I am runing a set of 17" on my dart. Right now the tire size is 235/45R17. I will be going up to size 245/50R17 next time. Plenty of room. Here is a web site that breaks down all of the tire measurements. It has really helped me find the right tire sizes for all of my vehicles.

These are not mine. I found this on Maketplace. Cars are in Quartzsite, AZ. Ad says $12,345 for all four cars.

No pics of all the cars, but they might be in good shape for projects.
Installed my new 17" spare tire. It is a 135/90R17. Fits like a glove! I have a 1 inch adapter to go from SBP to LBP. The adapter fits under the foot for the bumper jack. The trunk floor is now flat across!
I figured out how to make a baby moon hub cap for wheel that doesn't have any provisions for it. I took a Crown Vic police interceptor hub cap and welded a slightly modified GM restoration smoothie to it!
I even tested the finished assembly on the road. Tested on the front and rear wheels...

Not sure on cfm. But it says it supports up to 350 hp. Works great for my little 318!
