Tubeless 380X150-5

I'm planning on the Beringer wheel mains kit (9A), and I see that some have used 380X150-5 tires for a bit better soft-field tolerance. The ones I see available are marked as tube-type. Are there any that are sold as tubeless?

Here there's mention that Michelin makes one with the appropriate liner but I they don't mention a name/part number.

This builder is using Michelins with tubes.

Then again, they seem to come at a steep premium :rolleyes:, and they're out of stock.
 
What are you planning to do with the nose wheel? The fork will not allow you to up size that tire - with taller 380 tires on the mains, your plane will definitely have a more nose down attitude
The link you supplied (that still has pictures) show a tail dragger.
 
The stock tire is 13.5" vs 15" diameter, so only 0.75" additional height, but a full inch wider.

I don't have the fuselage on the legs yet (anyone have the mains to nosewheel distance?) but for some napkin math:

arctan(0.75/48) = 0.895 degrees
I think that's small enough to ignore, and keep the nose stock. As always, land on the mains and keep the nose light.
