EVs Demand More
From Your Rims
An electric vehicle is not just a petrol car with a different engine. The weight, torque delivery, and braking behaviour are fundamentally different — and your rims need to be spec'd accordingly.
Load Index — The Critical Number
EVs are significantly heavier than equivalent ICE cars due to battery packs. The BYD Sealion 7, for example, weighs around 2,200kg kerb — that's 400–600kg more than most petrol SUVs. A standard rim with an insufficient load index will deform or crack under sustained EV weight. Every Gravity EV rim is rated for high-load applications.
Instant Torque & Rim Stress
EVs deliver 100% of torque instantly from 0 RPM. On a petrol car, torque builds gradually — rims experience progressively increasing stress. On an EV, that full rotational force hits the rim the moment you press the accelerator. Low-quality cast rims can develop micro-fractures under repeated EV-style acceleration. Forged construction handles this far better.
Regenerative Braking & Brake Dust
Regenerative braking means EV friction brakes are used far less frequently — but when they are used (emergency stops, high-speed deceleration), they work extremely hard. Less frequent use also means brake rotors can corrode faster. An upgraded BBK like AP Racing keeps the system sharp and ready, and reduces uneven pad glazing from infrequent use.
Wheel Weight & Range
Every gram of unsprung weight affects EV range and ride comfort. A heavier rim forces the motor to work harder, particularly at highway speeds. Forged rims are typically 20–30% lighter than equivalent cast rims at the same strength — which is why EV manufacturers like Tesla spec forged wheels on performance variants. Gravity EV rims follow the same principle.

What We Check
Before Every EV Fitment
Every EV rim fitment at Pitstop goes through a structured check. Not because it's required — because it's the only way to do it properly.
Load Index Verification
We verify the rated load index of every rim against your EV's actual kerb weight — axle by axle. EVs often have different front/rear weight distribution due to motor and battery placement.
PCD & Offset Fitment Check
Incorrect offset on an EV creates unusual tyre scrub and stresses wheel bearings faster — particularly an issue given EV torque delivery. We confirm PCD, offset, and hub bore before any rim goes on.
Torque & TPMS Reset During Fitment
All rims are torqued to manufacturer spec with a calibrated torque wrench during the fitment process. TPMS sensors are reset or replaced as part of the same job — critical for EVs that display real-time tyre pressure in the instrument cluster.
Hub Bore — Perfect Fit, No Rings Needed
Generic aftermarket rims use an oversized hub bore and rely on plastic hub rings to centre the rim on your car's hub. Over time these rings can crack or go missing, causing vibration. Gravity EV rims are machined to your car's exact hub bore diameter — a direct, rattle-free fit with no centric rings required.
Common Questions
Straight answers for EV owners in Singapore.
Technically yes, but it depends on the load index. Most aftermarket rims are rated for petrol car weights — typically 1,400–1,800kg. Popular EVs in Singapore like the BYD Sealion 7 (~2,200kg), Tesla Model Y (~2,000kg), and Hyundai IONIQ 5 (~2,100kg) exceed what standard rims are rated for. A rim that’s underrated won’t necessarily fail immediately, but it will fatigue faster and is more likely to crack on Singapore’s speed bumps and kerbs. Gravity EV rims are high-load rated specifically for this.
Yes, but the impact depends on what you’re upgrading to. Going from OEM to a heavier cast rim of the same size will reduce range slightly due to increased rotational mass. Going to a larger diameter but lighter forged rim can be range-neutral or even a small improvement if the overall weight is lower. The bigger factor is tyre selection — a lower-profile tyre on a larger rim typically has higher rolling resistance, which affects range more than the rim itself. We can advise on the right tyre pairing for your specific EV model.
The BYD Sealion 7 has a kerb weight of approximately 2,200kg with an uneven front/rear weight distribution due to its rear motor configuration. As a rule of thumb, each rim should be rated for at least 650kg to handle the heaviest axle load safely. Gravity EV rims exceed this. WhatsApp us your car model and we’ll confirm the exact spec.
Not mandatory, but recommended. EV-specific tyres (marked “EV” or “Elect” by brands like Michelin, Hankook, and Bridgestone) are engineered with reinforced sidewalls for EV weight, lower rolling resistance for range efficiency, and foam inserts that reduce road noise. We carry EV-rated tyres and can package them with your rim order.
Changing rims alone does not void your EV warranty in Singapore. Under LTA regulations, rim modifications within approved size parameters are permitted for road use. Your vehicle warranty covers manufacturing defects — a rim change doesn’t affect that. However, if an incorrectly-specced rim causes damage to suspension or wheel bearings, that damage would not be covered. This is exactly why correct load index and offset matter so much for EVs.
Yes — we’ve done it. The BYD Sealion 7 on this page is the first in Singapore to receive an AP Racing Big Brake Kit front and rear, alongside coilovers and Gravity rims. AP Racing BBK fitment on EVs requires at least a 19” rim to clear the larger caliper. WhatsApp us your car model and current rim size and we’ll confirm compatibility straight away.
