Don Hay cannot get on forum so I posting. Put toyos on rear, pressures equal all four duals but coach seems to be fishtailing. Less on interstate. Temps different inside vs outside duals. Tow bar ok. Not toyos on front.
Air bags ok. I wondered if problem if steer direction mounted wrong but I have no other ideas.
If you send me ideas I will call them to our friends don and Trudy
Thanks in advance, mike
Boy that's a new one .
New since tires put on ?
Broken track bar ?
Loose lugs ? On Don's the inner dual is held on with BUDD Type stud.
Loose or broken air bag mounts in rear ?
Loose steering components in front ?
Can Trudy follow in car and relate to Don what she is seeing ?
As Mike said, Steer type tires on rear mounted in wrong direction ( very unlikely ) ?
Where is DON ? Anywhere that any of us can contact and assist ?

It is normal for inner duals to run hotter than outers, as there is less air circulation there.
And it is also not uncommon for brand new tires to "squirm" a little until broken in.
Have Don try adding another 5-10 PSI to the minimum recommended by Toyo for his actual weight.
He doesn't need extra fishtailing coming up the canyon.

A deep agressive tread will add to the wiggle / fish tale effect, low air psi will also produce the effect, as wolfe sez, pump em up to at least max side wall info
Thanks very much, I will call with what each said
He amarillo tonight Bret then canyon Sunday
Mike
Told don. He talked tire folks, agreed it the aggressive tread. Told him they seen before and get better in 500 miles.
Mike
Any extra play in the front wheel bearings will accentuate the fishtailing that may be part of the tires design.
Evidence of this is a "dead" spot in the steering. Mine used to have it. Long term Foretravel mechanic friend redid the front seals and re tightened the front bearings and no "dead" spot anymore. Small steering wheel movements are 100% transferred to the coach.
Yes I have long ago driven coaches with toyos that wiggled. Especially on grooved roads.
Coach was designed around michelins.
:o They never get better, you just get used to it.
NEVER put aggressive tread on the rear of a single axle short wheel base, I made the mistake on our crane truck as we get off road setting generators, now we just live woth it, but no fun to drive on the interstate.
