In the table above you can see a detailed comparison of the difference in dimensions, parameters and performance between a 305/65 R18 tire and a 305/80 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 305/65 R18 is on top, and with a size of 305/80 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. In addition, the potential deviation between the actual speed and the speed displayed on the speedometer is calculated, which can occur if the difference between tires 305/65 R18 and 305/80 R18 is significant.
If you want to compare other tyres, just select the required parameters in the drop-down fields and click on the green button.
The issue of selecting tires for rims has always been relevant for car enthusiasts, since every self-respecting driver needs to know certain parameters.
If the characteristics are not known and these parameters are not followed, the car will experience a significant deterioration in performance, which seriously threatens safety.
In order to select the rubber for the rims as accurately as possible, you should first study the marking of the rims:
Marking of the rim with dimensional indicators R13 4x98 ET35 J5 D58.6
It is the latter that plays the main role in matching tires and rims. In order to choose the right wheels for tires on passenger cars, you can use the table compiled by the specialists of Avtotire Kom. Or you can use the selection of wheels for the car by going to by reference .
