You are going to have to cut a lot out of the front and rear wheel openings to fit 37s on a stock truck.  I cut quite a bit out of my front fenders to fit my 35x14.50 Boggers and I have a few inches of lift from my D60 axles.

Over 250,000 isn't necessarily on its last legs. I don't know how much cutting it would take, but it could easily have plenty of life left.

Honestly, I don't know if it's practical to cut that much out of a stock truck to get 37s to fit. This is how much I had to cut out of my '88 to get my 35s to fit with the D60s:



I believe a 37x12.50 would also fit in my wheelwell, at least I hope so since I am switching to surplus HMMWV tires soon. The rear wheelwells will need a bit of cutting to keep from cutting the tread on the 37s. I'm reasonably sure this will work on the street for a little while but I have a set of springs off my old '74 W200 to go on the truck to lift it a bit more to work off road. With a stock truck on 1/2 ton axles, even with this much cutting, I doubt 37s would fit. It may not look like a lot, but this is about as much as you can cut from the stock fenders without completely doing away with the inner fenders and having to deal with the tire hitting the cab at the firewall.




Another issue is the fact that a 37" tire sitting at stock height will probably not turn very well due to the diameter of the tire hitting the frame and will not turn to the right worth a damn since it will hit the pitman arm and draglink. Another problem is that the stock D44 front axle is going to eat front axle joints like candy if you work it.
