You can get tires for small aircraft that have a 1500+lb rating and so many plies they dont even need air,sometimes an small airport will have some hanging around in their scrap pile...they weigh more than regular tires too,and you can load them with fluid..
The only 2 bummers, is trying to mount them,they are usually used on rims that unbolt in two halves and use thick inner tubes..
I've mounted some on regular drop center rims and it was a bear of a job,the rim bead started to bend before the tire bead stretched over it and went on..also they are usually only ribbed tread and nearly bald,so you'll need chains for good traction..but they'll be hard to puncture..
