FIRST CORRECT ANSWER GETS BRAINLIEST AND 50 POINTS!!
The dimensions of the tire are 190/75-15.

1. Find the width of the tire.

2. Find the length of the side wall in milimeters and inches.

3. Find the diameter of the whole tire in inches and milimeters.

The dimensions of the tire are 190/75-15.

The first number is the width of tire in mm, here is 190 mm

The second number is ratio between sidewall and width of tire in %, here is 75%

The third number is diameter of wheel in inch, here is 15 inch or 15 x 25.4 = 381 mm

Then, we have:

1.  The width of the tire is the first number: 190 (mm)

2. The length of the side wall = width x ratio = 190 x 75/100 = 142.5 mm

or 142.5 /25.4 = 5.61 inch

3. The diameter of the whole tire:

D = diameter of wheel + sidewall x 2

   = 381 + 142.5 x 2

   = 666 mm or 666/25.4 = 26.22 inch

Hope this helps!
