WCP Pneumatic Wheels
 

Is anyone planning on using these? I'm just wondering how these wheels compare to the 8" AM wheels.

Re: WCP Pneumatic Wheels
 

Since there is a thread about this, we've gotten numerous emails about availability.

General note, any new orders since 1/14 will have a one week lag time. Customers before that will be getting hubs this week. Our goal is to get all customers taken care of by this weekend.

Please email support@wcproducts.net for any further specific order questions.

Thanks!

Re: WCP Pneumatic Wheels
 

What are the weight of these?

Re: WCP Pneumatic Wheels
 

We built a fully functional prototype with these wheels this past weekend and have been pleased with the results.

Having a COTS live axel pneumatic wheel is a huge time saver for us! Thanks WCP!

To answer the weight question, we weighed a diamond tread wheel (with hub) and got right around a pound. I can get a more exact number tonight.

Re: WCP Pneumatic Wheels
 

it would be major awesome if you could post some videos of it in action.

Re: WCP Pneumatic Wheels
 

You could watch 1114 in 2012 or 2010. It's the same tire.

Re: WCP Pneumatic Wheels
 

We are going with an 8wd with the 6" diamond tread tires/tubes from WCP, but we are using the 6" pneumatic tire plastic hubs from AndyMark: http://www.andymark.com/product-p/am-2469.htm

Re: WCP Pneumatic Wheels
 

In addition to the weight, I'm curious about the actual measured diameter of the wheel at the crown of a nominally inflated tire. Is that something you can measure and publish here?

We haven't received ours yet, and are designing around a 6 inch diameter. However our clearances between wheels are pretty tight and It'd be nice to know the real life diameter.

Re: WCP Pneumatic Wheels
 

2010 only. In 2012 we used the 8" AM wheel.

Re: WCP Pneumatic Wheels
 

Andy,

Absolutely. I will take dimensions today and post. I assume you will want crown diameter and wheel width at various psi (I'm thinking 0-50 psi in 10 psi intervals?)

I will also take an accurate weight today.

Any other requests regarding this wheel?

Sorry, can't post any video or pictures of our test base. But I'll make a base-less claim (pun intended!) and say we're killing the defenses this year, we are very happy with the results!

Re: WCP Pneumatic Wheels
 

Mike, thanks for digging into the details on these wheels for those of us still waiting to get our set. Could you along with the diameters at each of those pressures additionally measure the width of the tire? Thanks!

Re: WCP Pneumatic Wheels
 

The width under load would be awesome. Contact patch measurements, etc.

Pretty much any measurement you could throw at us wouldn't go to waste.

Re: WCP Pneumatic Wheels
 

RC,

Can you comment if these wheels are rated for Highway use?

Kind Regards,

Re: WCP Pneumatic Wheels
 

We received ours yesterday. On the side they say "Not for Highway Use"

Re: WCP Pneumatic Wheels
 

They are not rated for highway use.

That being said, we did shoot frisbees with them at 6krpm, which is 107 mph, so they'll totally be fine if you're not breaking the speed limit ;)

Re: WCP Pneumatic Wheels
 

All,

I took some measurements this afternoon, as well as pictures of my "data".

Spreadsheet can be found here.

Pictures of data can be found here.

Hope this helps!

Re: WCP Pneumatic Wheels
 

Outstanding! BZ.

Re: WCP Pneumatic Wheels
 

Much appreciated, I'll share the data with the team. Thanks!

Re: WCP Pneumatic Wheels
 

Thanks again for the data, one additional question.

Has anyone had their hands on both the Zig Zag and Diamond wheels and tires. We are looking to order our second set and would love to hear some feedback as we have yet to receive our Zig Zag sample. Thanks!

Re: WCP Pneumatic Wheels
 

Would love to help you, but we're still waiting for Zig Zag too. Seconding the request for feedback while we wait. :)

Re: WCP Pneumatic Wheels
 

Hey Mike could you also measure the amount four wheels contacting the ground compress with the full robot weight on them with bumpers at those psi's. Ie how much drop center you loose.

Thanks For the Data

Re: WCP Pneumatic Wheels
 

Has anyone else had a had a time getting any response from WCP lately? We ordered wheels and all was going fine, was told late last Thursday that they were shipping out Friday morning. We never got a confirmation email of shipping or tracking number. Ive triend calling and emailing to find out what was going on but have not got an answer since last week. Im sure they are swamped and working their tails off but just a little worried with lack of response.

Re: WCP Pneumatic Wheels
 

Email me here please, if I don't respond in a day just re ping.

rc@wcproducts.net

We've been swamped and working 16 hour days to get stuff to customers. We only have a handful of teams who haven't gotten wheels, basically all wheels will be done and shipped by this sunday. We are overnighting or 2 day shipping all wheels to customers. Also note please just email, its the fastest way to get a reply.

RC

Thank you for responding, so fast your service has been so outstanding so far thats why I worried when my last few emails were not replied to. Customer service goes a long way these days and you guys have been outstanding, Ill be recomending your business to other teams.

Thanks
