Not indoor. This may sound weird but you want as much contact with the ground in as small area as possible. outdoor has a tendency to create tread on your wheels just from skating across asphalt which chews up your wheels. Remember tread helps your grip when torque is applied by the tread itself. in speed skating your wheels are not powering you therefore it is not helpful or necessary.

You can try a roller skatinng rink in you're area. Sometimes they have nice skates for sale. Sometimes they are used. I hope this answer helps!
Its the wheels that are different. Outdoor wheels do not have the grooves, which means you don't feel as many bumps outdoors. Indoor wheels have grooves, which helps you run smoother. If you wore indoor wheels outdoors, you would feel every little bump and pebble. Plus, outdoor terrain with indoor wheels wrecks the wheels.
No, tires have treads.
he found a pair of roller skates on which the wheels were arranged in a single row. While the skates felt slow and clumsy, they gave him the sense of skating on ice that traditional roller skates did not.
advancement in roller skates has changed dramatically. when roller skates were invented, they were something like this: a wooden plate resting on two sticks attached with wheels. as scince and technology changed, roller skates also strted to develope. around 1980's the new model of roller skates came out. this time it was much stable and quicker than the previous ones. those skates used ball bearings fitted in the wheels. the top was made of metal. these days they are more advanced. they still use ball bearings, metal top but added with a fluid, which allows to gain a quick and fast speed.
Vehicles such as cars, bicycles, and trucks have wheels for transportation. Roller skates, scooters, and skateboards also have wheels for movement.
