The quietest 285/60 R20 tires are labelled at 73 dB external noise:
Label values come from the EU EPREL database and apply to the EU market versions of each tire. Wet grip and rolling resistance run from class A (best) to E; noise is the measured drive-by figure. A good label is a floor, not a verdict - the tests and owner ratings above tell you far more.

Figures are calculated from the nominal size. A loaded, rolling tire runs a few percent smaller, and true widths vary slightly between makes.
The most recent owner reviews fitted in this size, in their own words.
These tires ride extremely well on 1/2 ton. If you are in a very dry climate (desert southwest) they will serve you well. The ride is very good, quiet, and smooth on pavement. Very good for light to medium off-road trails and farm. Where the Recons fall short is wet traction and braking as well as snow and ice. The Recons balanced easily with less than 15 pounds of road force and less than 3oz on each wheel.
Final thought: A great buy if you are in a dry climate. For wet/snow, look elsewhere.
2025 Sierra 1500 AT4, LT285/60R18. Unfortunately it took 78 pounds of road force to balace one of the tires and 53 for another. I hhave the KO3s on a 2007 FJ Cruiser and live them on that ride. I would avoid the KO3s on most LTs. Over 50 MPH they hop, shake the steering wheel, and bounce the bed. Returning them under Michelin/BFs 30 day satisfaction policy. Switching to the Toyo Open Country AT III.

Owner ratings are submitted through the review form on this site, naming the tire, the size and the distance covered, and are checked by hand before publication. Test results come from independent published tire tests indexed by size, and label values from the EU EPREL database.
The Tire Reviews Score rates each tire out of 10 using independent test results and the full body of owner reviews, so you can check a car-specific ranking against the wider evidence.
Every test published as a Tire Reviews test is run by Jonathan Benson, who has been testing tires independently since 2007.
