A tire's speed rating
indicates the optimal speed that the tire can safely maintain over time. In short, it's the fastest speed a tire can handle before it no longer performs as designed. ... A tire's certified speed rating is given a letter from A to Z, ranging from 5km/h (3mph) to above 300 km/h (186 mph).
Tire Speed Ratings, Explained
My Carlisle load range D are rated 81 mph. I have no intention of towing at that speed.
