The size distribution on the RAV 4 is taken into account when selecting new wheels. The safety of the vehicle's operation depends on the conformity of the spare parts with the manufacturer's requirements. At the same time it is necessary to remember about other parameters of discs. Installation of non-standard spare parts or components from other cars increases the load on the hub bearings, and tires may scuff the elements of the body structure and suspension arms when turning or driving on an uneven road.

The concept of axle size.
The term describes the diameter of the circumference on which the holes for the bolts or studs, required to secure the wheel to the hub. The manufacturer has set tolerances for the dimensions of the channels in it, which are compensated for by a tapered surface on the fixing elements.
If the parameter is violated, the wheel cannot be mounted on the vehicle. Because of the change of alignment, a wheel wobble in motion, causing vibrations and destroying hub bearings and suspension components, and worsening the handling of the crossover.
Features of parameters
In addition to the axle size (designated in catalogs as PCD, or Pitch Circle Diameter) when selecting components for the assembly of the wheel, it is necessary to consider
The outer diameter of the rim, which determines the size of the tire;
rim width;
Pitch (the gap between the vertical plane of symmetry of the wheel and the line of external surface of the hub edge);
DIA bore diameter, which determines how the disc is centered when it is mounted on the hub.
There may be additional information in the wheel marking. For example, some manufacturers code the design of side edges or indicate the presence of ring hump on the rim with letters of the Latin alphabet. Parameters do not influence characteristics and are not taken into account when selecting a wheel.
The importance of the correspondence of tire size parameters for the car Toyota RAV4
When the factory requirements are violated, the wheel run-out occurs, which leads to the vibration of the car while driving, worsens the steering and quickly brings out the suspension parts. The tire experiences excessive loads and the tread wears out several times faster than under standard operating conditions. When using spare parts with an increased DIA value, it is acceptable to use adapters made of plastic or aluminum, which compensate the size difference and do not allow for misalignment.
Rims and tires mounted on different bodies and configurations
Beginning with the XA10 generation, introduced in 1994, crossovers used steel or alloy wheels of at least 16″ in diameter. The manufacturer supplied cars with different brands of tires designed for use on paved roads. There is a label on the center pillar of the car body, which shows the permissible wheel sizes and tire pressure values depending on the load.
The information is also listed in the factory instruction manual, attached to each crossover.
First Generation
The XA10s offered from 1994 through 2000 used five M12x1.5mm threaded studs, evenly spaced on a 114.3mm diameter circle. The spindle's calibre is ET45, the rim size is 6.5Jx16 (parts with 7.0Jx16 are acceptable), and the diameter of the guide hole is 60.1mm. Dimensions are independent of body type and engine power. The manufacturer prescribed the use of tires size 215/70 R16 with an operating pressure of 1.8 atm, the use of other tires was not recommended.
Second generation
The XA20 used steel wheels with plastic hubcaps, or aluminum alloy wheels (though the design was different from that on the XA10). The wheels used were 6.5Jx16 and 7.0Jx16 with an ET45 hub. The allowable tire size was increased to 235/60 R16 (pressure from 1.8 to 2 atm). The increase in width had a positive effect on stability and trajectory stability when driving on country highways. The PCD value and the way of fixing the wheels to the hubs have not changed compared to the first generation of crossover.
Third generation
In 2005, the production of the XA30 generation began. The basic machines were with steel rims 16″ in diameter, equipped with decorative hubcaps with the manufacturer's logo. Rim width was 6.5Jx16 at an ET45 offset. The manufacturer used 215/70 R16 tires with an air pressure up to 2.2 atm.
Some versions had aluminum alloy wheels. Some versions had 6.5Jx17 and 7.0Jx17 rim widths, designed for 225/65 R17 tires (working pressure of 2.2 atm). Wheel and tire size has not changed since the restyling in 2008 and 2010.
PCD and offset are the same (5x114.3 mm and ET45, respectively).
Fourth generation
Generation XA40 appeared in 2012, equipped with steel or alloy wheels with 7.0Jx17 rim width. Tires size was 225/65 R17, which provided a good level of comfort and dynamics. Also there are cars equipped with wheels with a rim width of 7.5Jx18 and the distance of ET39, designed for 235/55 R18 tires.
After the 2015 RAV4 redesign, the rims and hubcaps were redesigned, but the geometric dimensions remained the same. The wheels were mounted on 5 studs, located on a circumference of 114.3 mm in diameter. The manufacturer allows the use of tires 225/60 R18. Installation of tires with a tread width of more than 235 mm is not possible without upgrading the chassis.
Fifth generation
The basic equipment of the crossover generation XA50, introduced in 2018, includes aluminum wheels 7Jx17 with an ET39 offset and tires size 225/65 R17. On the improved versions there are wheels with modified design and tires 225/60 R18 or 235/55 R19 (rim width - 7.0Jx18 and 7.5Jx19, respectively, the departure - ET40). By reducing the profile height, the wheel diameter is preserved, providing stable ground clearance.
For the U.S. market, a version with 8Jx20 wheels ET40 and 245/45 R20 tires is available. All wheels have a 5x114.3 mm bore.
