I tried to find detailed specifications about wheels for a Grand Caravan R/T 2012 but i didnt found what i was looking for.

I need the bolt pattern and the exact offset, for the rest i know it's 17" by 6.5" wide. For the bolt pattern i think it's 5x5.0 (5x127mm)

Thanks

5-127 bolt pattern, I don't know the exact offset.

Here is what i found for the 2011 and 2012 R/T model

17" wheel
6.5" wide
+40mm offset
5x127mm (5x5") bolt pattern
71.5mm (2.815") center bore
12x1.5mm stud with 19mm nut

I've been trying to locate some wheels for my winter tires for my 2012 Grand Caravan R/T, and I have found none that fit. The problem appears to be that the R/T uses a different from brake caliper than any of the other models (though the rotor diameter is the same).

Has anyone found an aftermarket wheel that fits?

I had to get cheap 17" alloy wheels to put winter tire on my R/T 2012. Tried two different 17" steel wheels, none cleared the front caliper. Didnt tried 18" steel, they will probably be ok. But you will have to find an equivalent 18" tire to replace the 17" size, on my side the winter tire i wanted was not available in 18" equivalent so i bought 17" alloy wheels and the van look nice.

Don't know where you are located, but I was able to get some alloy wheels that are similar to the originals from RTX Wheels, which I believe is a Canadian firm.

What is this "winter" thing of which you make reference?
