My 1984 D50 4X4 Turbo Diesel Build/Modify/Correct

[xboxrox]

Thanks guys for the tire size info; there is no tire size label on driver's door sill, only wheel size (15-6JJ) GVWR VIN... Unfortunately, I did not keep all the original papers & maintenance records for this truck... Opps..? I have the original 1986 owners manual in glove box, will look... It had some sort of RV or trailer looking type tires when we got it from the govt auction...

1986 Owners Manual ~ G78/15 for the 4x4 truck (on page 91)

For future tires:
1) try to find tires that most resemble original equipment

Desired tire qualities:
1) low rolling resistant
2) low noise

My truck is getting 14MPG city ~ carb cleaner squirted into carb & new ignition coil ~ nothing else checked yet~ still lacks power & misses...
