Expert Answers about Tire Inflator

• Should Trailer Tires be Inflated When they are Hot After Driving or Cold Before
• With trailer tires you want to inflate them to the max psi listed on the sidewall before driving warms them up. So whatever the ambient temperature is outside basically.

• Replacement Axle for 1981 Wells Cargo Enclosed Trailer That Shows Uneven Tire Wear
• Uneven tire wear can indicate any of several problem conditions.

If it wears more in the middle than on the sides this indicates over-inflation. If the two tires on an axle both have more wear on the inside edges of the tread then this usually signals that the trailer has been overloaded. A bent spindle is of course another possibility.
