Tire size comparison 275/70 R18 and 255/70 R18.

In the table above you can see a detailed comparison of the difference in dimensions, parameters and performance between a 275/70 R18 tire and a 255/70 R18 tire. The results of the calculations are also presented in the form of visual models (infographics), on which the tire with a size of 275/70 R18 is on top, and with a size of 255/70 R18, respectively, at the bottom. The visualization was generated in two projections: lateral (left) and frontal (right). The online calculator compares tires according to the following characteristics: diameter, width, circumference, profile height, revolutions per km, ground clearance change. Additionally, a potential deviation between the actual speed and the speed displayed on the speedometer is calculated, which can occur if the difference between tires 275/70 R18 and 255/70 R18 is significant.

Tire size change table

Every motorist eventually comes to the moment when he wants to make a certain upgrade of the car. But any modification entails not only design changes, but also the improvement or deterioration of running gear. But is it possible to change tire sizes? Undoubtedly, this also applies to car tires with disks. Replacing tires and wheels is one of the most popular tuning manipulations. Everyone knows that wider and higher tires give the car solidity and attractiveness, even if the modified vehicle belongs to the budget category. But is increasing tire size really a good idea? Let's look at three options for replacing rubber with a factory dimension of full profile, low profile or extra low profile tire replacement options.

To begin with, it should be understood that the native size is chosen by designers for a reason. It is formed based on the technical capabilities of the car, its traction and acceleration characteristics. Also, the initial size is affected by the shape of the car body, weight, and its purpose.

Tire size is determined by three values, for example, in a tire with a size of 185 65 R14 they will be interpreted as follows:

  • 185 - profile width (not the tread!) in mm;
  • 65 - profile height in % of the profile width;
  • R14 - internal diameter in inches.

Changes to certain parameters have consequences in terms of clutch quality. Moreover, each case is private, there is no specific rule on how this or that modernization will affect the ride. In case of a planned change, it is necessary to consult with a specialist. Below is a table of replacement tire sizes.
