Toyota is infamous for offering special, nerfed versions of well-known tires on their new vehicles. You buy a Tacoma, you don’t get the Wildpeak AT4W, which is a very good all terrain tire. Instead, you get the Wildpeak AT4WA, which is a nerfed version with reduced tread depth that is quieter and more efficient than the real AT4W but less capable and wears out faster.
