MAKSTTON Vehicle Fitment Guide

BYD SEAL Wheel Fitment Guide

By Binghua Yang · September 2026

Based on MAKSTTON's vehicle measurements, factory specifications and verified installations, this BYD SEAL wheel fitment guide brings together the key data for the model: wheel sizes, PCD, center bore, ET, tire specifications and fender clearance.

The BYD SEAL uses a 5×120 PCD and a 64.1mm published center bore, and comes from the factory with 18×7J ET45 wheels and 225/50R18 tires. When MAKSTTON machines custom wheels for this model, the center bore is cut to 64.05mm.

This guide also collects several real-world installation cases, including wheel setups on lowered suspension, and explains how different ET values and wheel widths shift the wheel position, to help owners choose aftermarket wheels.

Factory Wheel and Tire Specifications

MAKSTTON recorded two factory wheel-and-tire configurations on the BYD SEAL. The front and rear use the same wheel and tire size within each configuration.

Factory Setup Position Wheel Tire
Standard 18-inch Front 18×7J ET45 225/50R18
Rear 18×7J ET45 225/50R18
Standard 19-inch Front 19×8J ET45 235/45R19
Rear 19×8J ET45 235/45R19

Bolt Pattern and Center Bore

Specification MAKSTTON Reference
Bolt Pattern (PCD) 5×120
Published Center Bore 64.1mm
MAKSTTON Recommended Custom Wheel Center Bore 64.05mm

The published figure is the center bore quoted for the factory wheel. For a MAKSTTON custom wheel on this application, MAKSTTON specifies a center bore of 64.05mm so the wheel locates directly on the hub without an adapter ring.

Confirm the fastener seat type and thread engagement on the actual vehicle before the final installation.

Measured Factory Fender Clearance

Baseline: factory 18×7J ET45 package at factory suspension height, measured from the fender lip to the outer wheel rim.

Measurement Front Left Front Right Rear Left Rear Right
Fender lip to wheel rim ≈23mm ≈24mm ≈34mm ≈31mm

Use this guide as a baseline, not the final answer. Measurements from your own vehicle are always more valuable. Read our Flush Fitment Guide, measure your car, and calculate the fitment that matches the stance you want.

Fender clearance may vary slightly between vehicles due to production tolerances. Use these figures as a reference only.

Recommended MAKSTTON Wheel Designs

These MAKSTTON wheels are available in forged (FG) and flow-formed (FF) constructions, and can be produced in the recommended 19-inch BYD SEAL specifications with the correct load rating, PCD and center bore for this vehicle.

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 run lowered suspension, so confirm ride height before applying these specifications.

BYD SEAL Wheel Fitment FAQ

What is the BYD SEAL bolt pattern and center bore?

The bolt pattern is 5×120. The published center-bore specification for the factory wheel is 64.1mm, while MAKSTTON machines its custom wheels to 64.05mm for this application.

What is the factory BYD SEAL wheel and tire size?

The measured BYD SEAL runs a 18×7J ET45 wheel with a 225/50R18 tire.

What 19-inch fitment does MAKSTTON recommend for the BYD SEAL?

See the final recommendation table for the current wheel-rim inset options, offsets and matching tire sizes.

What load rating does a BYD SEAL wheel need?

The BYD SEAL factory wheel carries a marked load rating of 775kg per wheel. Confirm that any replacement wheel is rated at or above the load marking of the wheel it replaces, and check the rating against the vehicle’s actual configuration before ordering.

Will an 18-inch wheel fit the BYD SEAL?

Yes, an 18-inch setup follows the same wheel-position logic because the chassis geometry does not change with wheel diameter. Brake clearance, overall tire diameter and actual tire width must still be confirmed before the final specification is chosen.

Can these BYD SEAL fitments be used on a lowered car?

Both documented installations in this guide run lowered suspension, so the offsets above already account for a lower ride height. Because suspension height, alignment and actual tire width change the final position, confirm clearance on the actual vehicle before ordering.
