TIRE INFORMATION

Tire Terminology Glossary

???Accessory weight means- the combined weight of automatic transmission, power steering, power brakes, power windows, power seats, radio, and heater, to the extent that these items are available as factory-installed equipment.

???Carcass means- the tire structure except for the tread which provides the major portion of the tire???s capability to deflect

in response to the vertical loads and tractive forces that the tire transmits from the roadway to the non-pneumatic rim, the wheel center member, or the vehicle and which attaches to the vehicle or attaches, either integrally or separably,

to the wheel center member or non-pneumatic rim.

???Carcass separation means- the pulling away of the carcass from the non-pneumatic rim or wheel center member.

???Chunking means- the breaking away of pieces of the carcass or tread.

???Cracking means- any parting within the carcass, tread, or any components that connect the tire to the wheel center member.

???Curb weight means- the weight of a motor vehicle with standard equipment including the maximum capacity of fuel, oil, and coolant, and, if so equipped, air conditioning and additional weight optional engine.

???Load rating means- the maximum load a tire is rated to carry.

???Maximum loaded vehicle weight means- the sum of:

a.Curb weight;

b.Accessory weight;

c.Vehicle capacity weight; and

d.Production options weight.

???Maximum tire width means- the greater of either the linear distance between the exterior edges of the carcass or the linear distance between the exterior edges of the tread, both being measured parallel to the rolling axis of the tire.

???Normal occupant weight means- 68 kilograms times the number of occupants.

???Occupant distribution means- distribution of occupants in a vehicle.

???Production options weight means- the combined weight of those installed regular production options weighing over

2.3 kilograms in excess of those standard items which they replace, not previously considered in curb weight or accessory weight, including heavy duty brakes, ride levelers, roof rack, heavy duty battery, and special trim.

???Tread means- that portion of the tire that comes in contact with the road.

???Tread separation means- pulling away of the tread from the carcass.

???Vehicle capacity weight means- the rated cargo and luggage load plus 68 kilograms times the vehicle???s designated seating capacity.

???Vehicle maximum load on the tire means- that load on an individual tire that is determined by distributing to each axle its share of the maximum loaded vehicle weight and dividing by two.

???Vehicle normal load on the tire means- that load on an individual tire that is determined by distributing to each axle its share of the curb weight, accessory weight, and normal occupant weight and dividing by 2.

???Section width- This number gives the width of the tire in inches. The larger the number, the wider the tire. (The markings on the example tire diagram show 4.80. The markings on your tire may differ.)

???Inner diameter- This number gives the inner diameter of the tire in inches. This is also the rim diameter in inches. (The markings on the example tire diagram show 12. The markings on your tire may differ.)

???U.S. DOT tire identification number- This begins with the letters ???DOT??? and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code where it was manufactured, and the last four numbers represent the week and year that the tire was built. For example, the numbers 2107 mean the 21st week of 2007. Any other numbers used are marketing codes used at

the manufacturer???s discretion. This information is used to contact consumers if a tire defect requires a recall.

???Maximum Load Rating- This number indicates the maximum load in kilograms and pounds that can be carried by the tire.

Load Index Rating Codes

???Load index- This is a measurement of how much weight each tire can support. See chart above. (The markings on the example tire diagram show 71. The markings

on your tire may differ.) Note: You may not find this information on all tires because it is not required by law.

Tire Speed Rating Codes

???Speed Rating- The speed rating denotes the speed at which a tire is designed to be driven for extended periods of time. This does not indicate that the vehicle or rims can safely reach or maintain that speed. These ratings are listed to the right. (The markings on the example tire diagram show M. The markings on your tire may differ.)

Note: You may not find this information on all tires because it is not required by law.

???Tire Ply Composition and Materials Used- The number of plies indicates the number of layers of rubber- coated fabric in the tire. In general, the greater the number of plies, the more weight a tire can support. Tire manufacturers also must indicate the materials in the tire, which include steel, nylon, polyester, and others.

???Maximum Permissible Inflation Pressure- This number is the greatest amount of air pressure that should ever be put in the tire under normal driving conditions.

