can anyone tell me {a Novice at this } how to size the right wheel tubs for my 54 panel, I have a fatman tube chassis with a narrow 9" rear set up for 33x21.5x15 tires also want to lower the truck.

 

Need better information. Wheel size, tire size etc. The largest tub you can install would be from the inside of the body to the outside of the frame.

 

thanks. I understand but was not sure how much clearance i should have Top, Front and Back of tire. I have not purchased the tires n rims but do have sizes written in a log I sent to fatman so they could build the chassis.
