Ride Style

Downhill - To go fast and stay in control, you want a big wheel with a lot of contact with the pavement.

Carving/Cruising - Carving/cruising wheels meet the needs of many different skate disciplines but generally, have a good roll speed and are soft enough to handle craggy streets riddled with cracks and rocks.

Core Placement

Centerset - The hubs in these wheels are set equidistant from the lips, resulting in an even wear and a controlled slide.

Word to the wise: They can be rotated (like your car's tires) to promote even wear and a longer lifespan.

Wheel Edge

Square Lip - The most grip allowing you to carve deeper and take tight lines around corners without worrying about losing traction.

Surface Type

Smooth - The natural shiny finish provides extra grip for railing corners and is more responsive when pumping/carving compared to wheels with a stone ground finish.

Wheel Features

Race Formula - This is Sector 9's fastest and most evenly wearing urethane compound.


78a - The most common durometer we see amongst cruiser wheels. They have great grip for cornering and easily roll over cracks, small rocks and the like.

Sector 9 Race Formula Steamroller 73mm Longboard Wheels - yellow (78a)
First pair of wheels I’ve ever bough (besides the stock ones on my complete). Very good so far. Definitely get some speed, and I don’t feel much when I run over small rocks, cracks, etc. good for cruising

These things (78A) hold on to the road like crazy, I don't slide, nor would I even try to on these things. They are super wide and center set, so make sure they would fit on your precision or specialty trucks. I have stalkers and they didn't fit, but they work on almost any other cast truck don't worry. Its just that stalkers have flared end where the axle step starts. I put them on cal 50's and they are just so grippy. Huge too, roll speed is insane because of it. They will literally steamroll any rocks and sticks out of your way, too. move over, tiny slalom wheels.
*setup= Arbiter 36, Cal 50's, Bones super 6, Steamrollers. Real downhill machine.

Can these work for going around school? What would you recommend?

Yes these would be perfect for that! These are softer and will be good for cruising around
