The company announced additional sizes between its Cooper Discoverer® Rugged Trek™ and Discoverer® STT Pro™ lines at SEMA 14

Designed for raised pickup trucks, these all-new, full-size tires have a signature Cooper knife edge and Mountain Pass customizable sidewall designs and will be available to consumers in early 2023.

“While Cooper currently covers the vast majority of mud terrain tire sizes on the market1Tire enthusiasts now have an even larger, stronger tire range to help them travel off-road with confidence and stylize their vehicle,” said Michael Kramer, managing director of product marketing at Goodyear. “The expansion of the line to include more enthusiast sizes is a direct response to the success of the Cooper Discoverer® Rugged Trek™, which has received overwhelmingly positive feedback from consumers.”
