Rims

Important measuring size of a rim is depth of a press fitting of "d". It designates distance between the middle of a rim and an adjacent surface on a wheel nave.


So the steel rim for Audi A4 looks. You will find the following data which have been beaten out in metal

1–rim designation;
2–depth of a press fitting;

3–detail number.


The real wheel bolts for rims from steel and light metals from Audi learn on notches on a head of bolts.

On Audi A4 it is possible to put rims with the following designations: 6 J X 15 ET 45 or 7 J X 15 ET 45. Sometimes on a rim the additional designation «Н2» still meets. Figures and letters mean the following:

6 or 7: the width of a rim in inches, is measured on a basis onboard закраины rims across the direction of movement of a wheel.
J: designation of height onboard закраины rims.
Х: depth of dredging of a rim.
15: diameter of a rim in inches, is measured from a board to a tire board.
ET 45: depth of a press fitting of 45 mm.
Н2: rim designation with double the hampy. Two cambers inside, in a rim bed, do not allow boards of the tire to slide off with its onboard закраины at lateral loading (sharp turn at low pressure of air).

Wheel bolts and rims is a system

Wheel bolts and rims represent constructive unity and consequently they cannot be divided. The conic nest in fixing openings of rims precisely corresponds to a cone of a wheel bolt. Other forms of a cone cannot guarantee reliable landing of a bolt and, therefore, wheel fastening. For rims (steel and light metal), established on Audi A4 at plant, approach exclusively so-called bolts with koronchaty heads (details No. 431 601 139 And). They are recognized on notches above on a bolt head.

Rims for winter tires

Winter tires should be bought at once with the corresponding steel rims. At first sight it is more expensive, but, on the other hand, relieves of regular shift and balancing of wheels. Tire shops often offer sets at the similar price. For winter tires they offer standard rims of 6 J x 15. Or second-hand rims are bought.

Rims from light metals under the influence of salts can корродировать to a condition, unsafe for traffic. Therefore it is necessary to eliminate damages of a covering rim of a varnish as soon as possible.
