The OEM tires (BF Goodrich Rugged Trail T/A) on my 2004 Tacoma DC 4x4 are coming to the end of their useful life.

The truck is primarily used on road as a weekend toy hauler (dirt bikes, mountain bikes, etc).

IÆm staying with OEM size (265/70R16).

IÆve narrowed my choices down to these:
Bridgestone Dueler AT Revo.
Michelin LTX MS.
Firestone Destination A/T.

One thing I noticed while researching was the great variations in tire weight. According to Tire Rack, the Firestone Destination A/TÆs are 51 lbs a piece, while the
OEM BF GoodRich All Terrain T/AÆs are 37 lbs a piece. Wow. Big difference.

Any info out there as to how tire weight affects a 2004 Tacoma DC 4X4 w/ v6?

Specially, impact on acceleration, braking, and MPG.

Thanks
Bob
