Hi all, new member here...

I have two Grand Caravans, a 1990 LE, and a 1996 SE (recently acquired). Love them for long road trips. I will have a few questions over the next few months related to these two cars, starting with this one about wheels.

The wheels on the 1990 car are much nicer than the base level wheels on the 1996, and the newer car is my daily driver, so I'd like to just swap wheels between the two cars. BUT...are these wheels perfectly interchangeable? They are both 15 inch, but what about the width, and the "offset" (if that's the right term-if it's not, what is the right word)? I've not yet tried them for fit, but I'm guessing the hole pattern would be the same. It does seem like the 1996 has a bit more clearance up front around the struts...that will be a bonus if I ever need to chain up in snow.

Please correct me if I'm wrong, but I'm assuming the wheels on the 1990 are factory optional since this is the top of the line LE (w/leather seats and factory sunroof). They are painted silver, the caps don't cover the entire wheel, and are the kind that bolt on from the back and remain attached when the wheel is dismounted.

Wheels on the 1996 car are almost certainly the base steel wheels, black or very dark, with big ugly wheel covers made of plastic.

Does anyone know if I can I safely swap the wheels? Are they exactly the same, or do they have a slight difference that won't matter? Or is there an offset issue that might be a problem?

Thanks!

Measure across the studs for an approximate bolt circle diameter. I seem to think that the NS minivan had a larger circle than the AS.
A Hollander interchange manual may give you what wheels can directly interchange safely.

The bolt circle is the same on the 1990 and 11196 if both are 15". I had the same wheels you have on your 1990 on my 1991 van and used one as a spare on my 1999 until I got new tires.
I would double check though that everything clears. Widths and offsets may be different even though the bolt circle is the same.

Since posting my question, I did try exchanging one wheel and it did fit the bolt pattern and the hub. Careful measurements with instruments designed for building houses, I did manage to find out that the offset is very close between them, though not exact...within 1/8 inch, and I believe the width is the same, so it's at least very close. But I like the idea of using Tirerack.com to see if numbers match up there. Also I've been intending to see if the interchange manual was available on line. I appreciate the responses!

The early 90s tires run so close to the front suspension strut that you have to use low profile chains if you want snow chains.

I don't know about 1996 and such, but do note tire size seems to have gone up. (1994 for example was already up from original, 1996 has substantial differences in general from 1990-1995.)
