Tire size
 

Hello Moparistas,
I have a question for you, what size would you use for a rear tire on a 1964 Dodge Polara? The rims are 15x7, I have Hi-Jacker shock absorbers (the car is raised a little at the back because of this) now I have 275/60 ​​r15 rear tires, unfortunately when someone is sitting in the back seats and I drive over a pothole, the tire cuts slightly on the wheel well, mainly towards outer part of the fender. Wouldn't it be better to use 255/60 r15 tire dimensions?
Thanks in advance for your answer!

Are the wheels 4-1/2" back spacing ?????? If so, From what i have seen... The 275/60R15 should work without issues????

I dont know what is backspacing.. in czech language we havent this wordl 🙈😅 try to explain to me what size is meant by that..
btw.. the wheelbase is 5x114,3 mm

This should help.... :)

Looks like the 114,3mm is the 4-1/2" back spacing... If this is correct, then you will need the next size narrower tire to keep from rubbing.
