BackBYD SEAL is engineered as a sporty, high-efficiency electric sedan—so the OEM tire brief is never “just match the size.” It’s about balancing range, quiet cabin, high torque traction, and stable high-speed handling.
Across SEAL variants, common OE tire sizes include 235/45 R19 (often used on higher trims) and 225/50 R18 (common on other variants/markets).
Why BYD would choose Giti for SEAL (the technical “why”)
1) Load + torque-ready construction
EVs typically carry more mass than comparable ICE sedans, and they deliver instant torque—both of which increase stress on the tire’s casing, belts, and tread blocks. That’s why OE specs for SEAL include higher load/speed requirements like 95V / 99V in the Giti fitment listing.
For BYD, this means confident stability under acceleration, braking, and sustained highway speeds.
2) Quietness becomes a “first-class” requirement in EVs
With less powertrain noise, tire noise becomes more noticeable—so the OE program must control pattern noise and resonance. The GitiControl P10 (an ultra-high-performance tire line in the range) highlights optimized pattern block geometry for low noise and a smooth ride, and positions itself as delivering comfort and silence without compromising control and safety.
That’s exactly the kind of tuning an EV sedan program demands: refined NVH without losing steering precision.
3) Rolling resistance to protect range
Range is a headline metric for EV buyers, and rolling resistance is one of the most direct levers OEMs pull through tire selection. Competing OE approaches for BYD SEAL in the market explicitly emphasize energy-efficient OE fitments.
Giti’s own passenger-car technology messaging includes compounds and design approaches aimed at improving rolling resistance and energy efficiency (including notes on improved rolling resistance compounds and EU rolling resistance ratings in selected sizes).
4) Wet braking + safety validation as part of OE sign-off
For an OEM, the tire must pass a full validation program (wet/dry braking, handling, hydroplaning resistance, durability, noise/NVH, and high-speed endurance). Giti’s OEM fitment listing and product positioning in its catalog reflects tires designed to balance grip, comfort, and control—the core triangle of OE acceptance for an EV sedan.
Together, these engineering strengths make Giti a natural OEM partner for BYD SEAL—delivering the efficiency, control, refinement and validated performance required to support the next generation of electric mobility.
