Affiliate disclosure

TreadGrade is operated by Three Pines Company LLC, Frankfort, Illinois.

Affiliate buttons are not configured. Tire-line pages do not show retailer links, and Three Pines Company LLC does not earn a commission from them. The slots for Tire Rack, SimpleTire, and Amazon exist in the site configuration and stay empty until an id and an https link template are added.

Grades, sort order, and which lines appear come from the NHTSA file. They are not arranged to favor a retailer. When a button is shown, the page says so next to the button and links here.
