Airless scooter tire

Buy offer Details

Dear Sir/Madam,
I am looking for a new wheel to replace the current wheel that we use on our product. We are currently using an air filled tire and would like to switch to an airless tire that is flat free/ puncture proof. We will order 2,000/ year meaning that we will purchase 500/quarter.
Im looking for products with the following specifications :
Wheel Diameter : 200mm
Wheel Width : 50mm
Color : Black/ Grey
Cost : <$10/tire
Load : 30-70KG
Mass : <1 KG
Mounting Hardware : M10x75 FHCS or similar
Bearing size : 10mm ID x 28mm OD x 8mm
Certification : ROHS
Images show our current tire. We would like to stick to this but use a solid tire that is not air filled.
THANK YOU!
