Replace OEM tires with 2 years life left?

Personally.......I’d replace with a tire of good reputation. Many tires that fail, shown “zero” outward signs of impending failure.....belt “slippage” is not always readily apparent with a visual inspection! Many years ago, I observed a some old tires the had increased it’s circumference by over 6”, without a tape measure.....you would not have known. It took me a while to determine why the tires( multi-axle trailer) we’re contacting each other. I initially thought that I had a suspension failure. Nope......just tires getting much larger! memtb
