If you decide to install 14 ply tires such as the Sailun or the Goodyear G614's, make sure your rims are rated to handle 110 psi pressures. All rims are not. This is the issue I'm struggling with now. I haven't removed a rim yet to verify, but I'm afraid my rims are not rated to the 110 psi.
But you are doing the right thing by asking lots of questions from those folks who have traveled the same path you are on now. I've learned a lot from these guys. Let us know what you decide to do.
