You have 2 pgs off folks saying get a second option which is good advice. What I would do first is to jack up the front of the MH first and put a flat piece of wood under the tire and then rotate it and you will be able to see if tires are out of round and how much. For your tires to bounce do to being out of round you should see 1/4 in or more.
Don't know where you got the idea that 1/4" or more is the lower limit, but your high by a factor of 3X or so. A tire that's out of round by 1/16" or less will be quite noticeable. I just had a shop true (lathe) six Goodyear tires on my MH. One was radically out of round, in excess of 1/8". The others were out by much less. Removing defects much smaller than your 1/4" will make a radical difference in how the thing rides and rattles.
I "got this idea" by measuring how much the my tire was of round. The OP describes "front wheels bouncing baldly" a tire that is within a 1/16 won't do this. When my mine were under 1/8 in the bouncing ceased but was still very noticeable. I have not been able to find anyone in Ct. that still trues tires but that is the best way to get rid of out of round tires. Even brand new tires can be slightly out of round.
Sorry, but I still strongly disagree. If you have a tire that's 1/4" out of round, you are at the outer extreme of totally defective. Truing a tire of this caliber would mean leaving areas of deep tread and others with little remaining, or even wear bars showing. But, you're relying on the OP's definition of "bouncing", whatever that means to him, and he is no longer contributing to the thread.
On my 2006 F53 chassis, an out of round front tire, well below 1/4" out, not only created a horrendous ride, and extreme vibration through the entire coach, but it also created oscillation and vibration in the steering column, and seat which certainly could be described as bouncing. The experience was similar to driving down a set of railroad tracks and bouncing off of every tie, once the thing hit 40+mph.
