Toyo Open Country M/T LT375/45R22 Tire
There is nothing subtle about a 14.8-inch measured overall width. This LT375/45R22 Open Country M/T is the 128Q load range F version, with a 35.6-inch measured diameter and 12.0–14.0-inch approved wheel-width range.
Open shoulder channels and hook-shaped blocks give it a purpose beyond parking-lot presence. Bring wheel width, offset, clearance and load requirements to the fitment check. The tape measure gets a vote.

Fitment & Installation
Match tire size, load and speed ratings, wheel diameter, width and capacity to the vehicle requirements. Check body, suspension and brake clearance through steering and suspension travel. Have a qualified tire professional mount, balance and set cold inflation for the actual vehicle and load. Listed maximum pressure is a tire limit, not the recommended everyday setting. Ask POR to help check the complete setup before ordering. Larger tires or a suspension lift can change handling, increase braking distance and increase rollover risk. Follow vehicle and tire-manufacturer guidance.
Safety & Use
Underinflation, overloading, damage or improper installation can cause tire failure, loss of control, serious injury or death. Do not drive on a damaged tire. Follow Toyo’s safety manual and the vehicle manufacturer’s instructions.
