I have has Fedima Trial ade tyres for three years and they have performed well in all situations, except they are very poor when driving sideways on a slope due to the tread pattern, other than that they are great tyres. Going back to the orginal question if you are not taking the vehicle on the road you may want to consider Greenway alligators very cheap tyres in comparisen to the others althougth they are retreads they work well, I have a freind who uses them and very rarely gets stuck, hope this helps
