Yokohama tires not happy

Yokohama makes a great tire. But I had 285 Yokohama's and experienced sort of the same thing you did... they felt fine when not towing, but soft/squishy when towing and seemed to have a lot of flex, but they did the job while I had them. I have since replaced them with Hankook DynaPro ATM 285/16 Load Range E, and these are much better, everything feels much more solid. The ride is stiffer even when aired down and not towing, but I don't mind that at all.

Tire squirm ,look at the linc that T&P posted ,happened to me new rears felt like ball bearings under the tire .
I didnt wait to see how long it would take to stop, I rotated them to the front and problem solved.
That was with my former SD 7.3.

My tire dealer has told me that it will take 500-1000 miles for some tires to "break in". I would wait and see if they improve as you get towards 1000 miles on them. Yoko's have a very good reputation, so my money is on the ride improving with miles.

One time I had 6 brand new tires put on my 2001 F350 Ford Dually and that thing was all over the road. Took truck back to tire store and they checked everything out and readjusted front end to no avail-they ended up getting me a different brand of tire and that took care of the problem.

It was so bad that even a car passing me I could feel the pressure and make things go squirrely.

Here is a little reading for you.


A little info about tire squirm.

Yes, 75 psi on all 4 and I have about 350 miles on them now.0

Yes that is correct. I am wondering how it would handle if I were to rotate the BS to the rear,and put the yokohama's on the front until get home. Let me tell you it was a white nuckle ride to TN from ohio.

As said above, make sure they have the right PSI and give them a few hundred miles.

It sounds like the Bridgestones are still on the front end. And the new Yokohama tires are across the rear. If this is so, as crazy as it seems, some brands of tires don't work well with other brands.
