Wheel sizes and required tire pressure for Toyota Camry

Types of devices

Today, dial and electronic pressure gauges are most often used to carry out measurement work. Electronic products are considered the most accurate, having an error of 0.05 bar. The devices are compact and particularly easy to use. If you need to get a simpler option, pointer devices are suitable. Mechanical products show large errors, but for home use they are quite acceptable. Some modern types of models are equipped with built-in devices.

Influence of various factors

You can check the air density of your tires using a pressure gauge. It is recommended to carry out this procedure inside a garage or box with cold tires. The temperature difference inside the moving and stationary wheels is significant: the tire heats up while driving. At the same time, the air supplied inside it has the ability to expand when heated and reduce its volume during cooling.

Procedure for measuring tire air density

From a theoretical point of view, inflating wheels to normal pressure values ​​is not difficult. From a practical point of view, everything is not so simple: after inflating the tires outside in winter to the permissible value, you will notice that during the trip the pressure inside the tires will change. This problem can be solved if you inflate tires in winter inside a warm garage or box after two hours of vehicle inactivity.

Incorrect pressure: what awaits the driver?

If you measure your blood pressure incorrectly and keep it that way for any length of time, it can have a number of consequences. For example, violations may occur that negatively affect the quality of machine operation:

• deformation in the tire area;
• presence of unnecessary expenditure;
• wheel inversion;
• incorrect behavior when moving.

Thus, any fraud and violations in themselves are not safe.

Camry V30 tire and wheel sizes

Unlike subsequent generations, the Camry 30 was equipped with R15 wheels. They are perfect for car enthusiasts who love a soft, smooth ride and save money; such “rollers” are cheap and protect the suspension.

Wheel sizes for XV30:

The diameter of the central hole (DIA) is 60.1 mm, fastening to the hub is a nut, drilling is 5x114.3, permissible offset (ET) is from 45 to 50 mm.

The minimum tire size that will suit the “thirty” is 205/65 R15, the largest is 215/55 R17.

Purpose of tires by type of operation

• Road summer tires - for highways at above-zero air temperatures. It has a harder rubber composition with lower thermal conductivity.
• Winter tires are designed for driving on snowy and icy road surfaces in winter. They are softer and can change the degree of hardness depending on changing temperatures. Most winter tires have studs installed.

• All-season tires allow you to use your car at any time of the year. However, when choosing it, you should take into account that all characteristics will be averaged, and in Scandinavian countries its use in winter is strictly limited.
• Universal tires have a set of properties that allow them to be used simultaneously on road, unpaved and off-road surfaces.
• All-terrain tires are intended only for soft ground and off-road use. When driving on the highway, it wears out quickly, gives low stability at speed and increased noise effect.

In the Russian climate, when using a car year-round, two sets of tires are chosen: winter and summer.

It should be understood that a high indicator of certain performance properties is always achieved at the expense of reducing the indicators of others: for example, if a tire has a declared increased mileage, then stability and controllability will be reduced, or the permitted maximum load in the characteristics of the rubber will mean greater fuel consumption and noise.

Standard level

Often a cyclist does not know to what level he needs to inflate the tires of his bike. This usually happens when purchasing tires with “unclear” markings or without them. This situation occurs quite often when, in search of cheapness, a person buys bicycle tires from an unknown manufacturer, the cost of which can be an order of magnitude lower than that of branded bicycle tires - “Continental” (Germany), “Michelin” (France), “Vittoria” (Italy) ) or "TUFO" (Czech Republic). In this case, you should use one of the tables, many available on specialized Internet resources.

For example, the standard pressure range for a bike of the “All mountain” or “Cross-country” category can be found in the table.

For a road bike, this tire value is chosen slightly higher and can be found from the corresponding tables on the Internet, but in any case you should not exceed the upper limit in PSI.

Features of tire size markings

All markings of automobile rubber are standardized in accordance with European regulations - a tire from any manufacturer, its properties, purpose and characteristics can be “read” in the symbols on its sidewall and in catalogs.

Tire size is determined by the following symbols:

• The capital symbol (d) indicates the mounting diameter of the tire rim, expressed in inches;
• Capital (D) – indicator of the size of the outer diameter of the working tire;
• (s) – the size of the profile width (when selected, it must coincide with the size of the seating width of the rim of the working tire without load);
• (h) – percentage expression of the profile series: ratio of height to width;
• (H) – profile height indicator.

There are three types of tire tread patterns:

• A symmetrical non-directional pattern along the tread surface, running with a double seam in the center - the most common universal type;
• Directional - for improved drainage and reduced noise;
• Asymmetrical implements different tire properties in one, often used in all-season or all-terrain tires.

