What does a T mean on tires?
When the letter T appears on a tire sidewall designation—such as in sizes starting with "TFS" or "P"—it stands for "Temporary," indicating that the tire is designed specifically as a compact temporary spare tire (often called a donut spare). Alternatively, when T appears in the speed rating code (e.g., 91T), it signifies that the tire is legally certified for safe sustained maximum speeds of up to 118 miles per hour under proper load conditions.
