Thanks Jim. I used a similar site to compare and the width increases from 10.8" to 11.6", the height increases from 37.7" to 41.1" and most importantly the sidewall increases from 7.6" to 9.3" for a 22.4% increase. I will test the fit tomorrow as the tire shop has promised to work with me to make sure the fit is ok.
I was concerned about running a larger steer tire than drive tire, but Source Engineering and the tire shop both say it is ok? The new tires will reduce the current 18 ply tire to a 16 ply and also allow me to lower my tire pressure on my 10,000 lb front axle to 85 psi.
Theoretically, the new tires should help to take the "harshness" out of the front axle? I am concerned about the appearance of the tire combination, but I am willing to trade appearance for performance. Hopefully someone that has made a similar switch will let me know how it worked for them.
