I shipped out my old zenki 16" oem SE 5 spokes twisted wheels. Weight was 22 pounds each at UPS.
Cost was like $60 for the full set to Tennessee.
Oem wheels for a lil car cant weigh anymore than 30 pounds, i dont believe it.

If the guy says shipping is $120, then fine, its 120. EBay have alot of those stuff. Item cost like $5, but the shippping is like $50.
