The motivation for choosing tires and rims there are many. Many prefer the aesthetic factor - usually low profile tires with larger rim more stylish. But do not forget to also factor in performance, safety, comfort, and also cost no less important.
Here are some tips on choosing a good rims and tires:

1. Make sure the tire and rim size right
Tire sizes must conform to the specifications usually train carriage designed for rims and tires size slightly larger than the standard.
Check the vehicle manual. If the size of the rim and the tire is too large, there is a possibility touched during the lull when the car passed the 'bump' large, or when carrying passengers and goods in full. Usually if the standard size is 15 inches, two larger sizes (16 and 17 inches) can be used.
Similarly tire size must be appropriate to the size of the rim, not only in terms of the internal diameter, but also the width of the tire. Refer to the manufacturer's standard tires or tires as standard association ETRTO (Europe) or JATMA (Japan).
If the width of the tire is too big or small for the size of the width of the rim, the tire perishable risks will be greater.
Size is not limited to the rim diameter alone. Take into account also the rim offset (how far away the surface of the hub to the rim of the tire center line), which is usually determined by the car manufacturer.
For example, if the standard design for the rim of a vehicle model is 42mm, it is better if the offset is maintained when replacing a new rim.
Offset is closely related to the steering axis, bearing resistance at the hub, brake systems and thus has many associations with various aspects of the car's performance and should not be underestimated.
Rim and tire combinations also determine the total weight of the wheel that is not less important to the acceleration performance and fuel consumption, as well as ride comfort.
So you must not wear big rims cheap then complain car accelerates and strong moist eat oil.
There is also a luxury model car that wears the tires 'run flat' or 'extended mobility', which allows the car driven even the tires lose pressure.
These tires are very expensive, but the upside is that using a car tire model is not equipped with a spare tire, thus decreasing the weight of the load and boot space is larger.
2. Make sure the tires perform in accordance with the type of drive
Tires like other car components consist of a variety of performance ranges - from V-rated tires for high speed and maximum grip, to which interest is durable tires (but loud, noisy and less grip).
There is also a focus on the performance of the tire wet road, and which are designed to reduce fuel consumption (low rolling resistance). Whatever does your homework and make sure they are suitable for your use. Do not focus on any one aspect alone, because usually there's another aspect that will be compromised.
Among the factors to be taken into account performance:
- Maximum grip - tires for track-day use have a good grip but may only last only 20-30 thousand km. Usually this type of tire has a speed rating of high (Z or V-rated), the surface of interest is almost full (less groove or drain so good for maximizing the flow of air- dry grip), and a soft rubber compound
- Wet road performance - Tires that have flowers that help perk water more efficiently stable in wet road conditions by reducing the likelihood of 'aquaplaning' - a situation where the tires 'floating' because the layer of water trapped under the tire tread at high speed in wet conditions. Wet performance is also good for the type of tire that has a mixture of silica in the tread compound.
- The level of NVH tire - less noisy because of the type of tire type compounds and treads design that may have a resonant sound at a certain velocity. It is also closely related to the ride comfort - noisy tires are usually uncomfortable being driven on uneven surfaces. Make sure the tires are selected according to the desired level of NVH.
- Long tire life expectancy - be careful with the promise of a long life of the tire because the tire possibilities like this using compound interest harsh and high performance that may reduce traction and feedback to the steering wheel.

Make sure the tire and rim high quality
Frugal attitude good attitude, but for tire and rim usually too frugal attitude can be a dangerous thing.
Again, tire and rim is a single component that holds all the power of turning, braking and accelerating the vehicle. Bring out a little shopping to buy branded tires and rims. Especially in improving labor market conditions are fulfilled brands whose products are cheaper doubt in terms of quality.
Also avoid buying a used tire and rim. Back tires sometimes shaded flowers sales of one side of the law. While the rim has been used sometimes deformed, and there are also those who have more holes punched hub for PCD (Pitch Circle Diameter) vary.
This is very dangerous because it can weaken the structure of the rim is important.
After a set of tires and rims are fine-tuned with the use of selected, then make sure that the installation process is done well.
Make sure the tires are installed in accordance with the position of the rim (see red dots and yellow on a tire - make sure the installation is aligned with the white dot on the rim) to reduce vibration during the spinning wheel.
Tire and rim should be set at the correct pressure cold wind (check if there is difference in the tires front and rear), and then inserted into the machine counterweight to offset the weight of the metal.
Ensure that the correct weight metal used in lip rim and inner rim and glued it perfectly so as not dated.
Some sophisticated balancing machine can determine the position of the corresponding wheel on the car (front / rear and left / right) according to the rate of lateral force (lateral force) that can minimize car pulling to the left or right.
Through the tire and rim, there are four places you in contact with the road cars, each of the palms. Tire and rim combination and its importance for the performance and safety of the car cannot be seen easily.
