The solid tires from aliexpress are pretty cheap @ from 13USD

They don't seem to use pins like the Tannus, so I am not sure how well they stay on. They have the same wet weather low grip issues according to a reviewer, and wet weather would be the only time I would want to use them.
I wonder if it would be possible to DIY some spiked tires for snow by driving nails up through the base of these. 13 USD plus a few hard nails would be cheaper than tires with spikes. We only have a few days of snow so I have not yet purchased tyres with spikes. (Gosh I am so inventive! Not. Because on second thoughts, the nails would be driven into the rims and probably rip holes in the tyres.)
Apparently Tannus, and perhaps the ones linked above from China are only as heavy as puncture resistant pneumatic tyres.
