Huh? How do the tubes affect the tow vehicle?
My rig on the trailer as follows: Boat strapped down tight to trailer (ratchet strap over the motor pod [equivalent to a couple of tie-downs from transom to trailer], bow strap cinched up tight, safety chain on bow eye and shortened, additional ratchet strap from bow eye straight down to trailer to stop the nose from bouncing.
Tubes generally get softened upon pulling from the water, primarily to avoid overpressure from solar heating. If I pull the boat late in the afternoon with an upcoming night tow, I may not relieve pressure.
I agree that you should avoid over-tube straps if you can at all avoid it. Wear is one issue, the other is a false sense of security: tubes are pliable, and anything that tries to move the boat from the trailer will put a lot of force on the tube/strap junction. Once the tube fails, your hull is no longer tied down.
