Product Details

This listing is for one BFGoodrich All Terrain T/A KO3 tire, size 37x12.50R18 with a load index of 128R. This tire is built for drivers who want a capable tire for both on-road driving and off-road adventures.

The All Terrain T/A KO3 features an updated tread design that BFGoodrich says offers improved wear life and better traction in various conditions compared to previous models.

You may also need to consider potential modifications for proper fitment, such as fender trimming or suspension lifts, depending on your specific vehicle. Always consult your vehicle's manual or a qualified mechanic to confirm compatibility and any necessary adjustments before installation.