Full list of marking symbols:

1. Indicator of maximum load weight and pressure (USA standard).
2. Marker for the inside of the tire on rubber with an asymmetrical pattern. In other cases, they designate the outer side (“OUTSIDE”).
3. Numbers of indicator of breaker layers, material of cord threads and type of frame.
4. Manufacturer's trademark.
5. Profile width indicator.
6. Percentage series ratio of the height and width of the profile.
7. Size designation (radial type).
8. Tubeless tire.
9. Rim seat diameter.
10. Maximum load capacity (expressed in index).
11. Speed ​​indicator (expressed in an index).
12. An indicator of the direction in the direction of travel of a tire with a directional type of pattern.
13. Date of issue.
14. Compliance with international safety certificates.
15. Tire model.

Additional symbols on tires can indicate the characteristics of the cord (“steel”) - steel cord, versatility (“R+W”), a factory-recovered tire (“retread”) or the marking of a tubed or tubeless tire, respectively (“TT”; “ TL").

Pressure measurement: algorithm

It is necessary to take only “cold tires” for measurements. This only means that in the last three-hour period the car should travel no more than one and a half kilometers.

It is necessary to ensure that the valve cap is unscrewed and a pressure gauge is attached. Typically, a table with standard indicators is attached to the door element or to the cap on the gas tank. If such a table does not exist, it can easily be found on the Internet. But the data may have several differences.

Camry V50 wheels

XV50 factory casting parameters: Central hole diameter – DIA: 60.1 mm, fastening to the hub – nut, bolt pattern 5×114.3mm, M12 x 1.5 thread

• 16 – 6.5Jx16 ET45
• 17 – 7Jx17 ET45
• 18 – 7.5×18 ET45

Let us explain with help what these letters and numbers mean. The first number is indicated for better understanding. The first number after the dash (6.5, 7, 7.5) is the width, measured in inches; to convert to centimeters, multiply this number by 2.54.

J – informs the design properties of the wheel (type of disk flange), not important for buyers.

x - indicates that the disk is not separate.

16 – landing diameter, corresponds to the diameter of the tire.

ET45 – wheel offset, in the presented case is positive and equal to 45mm.

bolt pattern (5x114.3) is the number of wheel fasteners and the diameter in millimeters along which the holes for bolts or nuts ( PCD ) are made.

There are officially two casting options for Camry on our market: R16 and R17. R18 wheels were offered by the manufacturer in North America.

How to check the pressure gauge

Instructions

The pressure gauge should, as a rule, be installed in such a way that its readings are clearly visible to operating personnel. The nominal diameter of the housing of pressure gauges, which are installed at a height of up to two meters from the level of the observation platform, should be approximately 100 mm, no less. At a height of two to three meters - no less than 160 mm. In this case, it is prohibited to install the pressure gauge at a height of more than three meters from the level of the observation platform. A special three-way valve or a replacement device must be installed between the pressure gauge and the vessel, which will allow periodic checking of the pressure gauge using a control device.

If necessary, especially depending on the operating conditions, as well as the properties of the working environment, equip the pressure gauge with a siphon tube, an oil device, a buffer and other additional elements that can ensure reliable operation of the pressure gauge and protect it from direct exposure to the environment and temperature.

Pressure gauges and pipelines connecting them to the vessel must be well protected from freezing.

Next, connect the monometer itself. Tighten it on the tee, slightly short of the pressure gauge itself, to expel the air.

Pressure gauges cannot be approved for use in such cases when: there is no seal or stamp with a mark indicating that the necessary verification has been carried out, the period for this verification has expired, and also if the pressure gauge needle does not return to the zero scale value when it is turned off, and if the glass of the pressure gauge is broken or there are any -even minor damage that may affect the accuracy of the readings. If a malfunction is detected, the pressure gauge must be sent for repair. Before submitting for repair, clean the pressure gauge from dirt and rust.

Optimal indicator

According to expert data, the optimal pressure indicator is 2.1 Atm. As the owners of this car note, minor deviations of this parameter are acceptable - approximately 0.2 units. For example, when driving fast and quickly cornering, the optimal value will be 2.4 Atm. If the roads are bad, parameter 2.0 is just right.

It must be remembered that the pressure in the area of ​​the front wheels will be less than that in the rear wheelbase.

For a competent approach to tracking the dynamics of an indicator, it is necessary to carry out its measurements.

Wise choice of tires for Camry 40

Tires are one of the important elements of a car, on which road safety directly depends. The correct choice of tires ensures handling, directional stability, a comfortable ride and affects fuel consumption.

All tires have a certain specification - each type differs in its purpose, having its own characteristics of the tread pattern, design features and chemical composition of the rubber.

When choosing, take into account the properties of the tire for operating conditions: seasonality, dimensions and standard sizes in accordance with the vehicle parameters, load (maximum weight), speed and range of road quality. The basic rule of an experienced motorist when installing new tires: for each wheel - one size, one design, one model and manufacturer.
