Fitment and installation

ENGWE Engine Pro is only a fitment candidate based on the nominal 20 × 4.0 size. Fitment of this exact tyre is not confirmed. A technician must compare the complete old tyre marking, bead-seat diameter and profile, permitted rim width, and fork/frame/mudguard clearance. Required load and speed ratings must be confirmed; those markings on the supplied tyre have not yet been reliably verified.

Confirm use with a suitable inner tube. Approval for tubeless use is not confirmed. Follow the rotation direction and 20 PSI limit; do not transfer a higher pressure from the old tyre.
