I remember the first time I slapped a set of shiny new polyurethane wheels onto my old skateboard. Everyone swore by them, saying they were the perfect blend of grip and speed. I imagined gliding like a pro, effortlessly carving up the pavement. What I got was a bone-rattling ride that felt like I was skating on rocks. It made me wonder: are polyurethane wheels soft? The marketing hype often paints a rosy picture, but the reality can be a lot harsher, and frankly, a lot more expensive if you buy the wrong ones.
So, let’s cut through the noise. We’re going to talk about what polyurethane wheels actually feel like, why they’re so popular, and what you need to know before you hand over your cash.
What’s the Deal with Polyurethane Anyway?
Alright, let’s get down to brass tacks. When people ask are polyurethane wheels soft, they’re usually thinking about that cushy, shock-absorbing feeling you get from, say, a really good pair of running shoes. The short answer is: it depends. Polyurethane itself is a versatile plastic, and its hardness is measured on the Durometer scale, typically the ‘A’ scale for things like wheels. This scale goes from 0 to 100. Think of it this way: the higher the number, the harder the material. So, a wheel rated 75A is going to feel a lot softer than one rated 99A.
Most skateboard and longboard wheels, which are probably what most of you are thinking about when you ask about these wheels, usually fall somewhere between 75A and 101A. That’s a pretty wide range, right? A 75A wheel, for example, is going to feel noticeably softer and grippier. It’ll absorb vibrations from rough surfaces like cracks and pebbles much better, giving you a smoother, quieter ride. This is often what people are looking for when they want to cruise around town or skate on less-than-perfect pavement. They’ll feel a bit squishy under your weight, almost like a dense rubber.
On the flip side, a 99A or 101A wheel is significantly harder. These are your typical street skating wheels. They’re designed for smooth surfaces, skate parks, and doing tricks. They’ll feel much more direct, transferring more of the road’s texture to your feet. You’ll hear more of the rattle and feel more of the bumps. So, to directly answer the question: no, not all polyurethane wheels are soft. The softness is entirely dictated by their durometer rating.
I’ve made the mistake of buying hard wheels for cruising way too many times in my younger days. I’d see a cool graphic or a sweet deal, grab them, and then spend the next week regretting it as every tiny pebble felt like a boulder. Learning the durometer rating is step one in not wasting your hard-earned cash. The material itself is great – durable, has good rebound – but you absolutely must match the hardness to your intended use. Trying to grind rails with 78A wheels is a recipe for frustration, and trying to cruise your neighborhood with 101A wheels is just plain uncomfortable.
Why the Hype? The Good and the Overrated
So, if not all polyurethane wheels are soft, why are they so darn popular? Well, polyurethane, as a material, has some fantastic properties. It’s incredibly durable, meaning these wheels can take a beating and last a long time, especially compared to older materials like clay or even early urethane formulas. They have excellent rebound, which means they snap back to their original shape after being compressed, giving you a lively feel and good speed. Plus, you can mold them into pretty much any shape and color imaginable, which is why you see such a huge variety of designs out there.
The real reason polyurethane took over, especially in skateboarding and rollerblading, is its balance of grip and slide. Depending on the hardness, you can tune how much grip you get. Softer wheels (lower Durometer A) offer more traction, which is great for carving, downhill, or just generally feeling more planted. Harder wheels (higher Durometer A) offer less grip, allowing you to slide your board or skates more easily for tricks like powerslides or grinds. This adaptability is key. You can get a polyurethane wheel that’s perfect for cruising your local streets, another perfect for ripping up a skatepark, and yet another for long-distance pushing.

However, there’s definitely an element of ‘everyone else is doing it’ hype. Sometimes, brands will slap a fancy name on a standard polyurethane compound and charge double. I’ve seen wheels that claim to be ‘super soft’ and ‘ultra-smooth’ that, in reality, are just regular 80A wheels with a hefty markup. The common advice you’ll often hear is that ‘you need the hardest wheels for tricks and the softest for cruising.’ While there’s truth to that, it’s oversimplified. There’s a sweet spot in the mid-range (say, 90A-95A) that works surprisingly well for a lot of people who do a bit of everything. Don’t automatically assume the most expensive or the one with the wildest marketing is the best for you.
My own experience with this is a prime example. I once bought a set of wheels that were advertised as ‘gravity-defying’ and costing a small fortune. They were rated 97A. I thought, ‘Okay, a bit harder than my usual cruising wheels, but they’ll be good for the occasional trick.’ Wrong. They felt like riding on concrete, and the vibration was so bad my feet were numb after twenty minutes. I ended up trading them for a set of standard 85A wheels, which felt like a cloud in comparison. The branding and the inflated price tag meant absolutely nothing for my actual riding experience.
