I have a 32 coupe full fendered with a 9" ford rear. Backing plate to backing plate is 52.25". It has drum brakes. I would lik to know what the tallest,and widest tire, and rim size recomendation would be? I am ready to set my ride heigth.  PLEASE HELP!!!  Thanks Jon    

I wouldn't consider myself an expert, but I think that there is alot of things besides the ones listed above to take into consideration.  

what dia wheels are you going to use/offset and other items are going to need to be considered..Last night we fit in the rear end into our shop 32, running 29/12.50/15 tires in 10 inch wide torq thrust wheels,but rear end had to be narrowed to 48.5 overall and inner panel moved in 1.75 inches on each side
