I want to put a set of Rally wheels on my 56.
I have a disc brake front end and drum rears.
I’d like the same size front and rear.
I presently have 225r7015 tires now, want to replace the tires too. Redlines are my choice. Size suggestion?
So what’s the wheel width an offset.
15x6 or 15x7
Offset?
I want everything to fit without interference.
Thanks.

Stock style rally's come in 6, 7 or 8" widths and usually have zero offset. Back space on factory rims usually puts the wheel mounting face in the center of the wheel.
You have to decide what size wheels you want. Any of them will fit in the rear with a 6 or 7 in the front.
Tire size is also up to you. Do you want bigger or smaller then your current setup? 235-60's would fit fine all around on 7" rims.

Specs

I have a set of 225r70/15 Goodrich redlines coming
Want to mount them on a set of 15x7 rally wheels
Have a disc brake front end and was wondering about backspace and offset
4.25 inch offset and a 6 offset sound right?
Thanks

My 57 has 15x6 Ralleys and old 215/70-15 Firestones up front. On the rear are 15x8 Ralleys w/235/60-15 BFGs. Everything fits perfectly, with room to spare. Coincidently, all 4 tires have the same diameter as 6.70x15 original tires on 55-56 tri-fives. When I drop the front 2", I'll find out how much clearance I'll end up with.
