Wheels FAQ

  • How can I slow down my wheels on my new skates?
    We suggest you tighten the axle nuts to create more friction, but be careful to not overtighten and damage the bearings.
  • How does the size of my wheels affect the speed ?
    A larger the wheel will have more roll with the least amount of effort. This will help you cover more surface area with the larger wheel with less effort and you will go faster and have a smoother ride.
  • What are the difference between indoor and outdoor wheels?
    You will need a "softer" wheel for outdoor skating and a "harder" wheel for indoor skating. A softer wheel will give you a better roll on the non-smooth surfaces such as sidewalks and streets. This is because the softer wheel will provide a better rebound for skating on uneven surfaces. Rebound allows for the wheel to "roll" over the uneven surface rather than bouncing over them with a harder wheel. A soft wheel typically has a lot of grip. A harder wheel will give you a better roll on smoother surfaces such as skating rinks. A harder wheel typically is a more slicker wheel (not a lot of grip).
  • What is the proper maintenance for my wheels?
    You will need to check your roller skate wheels from time to time to make sure they are spinning properly and have not become excessively worn. If the wheels are not spinning freely you should check for damage, or buildup from dirt or other debris. If the roller skate wheels are damaged they should be replaced. offers a lot of replacement rollerblade wheels for you to choose from. If they are simply dirty, take the time to remove and clean the wheels as necessary.
  • Why it's important to rotate your skate wheels and how often should they be rotated?
    Rotating your wheels regularly will make them last longer, because they will wear more evenly. Skate wheels usually wear out faster on one edge than the other, and most people wear down some of their wheels faster than others. 

    When to Rotate Skate Wheels:
    You will know it's time to rotate your skate wheels, when you see that one side of your wheels - usually the inside edge - is wearing down more quickly than the other. Another signal is when you can see that some of your wheels are noticeably larger than others, but if you can see this difference, you have probably waited too long.

    After You Rotate Your Wheels:
    Freshly rotated wheels can feel a bit strange when you skate on them and it can be difficult to keep your balance. This problem can be reduced by rotating your wheels frequently, and by rotating the largest wheels to the front and back positions. If you your wheels do feel strange after rotating, they will feel normal again after a few days of hard skating

  • What is the difference in roller skate wheels?

    There are basically 4 main different types of roller skate wheels:

    1) Speed Wheels - Designed to grip the skating floor and allow you to gain traction while gaining speed.

    2) Artistic/Dance Wheels - Designed to be hard wheels that are not "grippy" to allow for the dance style moves in skating.

    3) Outdoor Wheels - These are softer wheels that are designed to be able to absorb the uneven terrain of outdoor skating surfaces (e.g. trails, sidewalks, boardwalks, roads).

    4) Derby Wheels: The wheels are designed for the sport of Roller Derby. These allow the different positions in Derby to be able to stop quickly, go quickly, and go at fast speeds.

  • What does the wheel hardness and the wheel diameter mean?
    Wheels have 2 numbers on them that count.

    1) The Wheel Hardness is measured on the Shore scale:

    Either on the D scale or the A scale
    D scales are for harnesses of Plastic Compound Wheels
    A scales are for harnesses of Urethane Compound Wheels

    The lower the Number the softer the wheel, this provides more grip with a little less roll. The higher the number the harder the wheel this provides a little less grip with more roll.

    2) The Wheel Diameter is measured in millimeters

    57mm are used for Freestyle/Artistic skating, primarily. (the 55mm are based on a lowering of the center of gravity).
    62mm are used for Speed & Derby skating. Also for indoor quad wheels (are based on just a small lowering of the center of gravity).
    60mm - 70mm are used for Outdoor skating. 

  • How is the size of a skate wheel measured and what are the range of rollerblade wheel sizes?
    The diameter or height of a skate wheel is measured in millimeters (MM). Wheels used for skates range from approximately 40 MM to 100 MM in diameter.

    Small wheels will provide the maneuverability needed for aggressive skating, figure skating, roller dancing, and hockey.

    A larger wheel will provide the smooth ride and faster speed that is desirable for fitness and speed skating, however accelerating from a stop to full speed will require more effort on very large wheels.

    Before you purchase new wheels for your skates, make sure the wheel size you are buying will fit on your skates and frames. 

    And remember when buying wheels bearings do not come with your new wheels.

  • What are hubs?
    Soft wheels below 84A need a hub to reinforce the bearing seat in the wheel. Under normal conditions, an 84A wheel will hold the bearings, but not under extreme conditions. Hubs are used on harder wheels only to lower the weight of larger wheels. Usually nylon or aluminum hubs are much lighter than the urethane they replace. Metal hubs are preferred over nylon hubs to produce a much stiffer wheel and provide a better feel to the top end skaters. Nylon hubs tend to flex while skating. 

  • How do I change the wheels on my quad skates?
    1) Unscrew the nut from each wheel with your skate tool. Place the tool over the nut, and turn it counterclockwise until the nut comes off.
    2) Remove the wheels from their bolts.
    3) Put the new wheels on the bolts.
    4) Put the nuts back on the bolts. Slide the nut onto the bolt, flat end first, and turn it clockwise with your fingers. Finish tightening the nuts with your skate tool.

    Test the wheels to make sure the nuts aren't too tight. Spin each wheel with your fingers. The wheel should spin freely. If the wheel doesn't spin or is jerky when it spins, the nuts are to tight and need to be loosened.
  • Why do my wheels have holes in them?
    Top end wheels for jam skating, inline speed skating or track skating are made from a material called POLY BD. This specific material has exceptional grip while providing excellent rebound yet remains stiff enough to deliver a quality roll. The POLY BD also has a very high viscosity which means it pours very slowly when cast and as it cures, tiny air bubbles are caught inside the wheels. These tiny air bubbles show up as holes in the wheel when the running surface is trimmed, as well as, when the wheels wear down and more holes come to the surface.

    Do not worry about the holes, these bubbles do not affect the performance of the wheels and in fact, they prove that the material is truly POLY BD which enhances the performance of the wheels on skating surfaces.

  • How do I tighten or loosen the wheels on my quad skates?
    Flip the first skate over, wheel side up. Locate the two external tension nuts at both of the wheel axles.

    1) Attach the correct socket wrench (usually 11/16 inch) to the ratchet body of your wrench.

    2) Fit the wrench on to the bolt and move the handle right and then left, until the nut reaches the appropriate tightness.

    3) Feel the nut with your fingers to test the tightness. Loosen or tighten as needed. A medium tightness is recommended.

    4) Repeat on the final three nuts.
