Reinventing the wheel

[LongDistance]

Interesting research into poly pneumatic tires https://www.rubbernews.com/assets/PDF/RN86184218.pdf

@RipTideSports Weren’t you working on something along these lines?

[ShutterShock]

@Nacho has Xcell tires on em so I’m pretty sure they fit nice

It might have something to do with that, not sure

@b264

If you take them at 45 degrees and don’t go too slow, you’d be SHOCKED what you can go over. Both of those are very important though. If you slow down because it’s scary or if you take them head-on, it’s bad news.

Yes definitely

@tech.shit

aren’t airless tires being used on mars rovers n shit? and ultra heavy machinery?

Things that need reliability and don’t care about rolling resistance, yes. Compressed air has higher rebound than any rubber AFAIK, so airless tires will find pneumatics hard to beat there.

[ShutterShock]

Also the airless tires being used on mars are often made out of metal lol

I think Doug over at Momentum is our best chance at reinventing the ESK8 wheel. If the current version he is manufacturing works well, maybe the design could be applied to a larger wheel.

[Flyboy]

Lol yeah, if someone made an esk8 with solid aluminum wheels they should run it at Bonneville

[tech.shit]

OMG this is what I need. reliability and absorption without compressed air!

[LongDistance]

Hit em up for an esk8 sample lol

I think @Nacho has the xcells on newbees.

[ShutterShock]

I think he has shared pictures of the xcell ones on there too, he also has tried the meepo tires on them

I could be remembering wrong tho

[Shadowfax]

found it - no test fit unfortunately. Still gotta wait on someone to try it out.

Best pneumatic tires?

It’s a tight fit on the gt3 KEVBALLs I tried putting mine on the other day and I didn’t wanna shave the bead But the cyclone tire fits perfectly on the gt3 And you might like it because there is a little bit of a crown and it’s a soft compound [image] [image] [image] Newbees on the left One with a xcell tire the other one with a cyclone Red gt3 is on the right All three at 35psi

Small wheels like metro 155 give that little extra performance which is good on the track. For fast street riding, for me, they were detrimental to my right (goofy) knee, along with other factors like deck stiffness and weight. Switching to stretched 8 inch Kenda’s I didn’t notice much performance loss for street riding but a lot more comfort. My knee is still pretty messed up from the above mentioned, going to 10 inch tires and suspension now. Tire testing has gone well so far, way more comfortable, maybe a little more sluggish, similar effeciency… For street riding, 8 inch+ imo; for track, the tire with the most grip.

@Shadowfax

Also more rubber / wider contact point should give better grip

Not necessarily.

[Shadowfax]

@Linesflag why not?

[brown5tick]

Cos, like I said…

@brown5tick

bigger contact patch (and constant weight) = less pressure = less grip.

[LongDistance]

Elaborate

[Shadowfax]

I’m not following your logic there. bigger contact patches and lower pressures usually result in more grip, not less.

[brown5tick]

A bigger contact patch means a greater physical area over which weight is applied. Pressure is a function of force over area, so same force and bigger area = less pressure. Mechanical grip is a function of pressure. Less pressure, less grip.
