Is anyone running this size on the rear of their car ? Be interested to see pics ? Also what backspacing would be needed ? I have a 70 Charger with 4” backspacing on the rear, thanks
I've run that size on a '64 Savoy wagon, and the previous owner of my '69 Road Runner did as well. Both used 8" wheels with the stock 4.25-4.50 BS, no rubbing. That tire is about 30" tall but not all that wide - I've run 295/50s on a RR before with the same size & BS wheel with no issues.
Sidewall bulge will be different than what I know about, but likely not much. Look up the section width, see what rim width it was measured at, and compare to what you have now. A straightedge and measuring tape might be handy; straightedge against brake drum, measure to springs & inner wheelhouse.
I run those on my 68 Satellite . I use a 8"rim with 4 1/2"BS . 7"rim will be fine , yes a little more bulge . Good size tyre without looking oversize . Great with my 4.10s
That's what I have on the back of my Cuda at the moment. 15x8 wheels but the offset is not optimal. Tight to fender lip, but plenty of room on the inside. 255/60 on the front with 7" wide wheels.
I was just thinking of having 255's put on some 15x7 rims for my 1972 Charger. Thanks for posting pics everyone, all your cars look sweet with that size of rubber.
Interesting post . I need tires this week to get ready for Lebanon Valley Mopar shows Sept 5th and Sept 12th . 69 Coronet with 15 X 7 old school American Racing Torque Thrusts with cooper cobra 275-60-15 on rear . think I'm going to try the coopers in the 255-70-15 especially since I have 7" rims . . Nice pictures on all the members cars . Have a great , safe Labor Day . Ronnie
Hi Moparts , update , I did get my new rear tires in from cooper in the 255-70-15 size , and they are perfect compared to the 275-60-15s i'm replacing . The next question is cooper changed the Font of the white letters VS the old tires . and the new tire letters look bigger and slightly slanted . Here we Go , New White letters out , or Black Side Walls out using American Racing Torque Thrusts Rims mounted on a dark green 1969 Coronet with black vinyl top ?

Black walls out would be my choice as I'm not a fan of white letter tires on aftermarket wheels. However, I do prefer white letter tires on factory rally wheels.
Thanks. I'm considering that size tire with a Torque Thrust 15 x 7 on my 67 Belvedere but the backspace is limited to 3 3/4 in that wheel width which may prove problematic.
Hi Belverdere , I just measured mine and second the measurment backspacing of 3 5/8" to the rim flange and 3 3/4" to the outer rim Lip on my 15 X 7s rear Torque Thrusts . Happy Labor Day weekend , Ronnie
