Are studded tires legal in Texas?

Texas law sets no seasonal dates for studded tires. Texas law bars non rubber protuberances such as studs unless they do not injure the highway, and it sets no date window. Tex. Transp. Code § 547.612 reads: "(c) A tire used on a moving vehicle may not have on its periphery a block, stud, flange, cleat, or spike or other protuberance of a material other than rubber that projects beyond the tread of the traction surface, unless the protuberance: (1) does not injure the highway; or (2) is a tire chain of reasonable proportion that is used as required for safety because of a condition that might cause the vehicle to skid."

Texas law sets no start or end date, so the conditions in the statute apply all year. A stud or other non rubber protuberance is allowed only if it does not injure the highway.

A stud or other non rubber protuberance is allowed only if it does not injure the highway.

Tire chains of reasonable size are allowed when needed for safety because of a condition that might make the vehicle skid. The statute reads: "(2) is a tire chain of reasonable proportion that is used as required for safety because of a condition that might cause the vehicle to skid."
