What is the difference between passenger (P) and light truck (LT) tires. I have been told the main difference is the number of sidewall plys. But why just the sidewalls? Also, given similar tread patterns, would there be much of a difference in ride/cabin noise putting LT tires on a minivan? Thanks!

Someone else can give you a technical definition, but basically an LT tire is a heavy duty tire. It's stiffer and is built to handle heavier loads for pick-up truck and towing applications. It won't hurt your minivan to run LT's, but the ride quality and gas mileage will not be as good as a P range tire. Some tires are offered in a C load range too, which I think is a compromise betwen the two.

Jay is pretty close but you have to consider the load you are carrying. If you frequently fill your van and hit the highway, you may be running your "P" tires at full carrying capacity. "LT" tires comes in C (6ply), D (8ply) and E (10ply). Asess your loads, pick a tire (load ranges are different for all manufacturers regardless of letter code), probably P or C. Whatever you do don't use any size that is not specifically recommended by the manufacturer of your van.

I say get the LT's. A tougher tire is safer when you encounter road hazards or carry loads or a bunch of passengers.

As to ride, if that concerns you get an LT that's oriented toward pavement use and comfort.

When I took the P's off my 4600 lb. van and put on "C" range LT's like that, Bridgestone Dueler H/T's, the ride was microscopically rougher on little bumps, but much much better on washboard stuff. The heavier tires soak it up.

If I had got, say, the never-maligned by any poster I've ever seen, BF Goodrich AT, then I suspect they'd feel a bit more trucky.
