Looking to re-shoe the wife's truck before winter and shopping around currently. My default is the Michelin Defender LTX M/S but I'm real tempted by LTX A/T2 as well as Goodyear's All Terrain Adventure with Kevlar. I'm sure in practice any of these three would be an excellent tire but I'd like to balance the best MPG along with the best snow & wet traction (I know, kind of opposite priorities). Does anybody think the Defender LTX M/S would provide any measurable benefit to MPGs or should I just go with the GY which is 3PMS (but only 640AB as opposed to 800AA)?
