I'd find another tire shop. Mine balanced out well, with minimal weight needed. Just find someone who knows what they are doing. Very happy with the tires. In the mean time I sold that truck and bought a 2014 roush SCREW and in 2 weeks will be going back to the 37 KO2s again. Great all around tire (i.e. you need something for snow) for everything except mud, and great longevity.
