When brands think about custom skateboards, they usually focus on the deck—the graphics, the shape, the construction. But for complete skateboards, the wheels are just as important. They affect how the board rolls, how it grips, how it handles rough surfaces, and how it performs in different skating disciplines. Choose the wrong wheels, and your complete skateboard will feel sluggish, unstable, or uncomfortable—no matter how good the deck is.
For OEM orders, wheel selection is a critical product development decision. It’s not just about picking a color or a brand; it’s about specifying the right size and hardness (durometer) for your target market and intended use. Get it right, and your complete skateboards will perform the way your customers expect. Get it wrong, and you’ll face returns, complaints, and a damaged brand reputation.
The challenge is that wheel size and hardness aren’t one-size-fits-all. A wheel that’s perfect for a beginner’s cruiser is wrong for a technical street setup. A wheel that works for a kids’ board is unsuitable for a downhill deck. Understanding the relationship between wheel size, hardness, and intended use is essential for anyone sourcing complete skateboards.
In this guide, we’ll break down everything you need to know about choosing skateboard wheel size and hardness for OEM orders—what the numbers mean, how they affect performance, how to match wheels to your target market, and what to specify in your product documentation. Whether you’re developing a complete skateboard line or sourcing wheels as components, this article will give you the technical clarity you need. And when you’re ready to discuss your wheel specifications, you can request a quote to get started.
Understanding Skateboard Wheel Size
Wheel size is measured in millimeters (mm) and refers to the diameter of the wheel. It’s one of the most important factors affecting how a skateboard performs—and one of the easiest to get wrong.
Common Wheel Sizes
Skateboard wheels typically range from 48mm to 75mm in diameter, though most street and park wheels fall between 50mm and 60mm.
| Size Range | Typical Use | Characteristics |
|---|---|---|
| 48–52mm | Technical street skating | Lightweight, quick acceleration, less top speed |
| 52–55mm | All-around street and park | Versatile, balanced performance |
| 55–60mm | Park, transition, cruiser | Faster roll, more stability |
| 60–65mm | Cruisers, filmer boards | Smooth roll, comfortable on rough surfaces |
| 65–75mm | Longboards, downhill | Maximum speed and stability |
How Wheel Size Affects Performance
Acceleration: Smaller wheels accelerate faster because they have less rotational mass. This is why technical street skaters prefer 50–53mm wheels—they need quick acceleration for tricks.
Top speed: Larger wheels have a higher top speed because they cover more ground per rotation. Cruisers and longboarders prefer larger wheels for this reason.
Stability: Larger wheels are more stable at speed and roll over rough surfaces more easily. Smaller wheels are more responsive but less stable.
Weight: Larger wheels are heavier. This affects the overall weight of the skateboard and can impact trick performance.
Wheelbite: Smaller wheels reduce the risk of wheelbite—where the wheel makes contact with the deck during turns. Larger wheels increase wheelbite risk, especially on decks with aggressive concave or loose trucks.
Choosing Wheel Size for Your Target Market
For kids’ skateboards: 50–54mm. Smaller wheels are lighter, easier to accelerate, and reduce wheelbite risk for younger, lighter riders.
For beginner completes: 52–54mm. A versatile size that works for learning tricks and cruising.
For street completes: 50–53mm. Smaller, lighter wheels for technical tricks and quick acceleration.
For park completes: 53–56mm. Slightly larger wheels for speed and stability on ramps and transition.
For cruiser completes: 56–60mm. Larger, softer wheels for smooth rolling on rough surfaces.
For longboards: 65–75mm. Maximum size for speed, stability, and rolling over obstacles.
Understanding Skateboard Wheel Hardness (Durometer)
Wheel hardness is measured on the durometer scale, typically using the A scale for skateboard wheels. The higher the number, the harder the wheel.
Common Durometer Ratings
| Durometer | Hardness | Typical Use | Characteristics |
|---|---|---|---|
| 78A–85A | Soft | Cruisers, rough surfaces | Smooth ride, good grip, less speed |
| 85A–95A | Medium | All-around, park | Balanced grip and speed |
| 95A–101A | Hard | Street, skate park | Fast, slideable, less grip |
| 101A+ | Very hard | Technical street | Maximum speed, minimal grip |
How Hardness Affects Performance
Grip: Softer wheels grip the surface better. They’re ideal for rough or slippery surfaces. Harder wheels slide more easily, which is preferred for tricks that involve sliding.
Speed: Harder wheels roll faster on smooth surfaces because they have less rolling resistance. Softer wheels are slower on smooth surfaces but faster on rough ones because they absorb vibration.
Comfort: Softer wheels absorb more vibration, providing a smoother, more comfortable ride. Harder wheels transmit more vibration, which can be tiring on rough surfaces.
Durability: Harder wheels last longer on smooth surfaces. Softer wheels wear faster but perform better on rough surfaces.
