TRAILER GUIDELINES

Tires for light trucks have other markings besides those found on the sidewalls of passenger tires.

LT: The “LT” indicates the tire is for light trucks or trailers.

ST: An “ST” is an indication the tire is for trailer use only.

Max. Load Dual kg (lbs) at kPa (psi) Cold: This information indicates the maximum load and tire pressure when the tire is used as a dual, that is, when four tires are put on each rear axle (a total of six or more tires on the vehicle).

Max. Load Single kg (lbs) at kPa (psi) Cold:This information indicates the maximum load and tire pressure when the tire is used as a single.

Load Range: This information identifi es the tire’s load- carrying capabilities and its inflation limits.

Tire Safety Tips

Slow down if you have to go over a pothole or other object in the road.

DO NOT run over curbs or other foreign objects in the roadway, and try not to strike the curb when parking.

Check tire inflation pressure weekly during use to insure the maximum tire life and tread wear.

DO NOT bleed air from tires when they are hot.

Inspect tires for uneven wear patterns on the tread, cracks, foreign objects, or other signs of wear or trauma.

Remove bits of glass and foreign objects wedged in the tread.

Make sure your tire valves have valve caps.

ALWAYS check tire pressure on tow vehicle and trailer before towing. Check tire pressure at least once a month.

DO NOT overload tow vehicle. Check the tire information and loading placard for safe allowable tire loading conditions.

Tire Repair

The proper repair of a punctured tire requires a plug for the hole and a patch for the area inside the tire that surrounds the puncture hole. Punctures through the tread can be repaired if they are not too large, but punctures to the

sidewall should not be repaired. Tires must be removed from the rim to be properly inspected before being plugged and patched.

Replacing Worn or Damaged Tires

Replace the tire before towing the trailer if the tire treads have less than 1/16 inch depth or the telltale bands are visible. Check inflation pressure weekly during use to insure the maximum tire life and tread wear. A bubble, cut or bulge in a side wall can result in a tire blowout. Inspect both side walls of each tire for any bubble, cut or bulge; and replace a damaged tire before towing the trailer.

Table B below will help pinpoint the causes and solutions of tire wear problems.

Table B. Tire Wear Troubleshooting

Wear Pattern		Cause	Solution
	Center Wear	Over inflation.	Adjust pressure to particular
			load per tire manufacturer.
	Edge Wear	Under inflation.	Adjust pressure to particular
			load per tire manufacturer.
	Side Wear	Loss of camber	Make sure load does not
			exceed axle rating.

WARNING

ALWAYS wear safety glasses when removing or installing force fitted parts. DO NOT attempt to repair or modify a wheel.

DO NOT install an inner-tube to correct a leak through through the rim. If the rim is cracked, the air pressure in the inner tube may cause

pieces of the rim to explode (break off) with great force and cause serious eye or bodily injury.
