Found these on Yahoo Auctions or Mercari Japan?

We bid, buy and inspect the wheels and tyres in Japan, then ship them worldwide. Get an instant landed-cost estimate, then let us buy them for you.

Weight is per boxed item — one 18" wheel+tyre is roughly 20 kg. A full set is quoted consolidated; ask us for an exact price.

No proper box? Loose or poorly-packed wheels may need repacking into a carton for safe international shipping — a packaging fee (from ¥1,000) may apply. We always tell you before we ship.

Figures are geometric estimates for comparison — confirm load rating, brake and arch clearance before purchase. Shipping is a live estimate; the exact price is confirmed for your postcode and packed weight at checkout.
