# Skateboard wheel sizes: diameter 50–60 mm by use and deck width, the 608 bearing (8 × 22 × 7 mm) and two bearings per wheel

> What diameter are skateboard wheels, and what bearing do they use?

- Category: Hardware › Casters & wheels
- Kind: Standard part
- Basis: Three retailer guides (SkatePro, size-charts.com, Warehouse Skateboards) for diameter by use; the bearing envelope is the 608 page on this site (ISO 15); numbers only

## Notes

- Skateboard wheels run from about 50 to 60 mm for street, park and cruising and 60 mm and up for longboard and downhill; the retailers' ranges overlap but do not agree, so the table keeps each source's numbers (for example, cruising is 56–60 mm in SkatePro and 54–60 mm in size-charts.com; street is 50–53 in SkatePro and 50–52 in size-charts.com). The size-charts.com deck table maps deck width to a wheel range (7.5 in deck 50–52 mm up to a 9.0 in deck 54–60 mm).
- Every skateboard wheel holds two bearings, one in each side of the hub, and the bearing is the 608: 8 mm bore, 22 mm outer diameter, 7 mm wide (ISO 15; shielded ZZ and sealed 2RS share the envelope). Press-fit seat sizes and the 7 mm bearing width are on the 608 page. A spacer between the bearings is common but its length is not a standard dimension in any source read.
- Not published in the sources read, so not listed: wheel width, contact patch, hub (seat) depth, core design and wheel weight. Product titles use values such as '36.5 mm CP', but the guides do not define 'CP', so they are not used. Durometer (78A to 101A) is a hardness, not a dimension; not tabulated.
- No files: the 608 bearing and pocket models are already on the 608 page; a wheel has no standard profile.
