The product is a set of four Sumitomo studded winter tires with a rim diameter of 15 inches and an aspect ratio of 195/65R-15. These tires are mounted with hubcaps and are part of the Sumitomo Encounter product line. The studded design of the tires provides enhanced traction on snowy and icy roads, making them ideal for winter driving conditions.  I ran these from November to May one year only so they are practically new. Probably have 1000 miles on them. The hubcaps are chrome look and make them look sweet. These tires and wheels came off a Volkswagen Golf model so check for stud pattern and size carefully before purchase
