Modification have not finished yet while the alloy wheels not changed. The more thin wall tires, the bigger alloy wheels, higher prestige.

This trend began to depart from the race that is quickly transmitted to the modification spaces. In the circuit, large alloy wheels with tire walls thin (low profile) and the tread width is very beneficial because car drivers become more agile and responsive on the corner.

Moreover, hardly changed the tire diameter, so no longer need to adjust the speedometer and odometer. Large wheels also appear to appear sporty and masculine. No doubt, the main factor driving this is the proliferation of this trend the community.

Changing the default factory alloy wheels (OE / original equipment) with a larger diameter is known as plus-sizing. In these terms then known repertoire of plus-one, meaning that adding one inch diameter alloy wheels from OE. Examples from a 16-inch 15-inch. Similarly plus-two, add two inches, from 15 inch to 17 inch, and so on.

Apparently according to Consumer Reports testing, consumer protection agency in the USA, plus-one proved to yield the greatest benefits in terms of Performance. Plus-two and so on just gives a little extra traction while driving comfort, hydroplaning resistance and traction dropped. Price to pay is also more expensive. So bigger is not always more profitable. Plus-sizing is not recommended for SUVs unless indeed an option from the manufacturer.

Therefore, if you’re satisfied with the handling and comfort driving your car, it would suggest to forget the plus-sizing. Faithful only with OE.

Risk Plus Sizing

If not, start by considering the risk. Tires with big wheels and low profile responsive ride on the road was smooth. Conversely hollow road / rough, the tire is not perfectly capable of damping. Driving so uncomfortable. Therefore the streets in this country still have to ‘understandable’, the most wise if plus-sizing, not too far from the OE tire size.
Not only eroded the level of driving comfort, plus sizing excess (plus two / three or more) also threaten the safety wheels. Consumer Reports Tests at plus-three plus two and end up with damage to wheels and tires.

Choosing Velg

If you know the risks, and remain ‘unwilling’ with OE tires, it was time to visit the tire store / modifier. They will offer wheels and tires that fit on OE tires. As a rule, the addition of 1-inch diameter alloy wheels, in the match by lowering the tire wall thickness of between 50-10 percent and the addition of the tire tread width of 10 millimeters. Make sure also speed rating and load rating of the new tires should be higher than the original tires. Please note, plus sizing tire diameters are always changing overalls. It is difficult to exactly match the OE. This will affect many things including the speedometer.

Check also the wheels are in the drill. Most wheels are made of aluminum or a mixture of aluminum and steel. The problem is their quality varies considerably. To check, start by asking how the wheels were made. Alloy forgings (forged wheel) the most powerful and most expensive. Pressure cast wheels are also sufficient, in addition to a stronger alloy wheels are also lighter than the print (cast wheel). This last alloy is made by flowing molten metal into molds.

After that check also his bolt pattern, does not fit with those of your car. So forget about the wheel-pit yearning heart that holes not match. Sellers may offer some kind of adapter that can outsmart the holes that do not fit this. Be careful, this second solution because this adapter will increase the tension in the bolts may loose when driving. Make sure the tires have offset the after-specification cars. Tire tread also peered stretchy whether grind liang ban.

Choosing modifier

Now check modifier that will change the tire. Choose which specialize in plus-sizing. Choosing an incompetent shop tire and wheel damage risk.

Make sure the warranty if not satisfied or no damage as the tire grinding wheel or speedometer screw hole.

Workshop is also equipped with a wheel aligned to prevent early tire wear. Similarly, the ability to adjust suspension system that must adapt to new legs

Water coolant is not replaced for a long time, the color of water in the reservoir will change from translucent green to brown and slightly turbid. What’s up? Her answers.

Engine coolant is not good used condition and began to cause rust in the coolant system. The solution must be drained and replaced with new ones. If allowed, the rust will spread to the cooling system and engine, the cost of the repairs made perforated bags.

Workshops are usually recommended engine coolant should be replaced every 2-3 years, although some are able to five years. Engine coolant is a mixture of water danethylene glycol. These chemicals are functioning so that coolant does not freeze, preventing the boiling water (boiling point reached 130 C) so as not to overheat quickly, and with other additives to prevent rust.

Engine coolant must also match the raw materials were highly diverse cooling systems, plus be able to transfer heat efficiently, prevent corrosion and provide lubrication to water pump baffle-insulator. When conditions are good, the color green.

Engine cooling system is built from a series of complex components and materials. Aluminum, cast iron, steel, stainless steel, copper, brass, rubber and plastics, is a constituent.

When two different types of metals contact with each other through the intermediary fluid will behave like battery acid, an electron-proton exchange. This is what triggers metal corrosion. Replacing the engine coolant on a regular basis to prevent excessive formation of acid in the engine cooling system while helping to reduce corrosion.

Ethylene glycol is a toxic chemical compounds. Just a little swallowed, can kill pets. Therefore suggested to replace the engine coolant in the workshop. Workshops will remove the old engine coolant, clean the engine cooling system and fill the new coolant.