1.Using a suitable solvent, thoroughly clean the bearings and the rest of the parts in the Hub assembly of all grease, dirt, metal shavings, or any other foreign object. The parts must be cleaned even if they are new or clean.

2.Allow all pieces to dry completely.

3.Make sure that your hands are thoroughly clean and the bearing packer (not included) is also thoroughly clean.

4.Place fresh, clean bearing grease in the packer.

5.With the grease-filled bearing packer in one hand and the bearing in the other, press the bearing into the grease, forcing the grease inside the slots in the bearing, continue doing this until every slot in the bearing is completely full of grease.

6.Finish assembling the hub/wheel assembly as explained in the manual, being careful not to get any dirt or debris on any part of the assembly.

Checking Tire Pressure

Note: Underinflated tires can decrease handling, stopping performance, traction, tire life, and load-carrying capability, in addition to

causing other negative and hazardous effects, including tire failure. Overinflated tires are

at greater risk of an impact break, where the tread and casing break when striking a hard edge, often opening a huge gash across the tread. Incorrect inflation pressure also increases tires wear rate. Therefore, it is important to keep tires inflated properly.

Check all tires??? pressure at least monthly, due to the following factors:

???Most tires naturally lose air gradually.

???Tires can suddenly lose air if the tire strikes a pothole, curb, or other object.

???It is usually not possible to determine underinflation of radial tires by visual inspection.

This vehicle has 60 PSI recommended cold tire inflation pressure. The term ???cold??? in this manual does not refer to the temperature outside, but it refers to the fact that a tire that has not been driven for a period is cooler (and therefore has lower pressure) than a tire that has been driven on. Tires heat up while being driven on.

To check (or fill to) a tire???s cold inflation, the tire must have not been driven for more than a mile or two for at least three hours. If you check a tires pressure when it is not ???cold???, the pressure will appear higher than the actual cold tire inflation.

Steps for Maintaining

Proper Tire Pressure

1.Locate the recommended tire pressure on the vehicle???s tire information placard, certification label, or in the owner???s manual. This trailer has 60 PSI recommended cold tire inflation pressure.

2.Measure and record the tire pressure of all tires.

3.If the tire pressure is too high in any of the tires and the tires have not been driven for at least three hours, slowly release air by gently pressing on the tire valve stem with the edge of your tire gauge until you get to the correct pressure. If the vehicle have been driven within the past three hours and the tire pressure is too high on any tires, then recheck the pressure once the tires have been allowed to sit motionless for at least three hours.

4.If the tire pressure is too low, note the difference between the measured tire pressure and the correct tire pressure. These ???missing??? pounds of pressure are what you will need to add.

5.At a service station, add the missing pounds of air pressure to each tire that is underinflated.

6.Check all the tires to make sure they have the same air pressure.

7.If the tires??? pressure was not measured ???cold???, then the pressure should be rechecked

with the tires cold as soon as possible.

To maintain safety, only purchase new tires of the same size as the original tires. Look at the Tire and Loading Information Placard, the Specifications

Chart in this manual, or the sidewall of the tire being replaced. If you have any doubt about selecting the correct size, consult a tire dealer.

Tire Tread

The tire tread provides traction that prevents your vehicle from slipping, especially if the road is wet or icy. Tires are unsafe and should be replaced when the tread is worn down to 1/16???. Measure tread depth using

a tread depth indicator (not included).

Tire Rotation

Every 5,000 miles the left and right tires should be switched. This will cause the tires to wear more evenly and last longer.

The tires need to be balanced to prevent vibration when driving. This involves attaching small weights to the rim to offset small differences in rim and tire weight. The tires also need to be aligned properly. Alignment is the orientation of the tires to the road surface and their being parallel. This helps the tires to wear evenly, and provide better traction. Both tire balance and alignment require specialized equipment that is not provided with this vehicle.

Tire Repair

To properly repair a punctured tire, the hole needs to be properly plugged and patched from the inside of the tire. Tread punctures can be repaired if they are not too large. Sidewall punctures should not be repaired, the tire needs to be replaced if the sidewall is damaged. Tires should be removed from the rim to be inspected before being plugged and patched. A qualified mechanic should remove the tire from the rim, perform the repair, and remount the tire.