The Durometer Scale: Your Best Friend
Let’s talk numbers, because this is where the real answers lie. The Durometer A scale is what you need to pay attention to. It’s not just a number; it’s your roadmap to understanding whether a polyurethane wheel will feel soft, hard, or somewhere in between. As I mentioned, it ranges from 0 to 100, but for wheels, you’re typically looking at the 75A to 101A range. Higher numbers mean harder wheels, lower numbers mean softer wheels.
Here’s a breakdown that’s actually useful:
| Durometer Rating (A) | Feel/Ride | Best For | My Verdict |
|---|---|---|---|
| 75A – 85A | Very soft, excellent vibration absorption, super grippy. Feels smooth on rough surfaces. | Cruising, longboarding, rough pavement, commuting, beginners wanting comfort. | Absolute must-have for comfortable cruising. Don’t skimp here if you want to avoid rattling your teeth. |
| 86A – 95A | Medium hardness. A good balance of grip and slide. Still offers decent vibration dampening. | All-around riding, skateparks with varied surfaces, some street skating, transition skating. | The versatile option. If you do a bit of everything and can’t justify multiple wheel sets, this is your sweet spot. |
| 96A – 101A+ | Very hard, minimal vibration absorption, less grip, more slide. Feels very direct and fast on smooth surfaces. | Street skating, technical tricks, smooth skate parks, grinding. | Only go this hard if you know you need it for specific tricks or skatepark environments. Otherwise, you’re signing up for a rough ride. |
Understanding this scale means you’re already ahead of most people just looking at pretty pictures. When you’re shopping, ignore the fancy names and focus on that number. If someone tells you a 90A wheel is ‘soft,’ they’re either misinformed or they have the sensitivity of a paving stone. Conversely, if they say a 78A wheel is ‘hard,’ well, they’re probably just used to riding on clouds all the time.
I remember one time I was helping a buddy pick out new wheels for his cruiser board. He was eyeing some bright pink ones that looked cool, but they were 99A. He said, ‘They look fast!’ I had to explain that while they might be fast on a mirror-smooth surface, they were going to make his ride feel like a jackhammer. We ended up with a set of 82A wheels, and the change was night and day. He went from complaining about every crack to actually enjoying his rides.
Common Mistakes and What to Avoid
The biggest mistake people make when buying polyurethane wheels is assuming they all behave the same. This is where the question ‘are polyurethane wheels soft’ really gets muddled. They are not. They are a material, and like steel or wood, they can be engineered to be different hardnesses. So, buying based on brand name or aesthetics alone is a rookie error that costs money and leads to disappointment. (See Also: Can A Coat Of Polyurethane Make Paper Mache Water Proof )
Another common pitfall is buying wheels that are too hard for your intended use. This is especially true for beginners or casual riders who just want to cruise. They might see the harder wheels (95A and up) in skate shops and think that’s what you’re supposed to get. This leads to a jarring, uncomfortable ride that can actually make skating less enjoyable and potentially more dangerous, as you’re more likely to lose grip on uneven surfaces. Trust me, I’ve had my feet sting for days after a long session on wheels that were too hard.
Conversely, some people trying to learn tricks might opt for wheels that are too soft. While softer wheels offer more grip and stability, they can make sliding and popping the board or skates much harder. The wheels might feel sluggish, and you’ll lose momentum quickly. It’s a trade-off. If you’re primarily doing tricks, you generally want to lean towards the harder end of the spectrum. If you’re cruising or skating rough terrain, softer is almost always better. There’s no magic bullet, but understanding the Durometer scale is the first step to avoiding these common mistakes.
I also see people getting hung up on wheel diameter, which is another factor that affects the ride, but often gets overlooked when discussing softness. Larger wheels roll over obstacles more easily and maintain speed better, but they can feel a bit heavier. Smaller wheels are lighter and more responsive for tricks but can get bogged down by debris. While not directly related to the polyurethane itself being soft, the combination of diameter and durometer is what truly defines the ride experience. Don’t just look at one spec and assume you know how it will feel.
Real-World Use: Where Do They Shine?
So, where do polyurethane wheels truly excel? In almost every wheeled application you can think of, really, once you get the hardness right. For skaters and rollerbladers, they are the undisputed king. As we’ve hammered home, the ability to tune the hardness means you can have wheels perfect for a smooth skate park, gnarly street skating, or just cruising to the coffee shop. The durability means they last, and the rebound gives you that satisfying ‘pop’ or acceleration.
Beyond personal transport and recreation, polyurethane wheels are found everywhere. Think about the wheels on your office chair. Those usually aren’t super hard plastic; they’re often a softer polyurethane blend to protect your floors and provide a quieter, smoother roll. Shopping cart wheels? Often polyurethane. Industrial casters on heavy equipment? You guessed it – polyurethane, chosen for its load-bearing capacity and resistance to wear, often in various hardnesses depending on the floor surface and the load.
In the world of electric scooters and e-skateboards, polyurethane wheels are dominant. They provide the grip needed for acceleration and braking, and the right hardness can significantly improve ride comfort over less-than-ideal urban surfaces. You’ll see a range of hardnesses here too, from softer, pneumatic-like tires (which are technically different but serve a similar comfort purpose) to solid, harder urethane wheels designed for speed and efficiency on smooth paths. The key is always matching the wheel’s properties to the environment and the rider’s needs.
