Oz Prius Tyres

Hi folks,
Today I had a closer look at the info on the tyres of my Oz Prius.
This is what I found:

Michelin Energy tyre
195/60 R15 88V-XVI
Green X
Treadwear: 240
Traction: A
Temperature: A
Max. Pressure: 51 PSI
Tread Plies: 1 Polyester + 2 Steel + 1 Polymide
Sidewall Ply: 1 Polyester

Not knowing what a lot of this info meant, I searched and found the following relevant sites :

http://www.tyresave.co.uk/tyreinfo.html
http://www.tyresave.co.uk/tyrspeed.html
http://www.indiacar.com/infobank/tyre_markings.htm

and the following quote on a Michelin site:

"XSE Technology Green Xâ„¢
Pioneered by Michelin, this breakthrough ‘green’ technology is still the standard to beat.
A special compound that reduces rolling resistance, Green X increases fuel efficiency
and decreases pollution, without sacrificing any performance, life or comfort. "

I hope that is of some interest.

Regards,
kenmac
