Default lightest wheels

As I have been building larger planes I have been in need of larger wheels. I am still in the 2-3 lb range at max, so weight is a concern. I am not talking about spoked wheels, which I use a lot on scratch-builds, but balloon-style tires (for grass or rough terrain). I am finding that wheels in the 3-4 inch diameter range, even those described as "light," really aren't so light. The hangar-9 3 1/2" Pro-Lite wheels I just received from Horizon weigh in at 3.65 oz. per pair! That's a real hit on an 1-2 lb airplane. They not only add a great deal of weight, they throw off the CG if added to a built airplane. Unfortunately, even major manufacturers like Du-Bro don't list the weights of their wheels, usually only the axle size. Anybody know of balloon-style wheels in the 2-4" diameter range that are truly light - say...less than an ounce, or ounce-and-a-half each?

I'm partial to Dubro Super Lite. They only go up to 3" though.

Dave Brown Lite Flite go up to 5" with a similar foam tire. The 4" is 1.65oz each.

The Du-Bro Super-Lites look good at less than 1/2 oz each. Doubt you could get much less than that on a 3" wheel. Don't really shop Tower much, but it's nice they list the weights.

I make my own wheels out of dollar tree foam board using a dremel with a circle cutting attachment. i cut out a few circles, peel the paper off and glue together, then just sand to round the edges and clear coat, put a small tube through the hub area and you are good to go and very light.
