69 Barracuda Front Tire Clearance Question.

You've got to compare apples to apples.

What is the backspacing of the rims the people above have mentioned?

I've put 235/60/15 up front with 15x7 4.25" backspace rims and it was very very close on the bottom front fender lip.

There have been people here that have run 225/60/15 with 15x7 4.25" backspace rims and had bad rubbing while backing out of driveway and turning.

Alignment, thickness of rear strut bushing, past collision damage, and small bolt pattern vs large bolt pattern are the major things that will effect that last little bit of clearance.
