An equivalent size is a tire whose overall diameter stays within 3% of 185/45R15, so the speedometer, gearing and wheel-well clearance stay close to what the vehicle was designed for. People look for one when 185/45R15 is scarce or expensive, or when they want a different width or rim size. An equivalent size is not an automatic swap, and we do not guarantee that it fits your vehicle: check the rim width range, make sure the load index is at least the original, and allow for possible rubbing.