In developed countries, many workshops have engine coolant recycling system. In this system, water is separated and channeled out, while its chemical compounds reprocessed.

Routine maintenance becomes an easy way to treat the cooling system. The simplest way, check the height of the liquid with a view of the tank. If less than the minimum limit, add a little water to exceed the minimum limit. Few months, attention radioator rubber cap. If damaged, replace it just take cheap investment for an expensive machine.

When a light gray or reddish brown, you take it easy because it means the engine is in good condition that fit the condition of the engine, ignition timing and engine settings.

When the end of the insulator, electrodes and spark plugs covered with black soot and combustion smooth and dry, you should immediately check the choke mechanism, the air filter and replace spark plugs if necessary. The possibility exists that does not fit with the spare parts. If ignored it will be wasteful fuel consumption, black smoke and difficult to start when engine cold.

Color slightly yellow edge insulation may appear light brown and green color usually indicates the possibility of gasoline or oil contaminated water or additives are less suitable. As a result, sluggish engine, slowly accelerates, breathing hard and explosive exhaust.

So be more frequent cleaning and caring for spark plugs. Since the spark plugs will support machine-groomed to work well. Clean the spark plug every 2500 km and have it replaced when it has covered 20 000 km

This means that drivers no longer have tired of stepping on the clutch to shift gears. On cars with manual transmission, to shift gears, the clutch must be pressed.

Another fact, of all the control systems should be operated driver’s car, the clutch is the most energy-consuming. In addition, the level of operation is also very high, especially when traffic jams or solid creep!

Easy out
Nevertheless, it turns out there are still many among us who still assume negative effect on the automatic transmission. It is also recognized by auto manufacturers. For example, if the strike, cars with automatic transmission can not be encouraged. If is often used in mountainous areas, brake quickly exhausted.

All the assumptions of the past. Now, more and more automatic transmission, the manufacturer provides the mechanics who have the ability to fix it faster if there is a problem. In fact, now there is also a general workshops that could deplete the entire automatic transmission fluid (ATF) in the transmission and then filled with a lubricant that really new and clean.

In the car now, especially the use of injection systems, when the battery is weak, then the machine will not start. Because the engine computer to get energy from the battery. Therefore, the position of manual and automatic transmissions the same!

Then, on the assumption that the automatic braking when the car drove lavishly in areas with many derivatives, ascertained, that the condition occurred because the driver was too relaxed, allowing the transmission to position “D” course. In fact, D is the highest gear.

Keep working
To reduce the workload of the brakes, the driver must use engine brake effect by using a lower gear. In this case, it could be “two” or if more steep and slippery, should be “L”. Same with low teeth, 3 or 2 on the manual transmission. As for acceleration, the driver should kick or step on the gas pedal down fast!

So, driving with automatic transmission that does not mean the hand does not work at all. At a certain field conditions, 3, 2, and L should be used. Hand still be active. Only the left foot is completely relaxed. No need to stampede the clutch at all. For example when the streets are declining or accelerated during the ascent!

In fact, the bad conditions, by releasing the brake pedal and transmission at the position “D”, the car can crawl without having to hit the brakes.

If you already taste the delicious automatic transmission, especially for those who drive themselves, often through a traffic jam, and have high mobility, they certainly will not want to go back to manual if you do not have to. In fact, they are willing to spend additional costs, both for the transmission of more expensive fuel consumption plus a little more than manual

In driving, there is the term “understeer” and “oversteer”. Maybe you have or have often heard these two words. Just like what the symptoms of a vehicle, perhaps you have not experienced it. Or if ever, perhaps because you do not feel it does not know which one over, which is under.

Well, to understand it, can see the explanation below. Also, how to cope when experiencing.

Understeer
Symptoms tend to car straight, although the steering has been deflected. Commonly known as skid traction because the front is missing. If this was a panic-drivers-especially large potential for harm because the car out of the road.

How to cope :

1. Immediately slowed until traction vehicle back.

2. Do not add spin the wheel, or brakes.

3. Cut down on the accelerator gradually.

4. Reduce the steering wheel rotation.

Oversteer
The opposite of understeer, the rear tires lose grip. Consequently, the stern of the car to shift or twist.

The cause, most commonly we do braking when turning. At that time, the weight moves forward so that makes the rear tires less grip on power. Another factor for turning the steering wheel abruptly.

The danger, the car can be out of control and collided with something from the side. Meanwhile, the sides are not protected as well as front or rear.

How to cope :

1. Do not brake.

2. Do not move the position of the hands on the steering wheel.

3. Make a counter-steering or “reply to” steering wheel with alacrity, but not excessive.

4. Cut down on the accelerator (for rear wheel drive car).

5. Add just enough pressure on the gas pedal (for the front wheels moving car).

6. Move your eyes to the point of going to the intended

7. Be prepared to return the wheel to its original position