I once had an electric scooter with incredibly hard, solid wheels. It was like riding a bucking bronco. Every little pebble felt like a pothole. I ended up swapping them out for a set of softer, slightly larger polyurethane wheels. The difference was astronomical. I could actually ride for more than ten minutes without my spine vibrating loose. This experience solidified for me that the material is only half the story; the specific formulation and hardness are what truly matter. (See Also: Can A Coat Of Polyurethane Cover A Smell )
Practical Tips for Choosing and Caring
When you’re looking for your next set of wheels, here are a few practical tips that have saved me a lot of headaches (and money):
- Know Your Terrain: This is the absolute #1 rule. Are you skating on cracked sidewalks and rough asphalt? Go soft (75A-85A). Are you hitting smooth skate parks and doing tricks? Go harder (95A-101A). If you do a mix, aim for the middle ground (86A-95A) but understand it’s a compromise.
- Read Reviews (Critically): Don’t just look at star ratings. Read what people are saying about the feel of the wheels. Are they described as ‘smooth,’ ‘grippy,’ ‘chattery,’ ‘fast,’ or ‘slow’? Look for comments from people who ride in similar conditions to you.
- Don’t Chase the Latest Fad: Brands love to release new ‘proprietary formulas’ that sound amazing but are often just slight variations of standard compounds. Stick to reputable brands known for consistency unless you have a specific reason to try something new.
- Consider Diameter: While hardness is key to ‘softness,’ wheel diameter impacts how easily you roll over obstacles and maintain speed. Larger wheels (56mm+) are better for cruising and rougher surfaces, while smaller wheels (under 54mm) are lighter for tricks.
- Bearings Matter Too: Remember that your bearings also play a huge role in how smooth and fast your wheels roll. Even the softest, nicest wheels will feel sluggish with dirty or worn-out bearings. Keep them clean and lubricated.
- Proper Storage: If you have multiple sets of wheels, store them properly. Keep them out of direct sunlight and extreme temperatures, as this can degrade the polyurethane over time and affect their performance.
Caring for your polyurethane wheels is pretty straightforward. Most of the time, they just need a wipe-down to remove dirt and grime. Avoid exposing them to harsh chemicals or solvents, as these can break down the material. If you get flat spots (where the wheel wears unevenly from constant sliding or braking in one spot), there’s not much you can do to fix them other than rotating them occasionally, though on a board, you might switch wheel positions to try and even out wear. Ultimately, they are a consumable item, and even the best ones will wear out eventually.
Are Polyurethane Wheels Good for Rough Surfaces?
Yes, but only if they are on the softer end of the Durometer A scale (typically 75A to 85A). Softer polyurethane wheels have more give and can absorb vibrations and bumps from rough terrain like cracks, pebbles, and uneven pavement much better than harder wheels. This leads to a significantly smoother and more comfortable ride.
Can Hard Polyurethane Wheels Be Soft?
No, the definition of ‘soft’ in polyurethane wheels is directly tied to their Durometer rating. Harder wheels, by definition on the Durometer A scale (usually 95A and above), are not soft. They offer less shock absorption and transmit more of the surface’s texture to the rider. If a wheel is rated hard, it will feel hard, regardless of branding.
What Is the Difference Between Soft and Hard Polyurethane Wheels?
The primary difference lies in their Durometer A rating. Soft polyurethane wheels (lower numbers, e.g., 75A-85A) provide more grip, absorb more shock, and offer a smoother ride, ideal for cruising and rough surfaces. Hard polyurethane wheels (higher numbers, e.g., 95A-101A) offer less grip, slide more easily, transmit more vibration, and are faster on smooth surfaces, making them suitable for tricks and skate parks.
Do Polyurethane Wheels Wear Out?
Yes, polyurethane wheels do wear out over time and with use. Factors like the hardness of the wheel, the type of riding (tricks vs. cruising), the surfaces you ride on, and even your weight can affect how quickly they wear down. Harder wheels can sometimes develop flat spots more easily if you slide frequently. Eventually, they will become smaller and may need replacing.
Final Verdict
So, to circle back to the burning question: are polyurethane wheels soft? They can be, but they aren’t inherently so. It all comes down to the Durometer A rating. Don’t get fooled by marketing jargon or pretty colors. If you want a soft ride, look for those lower numbers. If you’re doing tricks on smooth concrete, you’ll want the higher numbers, and yes, that will feel hard.
My advice? Spend a few extra minutes researching the specific durometer rating and reading reviews from people who ride like you do. It’s the single best way to avoid buying a set of wheels that will make your teeth rattle or hinder your progress. Your feet, and your wallet, will thank you.
Next time you’re looking at wheels, remember that durometer number. It’s the real secret sauce, not the fancy graphics.
