biggest tire for 15x4-1/2" rim ?

Thank you very much. I've got 4" wheels so I may look at the 205/70R-15 as a option too.

Not sure of the brand. Just something cheap I bought at the local tire store.


And in response to the fellow asking about the "57 Ford", I like 57 Fords but this ain't one of them!

 

BTTT for others .......

 

Not trying to steel your post 31Vicky with a hemi but I have a question related to the skinny rims.
Does anyone have a measurement from the spindle to the outside of the tire on a Torq-Thrust II, Aluminum, 15 in. x 4 in., 5 x 4.5 in. Bolt Circle, 1.50 in. Backspace?
Trying to lower the front of my 46 and I don't have enough clearance with the current combo.
