Aesthetics matter, and it shows! Very often motorists who want to replace their alloy wheels opt for this choice because they want to change the look of their car with the aim of giving it a more fascinating appearance and to make their wheels stand out more. The most expressed desire by customers is to increase the size of the tires and consequently of the wheels, even if not listed in the booklet, enhancing the aesthetic appearance of the machine.
But, if by law I can only fit tire sizes transcribed in the vehicle registration document, how is it possible to do all this?
This is the so-called INCH-UP, a practice that consists in having new tire sizes added to the vehicle registration document, also by increasing the diameter and consequently also that of the wheels, subject to the authorization of the competent motorization that will need some documents that we will see. in detail shortly and which will be provided during the purchase and assembly phase:
Now let's see together the necessary steps to be able to make the inch-up:
First of all you have to look for the right circle that suits you. In this phase you must not only be guided by your personal taste but also by the compatibility of the rim with your car.
First of all, you can then search for the wheels compatible with your car from the CambioRuote home page, by entering a few simple data about your car that you will surely be aware of (or in any case easily available in the vehicle registration document):
When you have entered these data, all you have to do is select the diameter of the rim you would like to mount on your car from those indicated.
The wheels that will appear are all NAD approved and therefore perfect for proceeding with the inch-up.
Before proceeding with the purchase, ask the CambioRuote staff for the list of areas of use, a document containing all the possible installations for that particular rim and the tire sizes allowed with your car, in order to also know the tire sizes. tires that you can mount.
PURCHASE
Once you have purchased tires and alloy wheels, you will find the certificate of conformity in the boxes of the latter, a document certifying the homologation of the wheels with an approval number that will also be included on the wheels themselves.
PAYMENT OF POSTAL BILLS AND APPOINTMENT IN MOTORIZATION
When you have completed this step, you will have to pay two postal bills worth 16 and 25 euros and make an appointment at the motorization to test the car and be able to add the new measurements to the booklet. The engine must be in the same province as the tire dealer where you will fit the new alloy wheels.
ASSEMBLY OF NEW ALLOY WHEELS
Given the long engine times, you will be able to fit the new wheels only a few days before the appointment. When the wheels and tires are fitted, the tire dealer will provide you with the correct fitting certificate that you will need to bring along with the rest of the documentation on the day of the appointment.
That's all! Now you know everything it takes to be able to inch-up. But what if you wanted to inch-down and install sizes with a smaller diameter? No problem, same procedure.
