BYD SEAL Wheel Fitment Guide
This guide summarizes 19-inch wheel fitment for the BYD SEAL using factory specifications, measured fender clearance and two documented vehicle installations.
Factory Wheel & Tire Specifications
| Item | Factory Specification |
|---|---|
| Wheel | 19×8J ET45 |
| Tire | 235/45R19 |
| Gross Vehicle Weight Rating | 2,490kg |
| Factory Wheel Load Marking | 850kg per wheel |
Based on the vehicle's gross weight rating with a 1.2 safety factor, Makstton recommends a replacement-wheel load rating of at least 747kg per wheel.
Measured Factory Fender Clearance
The measured distances from the outer tire edge to the fender on both sides of the vehicle were:
| Position | Side 1 | Side 2 |
|---|---|---|
| Front | 10mm | 15mm |
| Rear | 20mm | 16mm |
Body tolerances, suspension height and actual tire width may affect the final position. These measurements are provided for reference only.
MAKSTTON Recommended 19-Inch Custom Fitment
| Position | Wheel | Recommended Tire | Expected Result |
|---|---|---|---|
| Front | 19×8.5J ET42 | 245/45R19 | Approximately flush with the fender |
| Rear | 19×8.5J ET36 | 245/45R19 | Approximately flush with the fender |
For daily use, Makstton recommends pairing an 8.5J wheel with a 245-width tire to provide better protection for the wheel edge.
18-Inch Fitment Reference
An 18-inch setup can follow the same wheel-position logic. The vehicle's basic chassis geometry does not change with wheel diameter, but brake clearance, overall tire diameter and actual tire width must still be confirmed before the final specifications are selected.
Real-World Fitment 01: BYD SEAL
| Item | Front | Rear |
|---|---|---|
| Model | MAKSTTON MR7MONO | |
| Construction | Die-Forged | |
| Wheel | 19×8.5J ET42 | 19×8.5J ET35 |
| Tire | 245/45R19 | 245/45R19 |
| Suspension | Lowered | |
This setup is close to Makstton's standard custom recommendation. The 245/45R19 tires provide additional wheel-edge protection while retaining a full front and rear stance.
Real-World Fitment 02: BYD SEAL
| Item | Front | Rear |
|---|---|---|
| Model | MAKSTTON FG FK07R | |
| Construction | Custom Forged | |
| Wheel | 19×9J ET43 | 19×9J ET38 |
| Tire | 235/45R19 | 235/45R19 |
| Suspension | Lowered | |
The 9J wheel width gives this vehicle a more aggressive outer position. Because the suspension has been lowered, the upper tire position sits further inward than it would at the factory ride height.
Both documented vehicles use lowered suspension. In particular, the second setup would sit noticeably further outward at the factory ride height. Do not apply these specifications without considering the vehicle's suspension height, alignment and actual tire width.
Fitment Notes
Wheel fitment is not one fixed answer. Wheel width, offset, actual tire width, suspension height and the desired stance all affect the final result.
The data in this guide is based on physical measurements and documented installations. Body tolerances, suspension height, actual tire width and individual vehicle configuration may still affect the final position.
