Example scenarios. As others have said, going to a smaller (and more appropriate sized) tire will make a noticeable difference in gearing, rolling friction, unsprung mass, mpg, braking and acceleration. All to your advantage. It is a no-brainer decision.

235 85 R16 (or 7.50 x 16) tires on flat ground you should be able to do 55mph.

Also, you are going to be at too high of an rpm in a diesel with tires much smaller than what I mentioned above. Plus, on a 109 they will look stupid. You should also check to be sure you do not have a "1 ton" 109 as those had steeper transfer case gears.

completely off topic but if you are going to keep calling it him you might as well give it a name!

Jack might become Jacqueline if you snip his big rollers.

OOOH, I have something to offer: I bought a set of 5 General Grabber AT2 in a 235/85 16 for a job I was doing, and meant to order a different size. They are brand new. It would have cost me $110 to ship them back to the supplier, on top of the original $110 to ship them in. If that is a size you want to consider, let me know and maybe make an offer?

My obvious choice would be the Tdi200 for power and economy. However, an often overlooked second option would be the 2,5 TD (J19), providing that you can find one in decent condition. For one the engine is less noisy than the Tdi200 and also it would be less critical that you upgrade your drivetrain and brakes.