Slide performance: Harder wheels slide more predictably, making them preferred for power slides and technical street skating.
Choosing Wheel Hardness for Your Target Market
For kids’ skateboards: 78A–85A. Soft wheels provide a smoother, more comfortable ride and are more forgiving for beginners.
For beginner completes: 85A–95A. A medium hardness that works for both cruising and learning tricks.
For street completes: 95A–101A. Hard wheels for speed, slideability, and technical tricks.
For park completes: 95A–101A. Hard wheels for speed and stability on smooth park surfaces.
For cruiser completes: 78A–85A. Soft wheels for a smooth, comfortable ride on rough surfaces.
For longboards: 78A–85A. Soft wheels for grip, comfort, and rolling over obstacles.
Matching Wheel Size and Hardness to Your Product Line
Wheel size and hardness work together. The right combination depends on your target market and the intended use of the complete skateboard.
Recommended Combinations by Product Type
| Product Type | Wheel Size | Durometer | Why |
|---|---|---|---|
| Kids’ skateboard | 50–54mm | 78A–85A | Lightweight, soft for comfort and safety |
| Beginner complete | 52–54mm | 85A–95A | Versatile for learning tricks and cruising |
| Street complete | 50–53mm | 95A–101A | Lightweight, hard for speed and tricks |
| Park complete | 53–56mm | 95A–101A | Slightly larger for speed, hard for smooth surfaces |
| Cruiser complete | 56–60mm | 78A–85A | Larger, soft for smooth rolling |
| Longboard | 65–75mm | 78A–85A | Maximum size and softness for speed and comfort |
Factors to Consider
Rider weight: Lighter riders (kids, beginners) benefit from softer wheels and smaller sizes. Heavier riders may prefer harder wheels and larger sizes for stability.
Surface conditions: Rough surfaces call for softer, larger wheels. Smooth surfaces (skate parks) call for harder, smaller wheels.
Skating style: Technical street skating favors small, hard wheels. Cruising favors large, soft wheels. Park skating favors medium-to-large, hard wheels.
Deck width: Wider decks often pair with larger wheels. Narrower decks pair with smaller wheels.
Truck height: Larger wheels may require riser pads to prevent wheelbite. Consider truck height when specifying wheel size.
Brand positioning: Premium brands may specify branded wheels from known manufacturers. Budget brands may use generic wheels that meet basic specifications.
Specifying Wheels for OEM Orders
When placing an OEM order for complete skateboards, you need to specify wheels precisely. Vague specifications lead to inconsistent products and unhappy customers.
What to Include in Your Specifications
Size: Specify the exact diameter in millimeters (e.g., “54mm”).
Durometer: Specify the hardness on the A scale (e.g., “99A”).
Color: Specify the wheel color, including Pantone references if matching brand colors.
Shape: Specify the wheel shape—standard, wide, narrow, conical, etc.
Graphic: If the wheels will carry your branding, specify the graphic, placement, and printing method.
Material: Specify the urethane formulation if you have preferences (standard, high-rebound, etc.).
Bearing seat: Specify the bearing seat type (standard, centerset, sideset).
Quantity per set: Specify how many wheels per set (typically 4).
Packaging: Specify how wheels are packaged (poly bag, box, etc.).
Working with Your Manufacturer
Your manufacturer can advise on wheel specifications based on your target market and price point. They may have standard wheel options that meet your needs or can source custom wheels from specialized suppliers.
If you’re sourcing complete skateboards, working with a complete skateboard manufacturer that offers integrated component sourcing simplifies the process. They can coordinate deck, truck, wheel, and bearing specifications to ensure everything works together.

Common Mistakes to Avoid
Even experienced product managers make mistakes when specifying wheels. Here are the most common.
Choosing Wheels Based on Looks Alone
The mistake: Selecting wheels because they look good, without considering performance.
The fix: Match wheel size and hardness to the intended use and target market. Aesthetics matter, but performance matters more.
Ignoring Durometer
The mistake: Specifying wheel size but not hardness, assuming all wheels of a given size perform the same.
The fix: Always specify durometer. A 54mm 78A wheel performs completely differently from a 54mm 101A wheel.
Using the Wrong Size for the Deck
The mistake: Pairing large wheels with a narrow deck, causing wheelbite.
The fix: Match wheel size to deck width and truck height. Use riser pads if necessary.
Overlooking Bearing Compatibility
The mistake: Specifying wheels that aren’t compatible with your chosen bearings.
The fix: Confirm bearing seat type and compatibility before ordering.
Skipping Samples
The mistake: Approving wheel specifications without testing a sample.
The fix: Always request and test samples before bulk production.
Inconsistent Specifications Across Orders
The mistake: Changing wheel specifications between orders without documenting the changes.
The fix: Document specifications in your product spec sheet and tech pack. Reference them for every order.
