"When I purchase a set of Studdable Winter / Snow tires, will they arrive studded or unstudded?" All studdable winter tires we sell can be sent with or without studs installed. It's important to note that only new tires that have never been driven on can be studded. Tires already driven on cannot be studded nor re-studded.
Studdable Winter / Snow tires without studs are still effective winter tires and many drivers choose not to stud them. If you desire a higher level of traction due to challenging conditions, studs can be added to any tires in this performance category for a $15 charge.
When placing your order online, simply check the box to add studs when prompted in the checkout. Because studdable tires are manufactured with different tread depths, studs are manufactured in different lengths that must be matched to the depth of the holes molded in the tire. We will select the correct gauge of stud for your specific tire and ship them out with the studs pressed in.
A Studdable Winter / Snow tire's tread is often lubricated to facilitate stud installation, therefore a special tool is inserted into the molded hole, spreading the tread rubber, and inserting the stud towards the bottom of the hole and retracting. With the stud inserted, the tread rubber compresses around the stud's flat head and cylindrical housing to hold it in place. Because it takes some time for the lubricant to evaporate and the tread rubber to securely compress around the stud, new studded tires require a break-in period.
Some states prohibit studded winter tires completely or restrict them to seasonal use. Check with local law enforcement officials to confirm restrictions in your area.
