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.

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.

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)

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.
