Duke,
One thing to watch on semi's like those is they pick up and throw a lot of stones, if the tyres are protruding from the lips of the guards they will throw the stones onto the body work and you get small stonechips on the bottom trailing edge of the wheel arches at the sills. If you get some clear 3m automotive film you can protect those areas.
I have run the falken azenis on the alpine for 6 years and whlie they are great they are noisy and have the stone throwing issue (though i am running narrow tyres in comaprision so not an issue on those) and the dunlop dezerias I have found better.. better in the wet, quieter.. but the super soft compound has the stone issue...
just a heads up.. make sure your paint is not in harms way!
