11R22.5 tire size

Truck and trailer tire. 11R22.5 is 40.7 – 42.6 inches tall in manufacturer data books, measured on 24 tire models.

What 11R22.5 means

11-inch nominal section width, R radial, for a 22.5-inch 15° drop-center tubeless rim. No aspect ratio in the size: the height comes from the standard for this size.

Used on steer, drive and trailer positions — the tread pattern of the model decides the position, not the size.
