“Part-worn tires” refers to tires that have been previously used and removed from another vehicle. These tires are then sold as second-hand or “used” tires.Overall, while part-worn tires may offer a cost-effective option for some drivers, it’s essential to carefully consider their condition, safety, and compatibility before making a purchase. In many cases, investing in new tires may be a better long-term option for ensuring safe and reliable performance on the road.
