OK I have a Cub Cadet mower that is a few years old but runs great. My trouble is the tires on it are cracking in the sidewalls. Cracking is getting so bad they are leaking air. Tread is not bad. Tubeless tires. My thought_ Buy some tubes to put in them and see if they will outlast the mower?? Or go ahead and find some tires? These stupid things cost almost as much as a car tire!!! Tubes can be had for less than 1/2 what tires will cost me. Just wondering if anyone had tried anything like this. Will the tubes just pop or would they last a few years like that? The mower is a 50 inch cut, runs great, uses no oil. Tubes or Tires???
