Hello. Have a 545 Backhoe and tires are really dried up. Still hold air but will go anytime. The tire size on the rear is 16.9-24. Is there any other tire sizes I can use on my backhoe. Found a guy with 17.5L-24 backhoe tires that are new but sat around for a few years. Will those work fine on my backhoe? And how long do new tires last if they sat around being unused. Also do you know if the 545 backhoe came with tubed or tubeless on the rear tires?
