Back in 2009 when we bought our first used Gas Ford powered MH, it came with Goodyears tires that really needed to be replaced. We made a few trips with the Goodyears, all over the road.
We finally got the new Hankook AH-11 tires mounted. Man, what a difference in the way it road and over all better stability over all.
and in 2014 I bought another Ford MH. It already had the Hankook AH-11tires on it. I drove the MH for another 5 years with those same tires.
The only really bad handling problems I ever had was with the side winds, and trucks passing by.
