The inches used to describe tire size refer to the diameter of the tire’s rims, and the recommended size of tires should always be used. Discover how tire sizes work and how wrong sizes can be detrimental with tips from a mechanic in this free car-care and automotive maintenance video.
Simple and easy to understand!
See my drawing at youtube “Projeto tire size”. Projeto means ‘project’ in portugues.
215/65-16 …… 65 is a percentage of the width which is, in this case, 215 (mm). So, a 205/65-16 is at the same time less wide and a little lower because 65% of 205 gives you a smaller number for tire wall height. See my drawing no “Projeto tire size”.
Thanks for the videos Richard
I’m a newbie and your videos are really helping towards my goal of being a hobbyist auto tech.
I just bought some tires today and wondered what the numbers meant.
very helpful
Donk ride owners worst nightmare.
I would love to see him try to explain rim offset.
That would be funny.
Overall hes right, but forgot some things like.
Treadwear number, What The letters such as R,Z,Y mean, And how to tell the born on date of the tire.
very good to know!!! thx
thnx
Hahah this guy is hilarious… just like an Auto Technician. (Auto Technicians don’t really care about tires, so they don’t really know tires; they just know what makes them wear improperly)
i totally understand o_0
Trick or Treat
3 makes sense. thanks a lot, appreciate the info
jayc2586:
In the example shown in the video:
1) The ’215′ means that the tread is 215 millimeters across.
2) The ’65′ means that the height of the sidewall is 65% as wide as the tread. For the tire in the video, the sidewall is 139.75 millimeters high (215 x .65 = 139.75).
3) The spokesman in the video didn’t mention it, but if you change tire sizes, and thus change your overall tire/wheel diameter, your speedometer will be rendered inaccurate.
THANK YOU… I finally know what those numbers mean!
