I am replacing my old beat 14inch mopar rally wheels with new 15 inch reproductions.

This is for a 74 Roadrunner.

on the front will go 15x7s with 4.25 inch backspacing,
and depending on what rear tires i use will go with 215/70s or 225/70s.

I have found posts that show215/70 will fit just fine in front. Do the 225/70/15s fit fine in front to? I thought I read a post where they did but cannot fint it.

On the rear, if I go with 15x7 all the way around, I will used 255/60s. (and the 215s up front)

If 275s fit fine on a stock 74 RR, I will go with 15x8s.

I have found posts that say the 275s are fine, and post that says it is too big.

Anyone here running 275/60/15s on their 74 RR and how do they fit?

Also, what size backspacing did you go with if they do.

Thank you.
 
The available Bs on the 15x8s is 4.5inches.

Anyone that has a 73 or 74 RR and can comment on how 15x8 mopar rally wheels with 275s fit please let me know.
