Fitment Guarantee
We continuously expand our offer and update the database so you can easily find the right wheels for your car model.

We select alloy wheels according to the manufacturer's catalog parameters. For some car models or wheels, it may be necessary to use spacers, and special bolts/nuts, which you can easily find in our store in the "Accessories" section.
The risk of error is minimal, but before installation, check whether the wheels fit your car, have no deviations, do not rub against suspension parts, and do not protrude beyond the fender. It is important to verify the goods BEFORE fitting the tires onto the wheels. Fitting tires is unnecessary and will prevent the correct diagnosis of the product. Alloy wheels should be fitted on both axles of the vehicle. However, if you visit a service/shop, inform the tire fitter to perform the above tasks first.

Tech specs:
The model:determines the appearance of the rim. By entering the model in the LadneFelgi.pl store search engine, you can search for rims in different colors and with other parameters.
Size: is the diameter of the rim in inches (1 inch = 2.54 cm). Possible sizes are predetermined by the car manufacturer. It is not allowed to use smaller rims than provided by the manufacturer.
Rim width: is measured between the rim flanges. The dimension is in inches. When choosing tires, take into account the width of the rim and the car manufacturer's recommendations.
Wheel PCD: determines the number and spacing of mounting holes. This is the diameter of the circle with the centers of these mounting holes. The diameter of the circle is given in millimeters.
ET, offset: is not a strictly defined parameter, such as spacing. It depends on the width of the rim. ET is given in mm. The smaller the offset, the more the rim is, which increases the wheelbase, positively influencing the car's stability. The service book or ASO provides only the parameters of the currently installed rims.
Center bore: it is the dimension of the rim center hole diameter given in mm. If the car has a smaller hub diameter, centering rings are used. The ring is used to center the rim in relation to the car's hub. After screwing it, no force acts on it. It is a safe solution used by all rim manufacturers.
Color: determines the colors in which the offered item was made. Pictures are taken under natural lighting.
TPMS Sensors - the parameter determines whether the TPMS pressure sensors can be used with a given rim.
