Hi,

I have a few thousand wheels that I want to list, but there is no category for wheels or tires(tyres)

Should be Cars & Vehicles/Wheels/(then diameters)
Cars & Vehicles/Wheels/14"
Cars & Vehicles/Wheels/15"
Cars & Vehicles/Wheels/16"
Cars & Vehicles/Wheels/17"
Cars & Vehicles/Wheels/18"
Cars & Vehicles/Wheels/19"
Cars & Vehicles/Wheels/20"
Cars & Vehicles/Wheels/21"
Cars & Vehicles/Wheels/22"
Cars & Vehicles/Wheels/23"
Cars & Vehicles/Wheels/24"

More Categories or search options and item specifics are necessary, but if you could set these categories up it would be a great help and I could start listing my inventory.

Thanks,
Chuck Larocco
