Question

FIRST CORRECT ANSWER GETS BRAINLIEST AND 50 POINTS!!

Answer 1

Answer:

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!
