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
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
For motorists who drive a car with a Multi Information Display (MID) device can easily monitor the use of fuel. Then, how about the MID figures show that wasteful fuel usage? Least wasteful fuel consumption also depends on driving style, technical factors other than mechanical course.
Here are some tips and tricks that need to be done to reduce fuel budget:
- Do not stomping.
Pedal must be stable and gradual. If you step on the gas pedal abruptly, auto fuel that will be sucked into the combustion chamber is also growing. Meanwhile, at that time was still low engine rpm. Consequently not all that fuel into the engine room fire. Which is called a waste. Because no fuel coming out in the form of energy, but go wasted through exhaust.
- Discover the engine RPM.
One way to make an efficient fuel consumption is to change gear (transmission) the right, which is when the engine reaches maximum torque (maximum moment).Gearshift when cars were in need of torque (thrust force), should be conducted with respect to information about the maximum moment (maximum torque) of each car (usually in units of kgm / rpm). Meanwhile, if the vehicle is moving (where the thrust is not needed), the most efficient when driving with the RPM between 2500 until 3500 and with the highest gear.
For example, technical data on the manual written book Maximum torque: 200Nm/3750rpm. This means that the highest moment of 200Nm occurs at the time of rotating machines as much as 3750 per minute.
In this example, means that we should make the shift gear when the figure shows the range of 3750 rpm. Figures can be viewed at RPM tachometer located on the dashboard of a car.
Figures RPM on tachometer very important note. To streamline fuel consumption, while speeding down the road. Keep the engine speed at the maximum torque range. Because, that’s when fuel supply is in accordance with the output from the machine.
One habit that is often overlooked driver is: do not immediately adjust the gears after lowering speed (deceleration). After running hard and then suddenly put the brakes suddenly, you should also pass the shift gear to a lower position.
- Measure the HC and CO.
Whether or not extravagant consumption of fuel is also determined by engine components. Machine components that have a lot of wear / damage can cause incomplete combustion processes.To detect it, check the exhaust emissions. If the examination results show the value of HC (hydrocarbon) and CO (carbon monoxide) is too high, this is a sign of combustion in combustion chamber is not perfect (lots of wasted fuel).
- Expenses and Activator.
Another factor that determines the fuel consumption is a load and drive (drive vehicles). Increasingly heavy burden to be transported, their consumption will also increase. The definition of driving include: couplings, bearings (wheel), coupling (propeller shaft), axles, and wheels.
When these components worn or damaged, would cause loss of power generated by the engine to push the car running. Meanwhile, fuel consumption remains large. Related to the wheels, use of large tires and wheels, including the factors that affect fuel consumption.
Here, other tips are also noteworthy:
- Habits out of the office lunch / evening, preferably reduced. Bring lunch / delivery seemed better.
- If traveling, take the family / colleagues that one purpose / intention to go together in one car. For the same matters do not necessarily have to run two or three vehicles while with one unit will suffice.
- Switch to public transport such as busways, railway, or metrominis.
- When a traffic jam, while out of town, you should stop first. Changing other activities such as rest, eat, go to the bathroom, or fill the fuel to decompose congestion.
- Drive gently. Reduce the frequency of braking. When facing a red light does not need to step on the gas, let the car slide because they must be stopped. Reduce the frequency stepping on the gas and brakes. This is the step energy disposal in vain.
- When sliding or decreased, gear should not be positioned at neutral. Engine brake effect proved more economical fuel than stationary.
- Turn on the AC as needed.
- Ask workshop setting appropriate timing according to the type of fuel used. Ignition point too forward or backward resulting wasteful of fuel.
- Clean the air filters (can be done by yourself) per 2500 km, or depending on conditions.
- Do not heat the car for too long, maximum 2 minutes. Warming-up machine for 30 minutes, synonymous with traffic for 30 minutes as well.
- Find the route / alternative road is not jammed, out a little with the current path is more save.
