It can be seen from the measurements that the difference between 235 and 245 tires size is minimal. They can work as a interchangeable for each other as rims size also may not vary too much.

However, this replacement should be done after discussing the authorized company’s policy about tires and their replacement. 

Moreover, experts and certified mechanics should be consulted before interchanging both tires. The 245 tires should be preferred over the 235 tires at the time of replacement as it is a bit bigger and means 245 can perform better than 235 tires.

are 235 and 245 tires interchangeable? Although 245 is mostly preferred over 235, at times, 235 can also replace 245, fulfilling the tire’s required purpose with smaller dimensions.

All interchanging , either 245 over 235 or 235 over 245, should be done under the supervision of certified and expert mechanics to avoid any unauthorized and unexpected incidents.

The tire size accounts for too much of the vehicle’s performance, running speed, and frequent maintenance, regardless of the vehicle, truck, car, tractor, or any other vehicle.

It is always preferable to use bigger tires than smaller tires when options are available in the market. Bigger tires are always preferable over smaller tires when it comes to the size of the tire.

However, the difference between 235 and 245 tires is not so high and is also acceptable for replacement.

235 Tires Size 

For instance, let’s take the example of P235/70R16 (code discussed below in more detail) to understand tire size better.

235 tire

The 235 tire is smaller than the 245 tires, with a height of 27 inches and a width of 9.3 inches. So P235/70R16 here can be read as a tire with the passenger car tire 235, a 70% width tire when measured from surface to the rim, and a tire with a diameter of 16 inches.

This is the exact way to read the tire size, and it should be done in comparison when choosing from different tires.

245 Tires Size

For example, let’s take 245/75R16 for a more precise and better understanding of the 245 tire size reading. The 245 tire is ⅜ bigger than the 235 tires, with a height of 27.65 and a width of 9.6 inches, sometimes making 245 more preferable over 235.

However, the difference between 235 and 245 tires is minimal even when compared. So 75 represents the aspect ratio of tire 245, and R refers to the radial ply construction with a wheel diameter of 16 inches.

However, this does not eventually affect the performance of the vehicle a lot as it is not a big difference, over which 235 tires should be rejected or be said lesser in any way than 245.

What Is The Actual Purpose Of The Numbers Mentioned On Tires?

Numbers mentioned in the tires have some purpose and meaning as well. There are many subcodes for tires 235 and 245. However, for ease, let’s take one specific code to make understanding the number reading easy. 

P235/70R16 Code

Let’s start with the first letter, P, which refers to Passenger Car Time. However, in some other tires, there could be codes T, LT, and ST, referring to Temporary Spare, Light Truck, and Trailer, respectively. 

Letter R, which comes after the 70, is a variable that measures the aspect ratio of the tire. The aspect ratio can be measured from the wheel’s rims moving around the wheel’s surface area till the external tread.

R is called radial ply construction, while some other tires may have written D instead of R meaning Diagonal.

Simultaneously, 16 is the diameter size in inches, and it measures the diameter of the wheel. Here 70R represents that according to the aspect ratio, the cross-section width of the tire’s sidewall height is 70%.

245/75R16 Code

According to the research, a standard size limit has been recorded for the width of the tires between 125 to 335 mm.

However, here 245 represents the width of the 245 tires to be 245 mm. 75 refers to the tire aspect ratio that can be measured from the width area to the height of the area. Although the lower this aspect ratio would be, the greater control the vehicle will have while driving. 

Moreover, here also 16 refers to the 16 inches diameter of the tire, while there are 10 and 23 inches diameter tires available in the market.
