No big surprise here.
My 69 GTO has the standard 14x6 Rally IIs all the way around.
No problems with P225/70s on them.
Rarely, with 5 people in the car and hitting a decent bump at higher speeds, a quick bottom out has occured. (I plan to stuff drag bags in to maintain more height and correct this- it spends its time taking the kids out for ice cream, etc. and not at car shows or the drag strip)
I think they are a great tire up front.
I want a little more height and width in back.
I am refurbishing a pair a HM code 15x7s for the rear.
Plan to 255/70,
275/60,
or, if can find, 265/65 and see how it works.
(Goal- slightly increased diameter to decrease rpms while crusing, and a touch more raise to the rear end, and a little wider tire than the 225s.)
Here are the
225/70 14s all the way around.
