Being desperate for a solid nose wheel ,I decided to make one.
Took a Dubro 2.5" dia soft wheel, cut a half inch slit in the top, pried it open with a piece of scrap wood and poured in warmed epoxy.
Its nice and solid.
We will see if it works.

did you balance it?

Good thought , I'll check that

It is heavier on one side, going to make another one with a mixture of micro ballons.

try chucking it up in a drill with an axle and spinning it fast and see if you get vibration, i had a solid tire that vibrated bad on the take off roll, replaced it and problem solved, i then cut the tire open and found a large air pocket in the material. now i spin all tires/rims before mounting them on a jet.
