225/65/16 tyres...

vary greatly in price, i will be buying a couple of Avon tyres for £85 each including the lovely vat tomorrow after some loyalty discount. a quick search in google brings up an interesting fact!
225/65/16c equals the speed of light (225 / 65) / 16) * the speed of light = 64 858 945.2 m / s this was thrown out by google as i had not put in the correct tyre definition.
the tyre i was actually searching for should have been written like this 225/65 R 16 C which would have returned some more relevant results!
