I just pulled off a set of Yoko Geolander H/T tires I installed on my 1997 Expedition 4x4 EB about 4 years ago. I don't drive alot, so they had only 20k miles on them, but were starting to get noisy and shakey. The other day, I was about losing my dentures with the rear end bouncing, so I stopped and got out to look and see if I had picked up a stone in the tread or something, and to my horror, the tread was beginning to bubble and separate from the right rear tire. I was about ready to blow out!!!

I hustled over to a nearby Goodyear tire shop to put back on the original Wrangler RT/S tires that came on the car new and performed very well for almost 60k miles with a nice smooth ride and good traction. The Yoko's never balanced right, were always noisy and harsh riding. After riding on the Goodyears again, it's like a pillow under me.

I've had good experience with Yokohama passanger tires on my BMW's, but this truck tire was a disaster waiting to happen! How many fatalities have occurred in big SUV's when the rear tire blows? I feel lucky that neither me or my wife, who uses the car a lot too, didn't befall that tragedy.

Maybe other models of Yoko truck tires are better, but stay away from this one....thank God it's been discontinued in this size, but if you have them on your vehicle, I'd be very careful and monitor them for belt separation, increasing vibration, or unusual wear patterns. They were a lot cheaper than the Goodyears or Michelins, but not worth a dime. Plus, the Goodyears are made in good ole' USA!

 

After reading this I'm wondering if the Geolandar A/T tires I put on my truck are the source of a vibration I'm having while braking. I've tried just about everything - new rotors (turned on the truck), new brake pads, tires road force balanced, new front shocks, had the truck on a frame lift and the suspension seems OK. Any suggestions? Could it be the brand new tires??

 

Vibrating only on braking and not while normal driving should be isolated to either a brake or suspension fault...not tires. Warn ball joints, loose brake calipers/pads, warped disks, or even burned disks (can happen after really hard braking-the pad heat-soaks the disk in one spot and creates a blued area with different friction coefficient.) I know all this from my BMW enthusiast driving days (which I used the truck to tow my track car!)

The tire problems I experienced, such as out of round defects or finally a tire failure due to belt separation, would be felt at various speeds regardless of braking. I think your model tire is a higher quality than the HT, which was discontinued.
