Re: the largest tires i can run on a 69 with 16x8 and nuetral b/s
are the rims on the car already?
I ask because a "nuetral backspacing" sounds like it would be 4"
it would be hard to say what the widest you could fit would because most of us here with 8" wide rims run 4 1/2" to 5" of BS
or atleast thats what i have gathered,
my 16s are 4 3/4", and have 255/50R16
oh and another problem with 16s is that there are not enough tire sizes out there, 255 is the widest i have found
if you want 275, they will need to be 30" tall, that would be quite the sweet rake (and it could help the front not be taller than the rear)
