Customer Reviews
I recently put these on my Gen 3 Tacoma. Previously, I had an aggressive mud-terrain tire. These are noticeably quieter -- by far! They provide a smooth ride with confident maneuvering. The majority of the miles on these tires are highway and city. However, I just returned from an adventure that included torrential rain, extremely rocky and muddy roads, and river/stream crossings. The tires performed well over the various terrain. (I scored the tread life a 4, as I don't have enough miles to make a definitive determination.)
⭐⭐⭐⭐⭐ Outstanding Tires and Excellent Customer Service! I couldn't be happier with my experience at Discount Tire in Fort Myers, Florida! I purchased a set of Toyo Open Country A/T III tires, and they have been an excellent choice. Great-looking tires with an aggressive tread design, a smooth, comfortable ride, and excellent handling both on the highway and in different road conditions. The customer service at Discount Tire was outstanding! The staff was professional, knowledgeable, friendly, and made the entire experience easy from start to finish. They really know their products and take pride in making sure their customers are satisfied. It's refreshing to do business with a company that values quality products, fair prices, and great customer service. I highly recommend Discount Tire in Fort Myers and the Toyo Open Country A/T III tires! Five stars all the way!
Great tires will be getting these on my next truck as well. Pull my bass boat a lot and the tires hold up well for towing.
