Sometimes car owners are faced with the need to replace the wheels on their car with new ones. But one has only to come to the store, motorists are immediately lost, such a large assortment of wheels is presented in them. It is not possible to choose something specific. When choosing discs, you need to take into account a huge number of parameters. One of them is the diameter of the central hole of the disc. You can find out what it is, what it affects, what characteristics are better to choose for your car from this article.

What parameters do you need to know when selecting discs?

At first glance, it may seem that choosing a new wheel for your wheel is not difficult. But then you come across designations of the following type: 4108, 6S ET47, Dia 62.5, R17. Yes, it is in this form that all technical characteristics are indicated. Because discs have many parameters that you need to consider when buying. What are they ininclude?

• Disk type: cast or stamped.
• Mounting holes: number and diameter.
• Shape of hubs.
• Center hole (hub) diameter.
• Disc circumference diameter.

If these nuances seem redundant, then any wheel shop will be able to help you. If you want to understand all the details yourself, let's try to understand what the diameter of the central hole of the disk is. What is it?

What is the disc center hole diameter?

This is a hole in the middle of the disk, which, despite its apparent simplicity, determines many parameters of the car. In the list of wheel characteristics, it is usually marked as Dia or simply D. Do not confuse it with the designation of the PSD, which indicates the size of the mounting holes. The diameter of the center hole of the disc must exactly match the diameter of the seat cylinder on the hub. Often, the same discs are produced for several car brands at once, so before buying, be sure to check that this parameter complies with the manufacturer's technical specifications. The disc may not stand up properly, hold loosely, because of which you will constantly feel vibrations and uneven wheel travel. It is even better to buy original spare parts. If this is not possible, then carefully study the options for the size of the central hole. Normally allow 2-5mm deviation for cast rims and 0.01mm for stamped rims.

What parameters are affected by the center hole?

Manufacturers of modern rims are faced with a huge number of brands and models with different parameters. Naturally, it would be pointless and very costly to produce discs individually for each car. Therefore, companies take the path of least resistance: they produce wheels with the largest possible center hole. And this is not very good effect on the behavior of the car, especially at high speeds. What other parameters are affected by this hole?

• Uniform tire wear. Selecting a disc with the “wrong” center hole can result in uneven tire wear. Due to improper load distribution, the tread pattern can only wear out on one side, which will eventually affect other machine characteristics.
• Tire life. How much you can drive on a new set of tires also depends on the right choice. Properly selected rims increase tire life.
• Steering wheel life. If the car has developed a sufficiently high speed, and the DIA is chosen incorrectly, then the steering wheel starts to “beat”, which ultimately leads to its breakdown.
• Body vibration. If at speeds above 80 km / h your car began to “shake”, then most likely the problem lies precisely in the diameter of the central hole of the cast disk.

What should I do if the center hole of the disc is larger than the diameter of the hub?

All disc sellers recommend beforecheck them with a purchase by car, while it is advisable to drive them at least a short distance. It is even better to accelerate to a speed of 60-80 km / h in order to understand exactly how the new wheels behave. It is difficult to put discs with a central diameter smaller than the diameter of the hub on a car. Is it possible to install wheels with a larger diameter? Of course, it is best to choose a hole that is ideal for your car. If this is not possible, then you can install the so-called universal disk, with a large central hole. To do this, you need to purchase a set of adapter rings that will compensate for the difference between the hub and the disc. Take care that they are not damaged during mounting of tires and that they are always put back after a seasonal wheel change. When trying on discs, do not forget to check if there are rings on the hub from previous discs.

Pros and cons of enlarging the center hole

What does the central hole affect, and will the technical parameters of the car change when it is enlarged? The positive aspects of a disc with a universal central diameter include:

• Availability - these discs can be found everywhere. As a rule, they are produced for a large number of brands and models, so it will not be difficult for you to find the right one for you.
• Versatility - large center bore rims fit many models.
• Price - Since this product is made in large quantities, the price is slightly lower than for "exclusively" selected discs.

But not only pluses can be encountered if you choose a disc with an increased central diameter. This choice also has not very pleasant consequences:

• At high speeds, due to the loose fit of the disc to the hub, the car starts to “beat”. Only disk replacement can save you from this unpleasant phenomenon.
• In the worst case, if you choose the wrong wheel and do not put spacer rings, the threads on the nuts may break off the wheel. This is an extreme option, but it still happens if you neglect the safety rules.

