I am looking at this tire as there are some good prices out there and I am in need of rear tires for my 1959 cub lowboy tractor. I see that Carlisle says tubeless type or can use with a tube . is it ok to mount these with no tubes ? it would be nice to not need a tube if I get a flat to just plug them as the rear wheel weights are a pita to remove and reinstall , any thoughts would help . I also see that these tires weight a lot more than the bkt, alliance , etc tires out there. Carlisle site says 82lbs and the alliance and the bkt are 42 and 44 lbs each. would these be a good choice for the cub low boy tractor, or are they to much tire with the heavy weight of them . thanks
