On wheels and tires

Some questions about wheels and tires.

On Wheels
Example: 14 by 6
I understand that the diameter of the wheel is 14 inches. But is the "6" the width of the wheel, and is this measured in inches?

On Tires
Example: 195/60/14
I understand that the the tire is for a 14 inch wheel. I also understand that the width, and the tirewall of the tire is 195 and 60 respectively. But is the "195" and "60" measured in mm?

[khayib]

width is in mm and 60 is in % of the width.

Thanks!

Now I understand why fatter tires seem to have a thicker sidewall than thinner tires, even though they have the same "50 Series" profiles.

How about the wheels? When you say 14 x 6, is the 6 the width, measured in inches?

6 inches is the width. And then there's offset - JJ or E or something. Though di ko pa rin kabisado enough to explain it. I think may tech articles sa www.tirerack.com try mo na lang.

195/60/14

Yung 60 ay yun ratio ng kapal ng sidewall vs the thread width. Kaya you'll see "50 series" tires na iba ang height kung 235 ang width vs 275 ang with.

so 195/60 means that the sidewall is 60% of 195mm

The JJ, J or E letters on the mags are rim lip designations. Iba-iba po kasi ang design ng rim lips to be used on specific tires. Rims/Mags offset can only be distinguished from the box itself or catalogues form the manufacturer. It is rarely stamped on the wheel itself. But I have seen one set of mags with offset stamped inside.
