Do you mean wheels? Tires are the rubber part while wheels are the metal.

Um... yes. I meant wheels I guess. The big silvery metal part, not the rubbery part. (Mechanical things are not my strong point.)

Where I live it is common on the Dodges for the standard wheels to be switched out with bigger ones to appeal more to the avareage buyer (again, in my area.)
Switching wheel sizes can reduce hauling. Depending on the size, up to 1/2 ton is lost, according to the Dodge site.
When I asked several different sales people why the wheels are switched like that when it reduces performance, I was told most folks prefer the way it looks with the special wheels/tires more than how it performs.

My friend's Dodge I mentioned previously sits higher than mine. Her wheels/tires are also measurably bigger than mine.
We both have hauled the exact same trailer before and it sits level on my truck and front high/tipped on her truck. We both have the same hitch bar on our trucks.

As an aside, I remembered after my first post that I received conflicting info on using the Ram 1500 Quad cab/Mega cab short bed to haul a GN. The regular sales people where like ... "Sure, no problem." (of course)
The truck/trailer/specialty shop place said not to do it.

The problem with new trucks and old GN trailers is there isn't enough clearance between the GN and the side rails and tailgate on the truck. When you properly adjust the height of the neck to where the floor of the trailer is level, you might have as little a 1-2 inches of clearance. When you go up a steep driveway or go around a corner, the trailer can actually hit the truck. Ever wonder why you see alot of trucks with a big dent right on the top of the tailgate?

Wrong. Let's have a lesson in tires:

There are two different measurement systems. One is metric and one is inches. Let's start with inches because it is more simple.

The form is as follows: tire height x tire width R wheel size.
For example many trucks will have a 31x12.5 R15 tire.

The metric form is more complicated. It begins with the width in millimeters, then the aspect ratio and finally the rim size. The aspect ratio is the complicated part. It is a percentage of the tire width that represents the height of the tire with the size of the wheel subtracted. For example a tall skinny tire with a small rim will have a very high aspect ratio. A short fat tire with a big wheel will have a very low aspect ratio. The form is as follows: tire width (mm)/aspect ratio R wheel size. For example, a common size is 235/75R16

The point is, the size of a wheel has nothing to do with the height and width of the tire. And no, I don't just mean "mud bogging" tires. For example many cars and trucks use a 15" wheel. But trucks generally have a larger tire with more sidewall on the very same sized wheel.

I understand that this is a horse forum that has nothing to do with anything automotive most of the time. But please, check your facts before spreading misinformation.

Check your facts and common usage, 31's are oversized mud bogging tires.

Look at any tire shop's tire listings, they are seperated by by the size of the hole, 14's, 15's 18's. The first thing you have to know is the size of the hole. Your 31's are meaningless info if you don't first know what size the hole is as you can get 31's in several different sizes.
I know exactly what the various numbers in tire sizing means you decided to be overly pedantic and try to point out errors in someones terminology, when every single person on this thread knew exactly what the poster meant by 20" tires.
SO get your facts straight before getting overly pedantic.

Bolded refers to the rim size / size of hole in tire.

Well, seeing as we are talking about a truck and a gn trailer here, we kinda already get that this is a truck tire... and since there are many "generalities" we can assume that a 15" tire on a truck is not going to be a low profile tire, as opposed to a 20" tire on a truck for 'dem 'dere city slickers that don't have to drive in mud and snow.

You also didn't mention anything about highway tractor tires which have another totally different measurement system. If you want that explanation, let me know and I'll get MDH to explain it to me again. I've forgotten over the years.

If you decided to go into all this detail because of the height relationship between the truck and the trailer, maybe you should have also asked about the suspension in both vehicles as well.

Two things have to be looked at for tires and rims. One is how much weight can a tire carry, that is stamped right on the side of your tire. Second is how much weight your rims are rated at, this can take a bit of research to find out. FYI, lots of larger rims are designed for looks and not carrying capacity so this is really important to find out.
