Those brand new Titans were put on my John Deere 2030 that I now use for bush hogging. The tires were loaded and the weight of the tractor would puncture the tires when I drove over cut brush stubble from a previous pass. It did it twice before I decided that I can't afford the repairs and sprung for the expensive PrimeX tires with steel belts. Never a problem again! Oh, by the way, I had similar problems with the front tires and I decided to go with the repurposed aircraft tires and new rims to accommodate their 18" rims. They've also held up well. Two good choices that I've never regretted, and they're still in use today - No Problems! (Just as a note: The PrimeX tires are loaded too!)
