I would like to pick your brains, rather than try to reinvent the wheel (fit). In the past I have struggled greatly, and spent countless hours, trying to figure the fattest and tallest wheel/tire combination that I could stuff under my late '31 Ford wide bed pick-up (skinny fenders) and a '30 Ford coupe. Now I am considering purchasing a '31 Ford Tudor sedan, and would like to minimize the "suffering" related to buying the right wheel tire combo. If you have any suggestions or have been successful with your own decisions, I would appreciate your comments and suggestions. Many thanks. Joe josephaltieri@att.net
Thanks. Maybe my terminology was poorly chosen. I'm not talking about 12-16 inch wide tires, I am looking at something in the neighborhood of 7-8 inches. And no, I am not looking for "wagon wheels" either. My coupe runs 15 x7 and 16 x 8 inch wheels and my truck ran (just sold it) ran 15 x 7 all the way around. Both had VERY tight clearance. I guess what I am saying is that I would like taller, rather than fatter tires. (In the early 50's we ran a lot of 6.00/16's on our cars!)
I'd say given how similar the fenders are on the A's and the amount of tweaking that has happened in the last couple decades that the closest to a correct answer your going to get is take the biggest that would fit on your old cars and measure your new car to see if it fits. Your going to mainly measure width of the inside of the fender approximately were you'd like the top of the tire to land. The height is going to be endlessly variable based on where your rear axle lands. Is the car low or tall? The lower it is the more you pay attention to the width of the tire opening. A 750:16 is going to land you about 31 tall if I recall correctly and that's about as tall as your gonna get stuffed in that car most likely. As far as width a 28/29 sedan back fender is around 7 wide. So I wouldn't plan on much tire being stuffed under the fender before it either sticks out or hits the side of the car.
Here is a 28/9 with stock rear fenders with 750/16's and you can see that it's a tight fit all the way around. They could be tucked in a little tighter to the body with a narrower rear axle, as is they rub a little when throwing it side ways and a narrower axle would land them under the crown of the fender a little better clearence wise
