Goodyear Marathons were known to do that. I lost a few fenders with them. I now replace trailer tires every 5 years regardless of mileage. That one looks old. Consider yourself fortunate.
I suggest you replace with 65 psi, 85 mph rated Goodyear Endurance, Carlisle Radial Trail, or Maxxis 8008.
Very true! Nobody want to spend the Money, when a Tire looks good! We're Human! We like to Save Money, but the Fact of the Matter is, when a tire gets older than 5-6 yrs.
Replace it, as age, weather Time, Sun, etc...........................Tears Tires apart!
Each tire has a Born on, mfg. code to tell when it was made. Do your homework, research and don't rely on Luck!
I needed to take my 20 ft. enclosed trailer on a long trip recently, and replaced all 4 tires with new ones including the brand new spares,(2).
Crazy, maybe, but I didn't have any problems!!!!!!!!!!!!!!!!!!!!!!!!
It's called Cost of Living! And it ain't cheap!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