Hub diameter for different vehicles

Each car has its own list of acceptable wheel diameters. The parameters may vary, usually you can find them on a sticker next to the driver's seat or from the technical specifications of the car. A variety of diameters of the central hole sometimes introduces buyers into bewilderment. They differ sometimes literally in 0, 1 mm. There are no uniform standards, so some manufacturers indicate the data more accurately, while others less. Some self-respecting disc manufacturers go further and indicate not 1/20 of a millimeter, but up to as much as 10 microns, i.e. up to 0.01 mm. What standards are adopted for the most popular car brands?

• The diameter of the central hole of the VAZ disk will be 58.6 mm.
• The same figure for Audi is 57.1 mm.
• The diameter of the central hole of the Honda disc is 64.1 mm.
• BMW's hub diameter ranges from 74,1 to 72.6mm.
• In Citroen cars, the figures also vary - you can find cars with a central hole diameter of 65.1 and 58.1 mm.
• Fords also have a wide range of sizes: 57, 1; 63.4 and 64.1mm.

Diameter of the central hole for "Niva"

Domestic Niva cars have rather wide hubs. The diameter of the central hole of the disk at the Niva is approximately 98.5 mm or 3 and 7/8 inches. What car rims can fit this car if you can't buy original ones?

• Niva Chevrolet;
• Volga (GAZ 31024, 29), different model years;
• Suzuki Escudo or Jimni.

Renault Logan center hole diameter

When choosing wheels, owners of Renault Logan cars often wonder what parameters to choose among the variety of assortment? For Renault Logan discs, the diameter of the central hole must be at least 60.1 mm. At the same time, it is better to select their radius with indicators R14 and higher. Many rims are suitable for such conditions, which greatly simplifies the task for drivers.

Expert Tips

When buying rims, experts advise to pay attention to the following details:

• If you buy a stamped disc, be very careful when choosing parameters. Even a deviation of 0.1 mm will be critical: steel rims do not use adapter rings, so you won’t be able to ride on such wheels.
• DiameterThe center bore on alloy rims can be easily identified using a special plastic ring. With it, you will know the exact parameters without resorting to outside help.
• If you purchase original discs for your car, then you will not need any adapter discs. As a rule, such a product is made exactly to the parameters of the hub hole of a car of a certain brand.

Reviews on rims with different center hole diameters

Despite all the subtleties, motorists should not worry too much if the diameter of the central hole of the purchased discs turned out to be larger than necessary. The behavior of the machine is influenced by completely different characteristics. Most motorists write that their driving on disks with a large hub hole diameter did not affect either the course of the car or the comfort of travel. The only problem you may encounter is difficult wheel mounting. If you accidentally bought discs with a smaller diameter, then the wheels will have to be “bolted”, and this is a laborious and long procedure. Therefore, before buying, be sure to ask the seller for which car models this product is suitable. This will save you a lot of problems. For the rest, you should rely on professionals - they know exactly how to properly install rims on your car.

Many drivers write that when installed incorrectly (for example, ifspacer rings forgot to put), the following unpleasant phenomena may occur:

• Steering wheel runout.
• Vibration when driving at high speed.
• Premature tire wear.

These side effects may occur because the wheel bore is not fixed firmly to the hub. Because of this, the car can start to "drive" from side to side. And shaking at speeds above 80 km / h is also not a pleasure to anyone. To understand what exactly the problems are, you need to check not only the coincidence of the diameter of the central hole, but also the balance of the wheels. Perhaps the problem lies precisely in them.

Results

Experienced motorists often say that it is never worth saving on two parts of a car - wheels and brakes. What is the diameter of the central hole of the rim you need to choose so that the car drives "like clockwork"? This parameter is not the main one when choosing a “new thing” for your car. But, of course, it should be taken into account when buying, do not take a size smaller than the diameter of the hub. But if you take a disk with a hole slightly larger than necessary, then nothing terrible will happen. The main thing is to contact a trusted tire shop, where they will install new wheels with all the additions necessary for your safety.
