really Work?

Yes. Wheel covers like HALODISC 2 absolutely help with range—
especially at cruising speeds above 37 mph, where aerodynamic drag becomes your EV’s biggest enemy.

In our field tests, we observed:

• Cleaner airflow around the wheel wells (verified via CFD simulation)

• Average energy savings of about 7% at highway speeds

• No noticeable increase in wind noise—in fact, it even felt slightly quieter

This isn’t a magic add-on that gives you 50 extra miles.
But it does help reclaim energy you'd otherwise waste battling turbulence—
so you can go farther, with less.

02 / The Principle Is Simple: Less Turbulence, More Efficiency

Your wheels are among the most airflow-disruptive parts of your vehicle.
Without a cover, air flows into the wheel cavity, gets trapped, swirls around, then gets forced out—wasting energy and creating unnecessary noise.

HALODISC 2 uses a sealed disc surface with a center-lock system to smooth that flow.

It doesn’t change your car’s body.
It just helps your wheels cut cleaner through air, the way they should have from the start.

03 / What We Tested — Real Roads, Real Numbers

Range Impact (Energy Efficiency)

We tested HALODISC 2 on a Tesla Model 3 Long Range, driving ~37 miles at a steady highway speed (50–68 mph):

• Without covers: average consumption ~260 Wh/mile

• With HALODISC 2: reduced to ~243 Wh/mile

• Net improvement: ~7% more efficient

Real-world test: public roads, no A/C, full charge, standard tire pressure.

Not a lab test. No ideal wind tunnel. Just real driving—like yours.

04 / So, Is It Worth It?

We're not promising miracles—or selling you on fear.
But if you drive highways regularly, or care about optimizing your EV’s every detail,
HALODISC 2 Custom Numbers is a smart, subtle upgrade that delivers.

No apps. No software. No range anxiety gimmicks.
Just clean design, functional benefit, and a bit more peace of mind per mile.

💬 FAQ: What Most Owners Want to Know

Q1: Does it only help at higher speeds?
Yes—mainly above 37 mph. At city speeds, the benefit is smaller, but it still helps reduce wheel turbulence and noise.

Q2: Will all Teslas see the same improvement?
Not quite. The more open your wheel wells, the greater the effect. Model 3 and Model Y benefit the most.

Q3: Do wind and weather affect results?
Yes, wind direction can amplify or reduce gains. But aerodynamic optimization always helps, even with variable conditions.

Q4: Will it stay secure long-term?
Absolutely. HALODISC 2 uses a motorsport-grade center-lock system and includes a dedicated tool.
It’s been field-tested under real driving conditions—with zero rattle, zero looseness, zero drop-offs.
