We contacted our friends at General Tire to see if they offered a trailer tire that would last more than 50,000 miles. Our inquiry was answered with a set of 285/85/R16 General TRs. These tires are super-durable with extra-deep tread blocks. The tread design is rated for mud and snow, yet features five semi-solid long wear ribs to help our trailer track straight as an arrow. They are load range E-rated and built from a cut and chip-resistant compound.
