Default Why not narrow wheels on quad skates...


I wonder why quad skates and cruise skateboards all have wide wheels, when we know from inline skates,
that narrow and bigger wheels is faster and provides less resistance.
I changed my skateboard wheels from 54 mm to narrow 76 mm wheels from my inliners, and what a difference.
My skateboard rolls much easier and faster especially on rough asphalt.
I've never seen this done before, but it works very well.
Somebody knows, why narrow wheels is normally not used on quad skates and cruise skatebuards /longboards?
I'm still inline skating, but about 3 month ago, I began to learn skateboarding.

They do make QualLine skates. I've only seen them at the local rink once. They tend to have a wide stance. Not sure why they aren't popular, other than they aren't from Australia

Narrow wheels tend to lean and roll over sideways, you need lateral stability in a quad to make the action work correctly.

Grip increases some when you narrow a quad wheel until the action vant be worked efficiently.

2 wheels, 99A 62mm tall.... A is 44mm wide B is 30mm wide.
B has more grip for most situations. Until the urethane reaches a shear point, at that point it will slip reguardless of the surface grip available. Another reason scotts urethane grips so damn well.

Smaller contact patch increases pressures, it helps. But it doesnt solve all the problems.

To grasp why too narrow inline wheels are unsuitable for serious quad skates and skating, you have to wrap your mind around the way that your push stroke must function to generate forward skating momentum/speed.

With Quad skates the direction of the push (once you are rolling at a decent speed) is pointed at 90 laterally outward, away from the direction of roll.
All four wheels stay in flat contact with the rolling surface (no wheel leanover), and to avoid having the wheels slipping laterally across the rolling surface as you push, a minimum amount of wheel width must maintain intimate contact with the surface during peak force of the push stroke, or grip will not be maintained. The urethane contact patch is not shaped right to grip enough to resist a strong quad push stroke.

Skateboards will not hold grip on curves if inline wheels are used, and they will quickly be shredded away down to the full width of the inline wheels as they slide through turns and shed speed.

Quads rolling inline wheels will also be shredded away until the wheels get flat all the way across, but this is just from the lateral pushing and slipping. Quads need about a minimum of 30mm wheel width to hold good grip during the push strokes.

Quadline skate wheels are a slap in the face. They pretend that a curved inline wheel profile will not immediately be shredded away down to a flat profile, but that is exactly what happens.
Are they total morons, or what? They need to make Quadline wheels that START OUT flat to the pavement --- NOT ROUNDED --- and even if flatted from the factory, the narrower inline wheels will still wear out much quicker than narrow quad wheels do.

Since the push with skateboards is DIRECTED rearward, not lateral, the inline wheels on them can roll fine and fast, but they will die a fast death from getting shreaded away as they go sliding through the curves faster than you want to go.

Thanks to you for the answers.
Because I'm a beginner on skateboard, I do not slide sidewards, I only enjoy, that it rolls easy and long time between every push. (until my wheels is worn out)

In a straight line, inline wheels work very well on skateboards. I have used 110mm inline wheels on my long board and the roll is excellent. Doesn't carve worth a darn, but the roll is nice.

^^This is about it.

One other thing. My first pair of quads (after modern urethane was invented) were used both indoors and out. The wheels lasted me literally forever. Literally 10+ years mostly in rinks with synthetic floors but plenty of outdoor hours.

My inline skates (and one of the reasons I took a break from them for 2 years to pick up longboarding) go through a set of wheels about every 1000 miles/6 months the way I skate recreationally. If I play hockey in a parking lot I can go through 3 sets of wheels in ONE AFTERNOON. When I played hockey on quads - no apparent wear to the wheels.

Since quads and skateboards have TRUCKS that do the turning, you do not need EDGES like ice and inline skates. So you NEED more of a wheel contact patch so you don't slide out on every turn.

If you don't keep your edges sharp on ice skates, guess what? Slide out on turns, slip under power pushing. And it is hard to mentally grasp that inline skate wheels have "edges", but trust me here, they do have functional edges.

Hope this helps! You wanna recycle your old inline skate wheels to your skateboard to save some cash? I can't blame you. If you are not sliding out while cutting a tight turn...rock on!

Thin metal wheels on granite, turn off the sound, boots are tied up past the ankle, makes him seem a bit stiff, but wow...

Yes, I have been thinking about buying some longboard wheels, but before I buy them,
I would I try the inline wheels, and I was very surprised.
The skateboard was very noisy, so I couldn't hear the cars. With the inline wheels it is silent.
Another advantage especially on the rough asphalt.
Next time I go to the skatehall I'll bring the original skateboard wheels with me.
They are easy too change back, if I shall try to skate ramps.

It apeard from the cut scenes that Donald O'Conner and Fred Astair had locked their wheels during the tap dance portions of thieir skate scenes. Not really sure, but this, (Gene Kelly) looks totally ligit.

Totally plausible with the Donald O'Conner video, but the Fred Astair and Ginger Rogers video is constant motion, so I don't think they were locked. I always thought Fred was known for "one take" scenes.

Regardless, that was some awesome talent on all these scenes. Can you image skating dressed like Gene Kelly or Fred Astaire?

I asked my mother-in-law and father-in-law about this, and they said it wasn't really like that. They dressed in casual clothes for casual activities. Hollywood strikes again.
