How do you tell if your roller skate wheels are indoor/outdoor or indoor only?

The pair I have are like Sketcher 4wheelers (But Not).


The brand name of these skates is worn off and theres nothing on the wheels or bottom of the skates. Only thing I could find is the size tag on the tongue of the skates.


The wheels seem to be of tough rubber material.

How do you tell if your roller skate wheels are indoor/outdoor or indoor only?
Usually, outdoor wheels are much softer and rounder on the edges. Indoor wheels are a little firmer and wider. Really it doesn't matter what you use indoors, the firmness is up to you. Some people prefer outdoor wheels indoors if their skating surface is slick. However, you want to use the softer wheels outdoors to avoid being tripped by a piece of gravel or a crack in the pavement.
Reply:The hardness of the wheels will let you know if they're indoor or outdoor wheels. Outdoor wheels are squishier than indoor. You can use indoor wheels outside if they're soft enough, but they'll catch on any debris you roll over.





The ABEC 1 you found is the rating of the bearings inside the wheels, not actually part of the wheel itself.
Reply:All I can help you with is the ABEC-1 which refers to the wheel's bearing. This information was helpful to me when I was looking for skate information: www.lowpriceskates.com





This is from that site:





ABEC RATINGS - The ABEC (Annular Bearing Engineering Council) rating system is neither a mandatory testing method for manufactured bearings, nor is the claimed rating subject to certification or verified by any regulating agency as being true!





In short, ABEC ratings can be misleading. So is the apparent international recognition of the "Council" (Please see ISO and DIN agencies by searching the Internet through those keywords). Be careful when choosing the bearings that are best for you. Feel free to call us at 1.877.277.2346 to find the best bearing for you. We'd be happy to discuss it with you.





Although NO materials criteria are specified by the ABEC, the rating system is based on the old (Tried and True) level of "noise" or "rumble" detected at higher revolutions in the testing procedure. The logic in this testing procedure is that if the bearing can be "heard" then the noise is an expression of "friction". Friction then, impedes the free rotation of the bearing. The more the noise heard from a spinning bearing, the LOWER the rating. The less noise heard from a high-speed test bearing, the HIGHER the rating. ABEC ratings are 1, 3, 5, 7, and 9.
