speeds in excess of 65 mph may be required, then the following
adjustments or recommendations should be followed:
•At speeds from 66 mph through 75 mph, cold inflation pressure must
be increased 10 psi above the recommended pressures for the load
being carried.
• Do not exceed the maximum inflation pressure of the wheel (all wheels
have maximum allowable inflation pressures).
REPLACEMENT TIRES FOR LIGHT TRUCKS – P-METRIC VS .
LT-TRUCK
Tire installers should exercise extreme caution when replacing tires on
light trucks.
The maximum load capacity stamped on the sidewall of a P-metric tire is
reduced by a factor of 1.1 when used on a light truck, a sport utility
vehicle, or a trailer.
WARNING!
•P-metric and LT-metric tires are not necessarily interchangeable.
P-metric and LT-metric tires follow completely different Load/
Inflation tables and are designed to carry different loads at
different pressures.

WARNING!(Continued)
•LT-metric tires carry their load at higher inflation pressures and do
not always have adequate load capacity to replace P-metric tires of
the same size.
• After reducing a P-metric tire’s load rating by dividing by 1.1 for
fitment on a Light Truck, the P-metric tire may not offer sufficient
load capacity to replace an LT-metric tire of the same size.
• Contact your Toyo Tires dealer or Toyo Tires Technical Service for
help determining how to choose a proper replacement size.
• Driving with underinflated or overloaded tires may result in
immediate tire failure, which can cause an accident and could lead
to serious personal injury or death.
When a P-metric or metric tire is installed on a light truck (SUV, pickup,
minivan), the load rating is reduced by dividing by 1.1. (This load
reduction factor is prescribed by Federal Motor Vehicle Safety Standards
(FMVSS) and is based on the expectation that passenger-type tires may
experience more severe loading and usage conditions when applied to
light trucks.) For example, 305/50R20 has a maximum load capacity of
3086 lbs. If this tire is fitted to a light truck, the actual allowable load for
the tire is 2805 lbs. (3086 lbs. divided by 1.1).
