Three Misunderstandings of Low Bed Trailers

In daily use, many low bed trailer operators have misunderstandings about tire pressure, oil filling, belt tension and wheel bolt tightening. These wrong habits will accelerate parts wear, affect safety and reduce service life. Here are the three common misunderstandings and correct operation guidelines.

Misunderstanding 1: Higher tire pressure means better overload capacity and fuel economy
 

Excessively high tire pressure reduces the tire contact area with the ground, accelerates tread wear, weakens braking performance, and threatens driving safety. Too low tire pressure causes faster shoulder wear and higher fuel consumption

Correct practice: Inflate strictly according to the factory-rated pressure marked on the trailer body.
 

Misunderstanding 2: More engine oil is better
 

Overfilling crankcase oil increases crankshaft rotation resistance, causes more oil splashing on cylinder walls, increases carbon deposits, reduces engine power and worsens emissions.

Correct practice: Check with the oil dipstick. Keep the oil level between the upper and lower marks, ideally in the middle.

Misunderstanding 3: Accessory belts and wheel screws should be as tight as possible
 

An over-tight accessory belt overloads bearings, shortens part life and may break suddenly. Wheel bolts must be tightened to the specified torque; both too loose and too tight are dangerous.

Correct practice: Use a torque wrench to tighten according to standard torque values. For low bed trailer wheel bolts, the standard torque is usually 100–130 N·m.
 

Correct Use & Maintenance Summary
 

Follow standard operation and regular maintenance to ensure low bed trailer stability, safety and long service life.
