I have a retired 2000 GMC Savanna 250 with 225/75R16 tires that have plenty of tread, no signs of dry rot, and are only 3 years old.

My newer vehicle is a 2009 Ford E350 extended, and it needs at least two new tires, these tires are older and have more wear. It is labeled for 245/75R16.

Can I put the 225 tires onto the E350 rims, would it change the safety/traction/reliability of the vehicle, and if so, how much?

It looks like the bolt patterns are the same, would using the rims and tires from the GMC change the answer?

As was pointed out, the outer diameter isn't quite the same, but it's not a major problem. The sole distinction I would be worried about would be load range. For example, an E350 van most likely wants to have a LT, E load rated set of tires installed. However, if the tires on your Savanna are P rated (i.e. not Light Truck), I would not install those on your Ford.

Diameter is 4% smaller Width is about 9% smaller

Since you are going to a smaller tire...
The speedometer will read higher than your actual speed by about 4%
You will not need to worry about rubbing.
Traction may be less, but should be sufficient.

I am not familiar with tire pressure monitoring systems, so I cannot comment on that.

I would say go for it.
