Recommendations for choosing tires (Hyundai Sonata EF)

1. When choosing tires, pay attention to the marking. The geometric dimensions, load capacity and maximum speed must strictly comply with the manufacturer's recommendations. The landing diameter of the selected tire must correspond to the landing diameter of the disk.

2. There are several types of tires: road, universal (all-season), winter, and cross-country. The type of tire is selected based on the operating conditions.



3. When replacing tires, use only tires of the same size and design as the recommended tires for your vehicle and with the same or greater load capacity.

4. Using any other size or type of tire may seriously affect handling, comfort, speedometer/odometer accuracy, ground clearance, fuel economy, clearance between the vehicle body and the tire or snow chain.

Warning: Do not mix radial and bias tires. This may cause dangerous vehicle behavior, leading to loss of control.

5. The marking may contain one of the following designations:



205 - nominal profile width, expressed in millimeters. This size is specified by the manufacturer.



65 - the ratio of the height of the tire profile to its width, expressed as a percentage (%),



If this designation is absent, the ratio is 0.80...0.82.

This size must match the tire size recommended by the manufacturer.

R - designation of radial tire;

B - designation of a diagonal tire. Radial and diagonal tires differ in the arrangement of the cord threads. Radial tires have lower rolling resistance and a longer service life compared to diagonal tires.

15 - tire seat diameter, expressed in inches. This size should correspond to the tire size recommended by the manufacturer.

94 - conditional index of load capacity. It is selected based on the table "Indices of load capacity".

H is the tire speed index. It is selected based on the table "Tire speed indices".

6. When marking tires, optional designations may be used:

PR is the ply rating, a conventional value indicating the load-bearing capacity of the tire, that is, the strength of its carcass (4PR - tires for passenger cars, 6PR and 8PR - tires for light trucks and minibuses).



7. Designations used in marking tires of American manufacture:

LT - indicates the area of application, for SUVs, small trucks and minibuses; in this case, P is a passenger car tire.
