LFI EV Efficiency Feature · Tesla Model 3
Two Tesla Model 3 owners went from stock 19-inch wheels to LFI CSF6 18-inch forged wheels and reported up to 10% more range. The win was not magic. It was weight, tyre choice, and sidewall finally working together.
Going 18-inch helps only when it lets you run a lighter wheel, a more sensible tyre, and enough sidewall for the car to stop crashing over every sharp edge. Just bolting on any 18-inch wheel will not automatically give you range.
Lower rotating mass.
The CSF6 removes weight where the motor actually has to spin it.
Real sidewall.
A 235/45R18 gives the Model 3 more tyre to work with, so the ride gets calmer without making the car feel lazy.
Correct tyre choice.
A low rolling-resistance touring tyre makes the setup work. A sticky track tyre throws most of the gain away.
| Setup | Wheel Weight | Delta vs CSF6 | What It Means |
|---|---|---|---|
| LFI CSF6 forged 18x8.5 | Approx. 7.7 kg | Baseline | Light forged wheel built around a clean Model 3 daily setup. |
| Tesla Model 3 19-inch Sport wheel | Approx. 11.34 kg / 25 lb | +3.64 kg per corner / +14.56 kg per set | More rotating mass and less tyre sidewall before you even discuss tyre model. |
Fourteen kilos in the boot is just payload. Fourteen kilos taken off the wheels is different. The suspension has less mass to control, and the motor has less inertia to spin every time the car pulls away.
Less unsprung mass lets the wheel follow the road more cleanly. That is why owners often notice comfort and composure before they even start calculating range.
In city driving, the car keeps accelerating and decelerating. A lighter wheel-and-tyre package reduces the work needed each time. Small gains repeat all day.
The 235/45R18 tyre gives useful rubber between rim and road. That helps ride quality, pothole tolerance, and daily EV comfort.
Range-focused wheel with the wrong tyre is like ordering kopi kosong and adding condensed milk after. The tyre is not a footnote; it is half the result.
This owner was not chasing a show stance. The goal was range, comfort, and fewer harsh hits from daily roads. The 18x8.5 ET38 CSF6 setup kept the car square, clean, and spacer-free while dropping real weight at each corner.
The Highland owner used the same formula because the logic did not change with the facelift. A lighter forged 18-inch wheel, a practical 235/45R18 tyre, and a clean square fitment still make sense for range-focused daily use.
| Factor | Why it matters | Practical note |
|---|---|---|
| Tyre rolling resistance | A sporty tyre can erase the saving from a lighter wheel. | Use an EV-friendly touring tyre if range is the goal. |
| Tyre pressure | Soft tyres drag and waste energy. | Check pressure regularly, not only when TPMS complains. |
| Alignment | Too much toe scrubs the tyre while rolling straight. | Align after wheel or tyre changes. |
| Speed and weather | High speed, AC load, rain, and heat can move range numbers hard. | Compare results on the same route and similar conditions. |

No. A heavy 18-inch wheel or the wrong tyre can perform worse than a good 19-inch setup. The weight and tyre package drive the result.
The CSF6 is approximately 7.7 kg. Tesla's 19-inch Sport wheel is commonly referenced at about 11.34 kg / 25 lb, so the wheel saving is roughly 3.64 kg per corner, before tyre differences.
No. It is customer feedback from two specific builds. Tyre model, pressure, alignment, speed, route, weather, and driving style all affect the final number.
Both builds used LFI CSF6 forged wheels in 18x8.5 ET38 square with 235/45R18 tyres.
The point is strength-to-weight ratio. A forged wheel lets LFI remove weight while keeping the structure suitable for EV torque, daily road use, and pothole reality.
Yes, but LFI should still confirm your model year, brake setup, tyre target, hub details, and use case before production.
