I am looking at changing to a 19.5 tire, I have a 2013 with stock ride height. I have searched for two days and can't find out if a 245/70R19.5 tire will fit without any mods, I could go with a 225/70...
I went with a zero offset on my '06 Dodge 2500 diesel. I needed a 2" lift in the front for the 19.5" 265's but the 245's fit without the lift. My 265's are Toyo M608Z and are 34.4" tall and 10.2" wide. I think I needed the clearance for the width rather than the height.
The M608 in 245/70R19.5 are 33.2" tall and 9.4" wide.
