Our tires are guaranteed to be free from defects in workmanship and materials for the life of the tread. Adjustment is made on a prorated basis (you pay for tread wear used). We are not responsible for tire and tube failure due to improper mounting, mechanical failure or improper alignment of the vehicle. Coker Tire does not offer any guarantee of fitment for any particular purpose and limits its liability to the purchase price of the item. All tires and tubes should be installed by properly trained individuals. Dimensions for tires listed are not scientifically measured and may vary depending on rim widths and inflation.
