I run the 20 inch Toyo's and am on mid perch. I also hit railroad tracks every day. Though I cannot be sure if the grade is anywhere close to what the OP stated, I don't get the bounce. In all honesty though, I have had 20's on since day one. I think I drove a total of about 25 miles before I swapped the wheels and tires out.
