I came across these pics of this truck on this forum and am trying to figure out what tire sizes he is running! If someone knows or could guess I'd like to here it.

I know that the wheels are 15x7f/15x10r but I can't find a decent tire for the 15x10's.

I've seen people run 275/60r15's on 15x10's but they look to be more stretched than his are, I'm trying to stay with the stock od diameter of around 28 inches but wider than the 275/60, it looks like 325/50r15 would be the perfect tire but I am only able to find them in drag radials.

What do you guys think?
