    I can't put it off any longer so I'll be getting four new tires next Monday. I've got it down to a choice of two (both available and similar in price).

    1. Bridgestone Ecopia EP100: Bridgestone ECOPIA EP100 Tyre

    2. Michelin Energy XM2: MICHELIN Energy XM2 - PassengerCar - www.michelin.com.au

    No snow or ice here so that's not really a consideration. I want good fuel economy and good tread life. At the moment I'm leaning towards the Michelins, but my nagging doubt is that I don't have any actual rolling resistance data on that particular model (even though I know the "Energy AS" is really good). The "Energy AS" is not listed on the Australian website and the XM2 seems to be their current best in terms of LRR.

    Can anyone help me decide? :D

    At the moment the big thing in favor of the Ecopias is that they're a know quantity in terms of LRR and fuel economy (eg user feedback from this site along with tire-rack tests).

    I'd like to try the Energy XM2 but unfortunately they are a bit of an unknown. I'd like to think that they are equal (or better) than the "Energy A/S" (which actually beat the EP100s for LRR in the tire-rack tests) but that might just be wishful thinking.

    I wouldn't get the EP100 because rumor has it that it may be discontinued soon. I would not be surprised since the EP422 features the second generation of Ecopia Technology and is an A/S tire, which makes more sense for most hybrid customers.

    MB860 ?
