Hi

I am in the process of buying a 1973 Cuda and need to buy some original style rims. The Rallye style
I do not know the sizes that would fit and would be grateful for some advice. I have been looking at this supplier unless someone knows a better place. https://www.cokertire.com/mopar-rallye-silver.html

I was planning on getting 15 inch rims and wider at the back. Do you guys know if 15 by 7 at the rear and 15 by 6 at the front would work or can I go wider at the back?

I have been told that the bolt pattern for a 1973 would be 5 by 4.5. Second question is what tyre would work. I have looked at BFGoodrich tires. I was considering 225 on the front and 245 on the back. Would this work on these rims or could I go wider at the back?

I would be grateful for any help you can offer.

Thanks
