Ok, that makes sense. A 215/70/15 is almost 27” tall, which is really tall for the front. With a passenger in the car it’ll sit lower, so, it’s also ride height related. The height is the issue with those tires and not so much the width, if you keep the height close to 26” you can probably go wider. All depending on the backspacing of course, but a 225/60/15 fits easily on an E-body with the right backspacing.
