A 37×13.50R24 tire is 37.0″ tall and 13.5″ wide, and fits a 24″ wheel.
Heights published by Mickey Thompson and Toyo for all 3 tires in this size. Their published revolutions per mile work out to 35.4–36.0″ under load (below).
Real 37×13.50R24 tires measure 36.53–37.01″, against 37.00″ from the size code. They run both taller and shorter than the size code.
Published revs per mile (561–569) mean the tire rolls like a 35.4–36.0″ tire on the vehicle. Use this for speedometer calibration.
The lightest (Toyo Open Country R/T Trail, LT F) is 8.9 lb lighter per corner than the heaviest (Toyo Open Country M/T, LT E).
