Look at the sidewall of the tire. You may see letters and numbers such as P245/45ZR17, P265/75R16, etc. They suggest the particular tire size and type, as well as the tire’s performance. The three digits indicate the width of the tire from sidewall to sidewall. Therefore, as long as the tire is 245 or 265, the distance in millimeters is the same.
The point is that width is the only thing that distinguishes the “245 vs 265 tires” discussion. Is there more to it? Yes, that 20 mm of width makes a significant difference in overall tire size, which defines vehicle handling, speed, and fuel economy. This is just a synopsis.
|245 mm Tire||265 mm Tire|
|Better traction in winter and snowy conditions||Better traction on dry and wet roads|
|Greater driving comfort||Better grip at corners and turns|
|Lower noise level||Less noticeable impacts from small obstacles|
|Lower rolling resistance for fuel efficiency||Shorter stopping distance for enhanced safety|
|More affordable||Better aesthetics|
The preceding comparison would not seem to be appropriate for everyone. This article has explained all of these conclusions so that you can choose what steps to take.
How Do 245 and 265 Impact the Other Specs of the Tire?
The following table describes how width relates to other resizing variables. We compare it to 245/75R16 and 265/75R16 tires. Both shapes are acceptable for passenger cars and light trucks.
|Sidewall Height||183.75||198.75||15 (8.2%)|
Most drivers do not worry about these estimates. On the other hand, the rate per mile cannot be taken for granted. The tire spins a certain number of times for each mile it travels.
The assumed tire size results in a number of revolutions per mile of 411.31 for 245 tires and 395.96 for 265 tires. Let’s gain some valuable insights through a simple analogy.
Factors to Consider
Both tires must be used, so both have their own set of restrictions. You would understand which considerations are influenced by tire width.
Driving Conditions and Traction
Traction is provided by both tire sizes, although in different ways. The contact pressure per square inch is higher than that of the 265 tires. The 245 tires make it possible to go through puddles by dispersing fluids. These narrower variants do better on ski slopes because they give more traction by digging deeper into loose snow and mud with more pressure.
Because the grooves trap and subtract fog from the surface, the 265 tire has a wider contact patch and more sipes (grooves) than the 245, making it more reliable on wet roads. A larger contact patch provides better grip and therefore better traction on dry roads or asphalt pavements.
In other words, unless you opt for the vehicle’s suspension, the larger of the two types may not offer better traction. If one chooses to purchase larger tires, the suspension can be adapted. Otherwise, the tires would make the car more difficult to handle, creating more harm than good.
Comfort and Braking Distance
Driving comfort is essentially determined by the amount of air in the tires. The 265 tires require a larger rim diameter than the 245 tires (as shown in the table). The air volume is minimal in this case. There is more air space in the high profile 245 tires than in the low profile 265 tires. As a result, the shorter one is quieter than the wider one and has more ride comfort.
On the other hand, the wider tires have better traction than the shorter ones. This is certainly the positive side. In addition, small holes cannot affect you.
Braking distance is another parameter that distinguishes between the two tires. Even after applying the brakes, your truck would have to travel a certain distance to come to a complete stop. The distance traveled by the 265 tires is less than that of the 245.
This is a great advantage in terms of safety since a shorter braking distance decreases the possibility of frontal collisions or hitting obstacles.
Rolling Resistance and Fuel Consumption
The driver’s tires need the energy to maintain a constant speed on any optimal surface, and this energy must be delivered by the vehicle, which is known as rolling resistance. As a result, your vehicle would have to work hard to keep the tires rolling.
Changing tires from 245 to 265 can improve rolling resistance, which translates into higher fuel consumption. Likewise, larger gears cause more friction in the car and require more fuel. The price could increase. However, these two considerations are not sufficient to support such a conclusion.
Since the narrower high profile tire version is more prevalent and productive than low profile and larger tires, the price of 245 mm high profile tires is typically lower than 265 mm low profile tires.
If your factory width is 245 mm and you prefer to use 265 mm tires, you may notice a small difference in shock absorption due to narrower sidewalls. As a result, noise levels may be higher.
The above discussion may convince you to replace the original 245 mm tires with 265 mm tires. You may even have learned that larger tires are associated with car speed. This is, in fact, false.
While there is nothing wrong with installing 265 tires, the outside diameter should be the same or even larger. Check that the load and speed rating of the new tire is equal to or greater than the load and speed rating of the old tire. This way, you should take full advantage of all the benefits of the larger tires.
