Tires are 195/70-14 BFG Traction T/A on bundts all three cars, although I run my pressure around 45 psi. Sorry guys, not trying to brag just was stunned when reading the original posts in this thread. I've always been under the impression my mileages with in the norm for these cars as I've always seen exceptional economy from diesels. I've even got a beater '98 Ford E-350 PowerStroke with 240K miles that was given to us and I've managed to get to 17MPG in mixed driving hoping to improve with more maintenance.
