ADC for 15 volts sginal from Gyro

Hi every one. I want to use the ADC of the arduino for converting analogue signals from gyro.The analogue voltage output from gyro is as maximum as 15 volts and as low as -15 volts. Now that the arduino understands voltages from 0 to 5 volts, can I use the arduino for this purpose? If yes, how to transfrom the signals? Thanking in anticipation.

Perhaps something like this could work...

EDIT: On second thought - it's not quite balanced: +15 --> 5V @ A0 +2.5V --> 2.5V @ A0 -10V --> 0V @ A0

The upper 10K would have to be lowered to somewhere around 6.8K.
