Wheels

Wheels come in many different designs and usually fall into two categories: stamped sheet metal and machine castings. Some wheels are a combination of the two. Usually cast alloy wheels are higher priced, but have greater strength than stamped sheet metal wheels. Stamped sheet metal wheels are the most common, because they are less expensive to produce and are adequate for most uses. Some cars have wire wheels which consist of three basic components; inner rings, outer rings, and a series of spokes which connect the two. Cast aluminum wheels are very popular, magnesium wheels are also popular. Both are popular because they are light-weight and strong.

When The Car Doesn't Work

BEFORE a car needs repairs, the owner should check the car's manual to see if maintenance is needed. Failure to care for the car, and ignoring the initial warning signs (funny noises, problems that "fix themselves", etc) will produce more extensive and costly damage in the long run. I. Starting Problems Problems encountered in starting are usually due to the condition of the battery (clicking noises, no sound or slow grinding). These problems can often be solved by jump starting or charging the battery. If there is no response after trying these cures, it will probably be necessary to get experienced help or have your car inspected and serviced by a professional. II. Moving Problems 1. Problems with the engine hesitating, cutting out, being weak, or having difficulty with the idling should all be carefully inspected by an experienced mechanic. Overheating may be due to a need for additional coolant in the radiator or a need to unload excess weight (as when pulling a trailer). Turn off all accessories; i.e., the air conditioner. If this doesn't help, get professional help. 2. Transmission problems should always be inspected for repair or adjustment by a professional mechanic. If the car is driveable, drive slowly and carefully to the nearest service facility. If in doubt about driving the car, call a tow truck. III. Stopping Problems: When the brakes fail to hold, or if they squeal, grab or drag, they should be inspected and cared for at a specialized brake shop. When the problem is due to worn tires, the tires should be replaced at once before damaging other, more expensive elements of the car.
