Stumped by new Tires
So, I changed my China made tires this season and purchased Hancook, which I liked but was not sure after a couple of trips. Ever since the change of tires, when I get to 55 mph and above it would vibrate the coach, to the point that i was having to slow down.
I was convinced that the balancing of all 6 tires was the cause..so I had them rebalanced at another garage, results!...better but still not a smooth drive.
I then take it to another level and return the hankook and upgrade to michelins.
Well again a bit better at those speeds but still a vibration that makes the higher speeds very uncomfortable on long trips.
Now I know what your thinking..suspension! Well all shocks are new and air bags.
So my question is? One that was brought up to me...Alingment! now would that correct a vibration?
Breakdown of the coach
Diesel ...38' no tag Coachmen, 18 years old and I am the third owner.
Thanks in advance

I don't think an alignment will help with a vibration.
I know I'm reaching here but have you considered having the driveshaft checked for imbalances? if the PO replaced a u-joint incorrectly that would cause your symptoms

I see where your going, but it only happened once I changed the tires..to what I think is a premium brand! Two times!

Thanks a great deal for getting back and reporting what your remedy was. So many times, we never know if a problem got fixed and or, what the original cause was.

Being that the coach is 18 years old and with no history of maintenance, I am still going to have it aligned.
For what you pay for rubber, I am not taking any chances.

Coming from the trucking business....do not be afraid of Chinese made tires...we run them all the time, successfully I'll add in our line of work. I cannot stand to pay good money for dramatically over rated and over priced ragged Michelin tires that dry rot before wearing out.
It's not a bad idea to always consider spin balancing at the time of purchase/installation. It's a cheap form of insurance to ensure a smooth ride and good wear.
Enjoy your ride and be safe.

At 20,000 miles on my Michelin tires on a 2015 coach, Dynabeads didn't stop the vibration on the front so I had a truck tire shop remove the beads, spin balance the fronts, and install Centramatics. Still get vibration 55-65 MPH. Going back to the tire shop and have them rebalance the front tires.

Wagonmaster at least one tire isn't round.

Out of round was one thing I was concerned with, and tried to watch the tire tread as it was spin balanced but couldn't see anything obvious. And the balancer didn't say anything about it either.
This is a small tire shop but they do a lot of semi truck tire work, but I may have to go to a large truck shop in a larger city, maybe even a Michelin Truck Tire Shop.
