Customer Reviews
While I like Toyo products, getting the $100 rebate from them has not happened. Any help would be great.
Some off-road. A little more noticable road noise than my BFG KO2s but definitely a better ride and traction in the rain! 2019 f150 3.5 Ecoboost. 275/65/18
Great tires all around.
