Input on a possible tire failure?

[SCORCH]

About a month prior to rotating my tires a while back I noticed a slight hop or vibration while driving around 52 mph so I decided it was Definitely time to rotate Especially since it had been about 12,000 miles since the last rotation. Since rotating them the hop has gotten considerably worse and now shakes pretty good at nearly all speeds but is more noticeable when you just get going when the tires are a little colder (unless I just get used to it). My truck is a 2007.5 2500 HD Silverado and I am running 285 75/16 on the 16 inch stock 6.5 inch wide wheels. Tires were rebalanced about 30,000 miles ago then we realized a slightly bent rim might have been the issue. The bent rim was replaced about 10k miles ago. 

 

The local discount tire will take the wheels off to rebalance them but said once they are off they will refuse to put them back on because those tires are way too wide for the wheels. They said one or more of the tires went bad due to the width difference of wheels to tires. How likely would this be? I thought people ran 285s on these wheels all the time...

I did a quick check on Tire Rack and it looks like that size of tire is made to go on a 7.5- to 9-inch wide wheel.  Of course, folks use beadlock wheels and wider tires for off-road use, but running regular wheels and too-wide tires on the street (and not rotating the tires every 6000-8000 miles) is a recipe for the tires to flex more and wear badly (depending on the quality of your tires too), both on the tread and the internal structure, hence the "hop" you are experiencing.  There are more tire dealers becoming real sticklers about what they'll service, based on the potential liability of if someone hurts themselves and then turns around and sues them.

Scortch, I am a newbie here, I have been a tire dealer in Florida for 40 years, I will probably get hammered for what I am going to say but I can handle it. I am not an engineer but I have probably installed, myself,  over 50k tires  and balanced twice that many over the years. When I started at my shop we grew up on Truing machines and on the car balancers so I have looked at separated and OR tires in my life. Of course the problem as the industry not wanting to handle tire issues, it is a PITA, all the paperwork. The manufacturer sure does not want to label it defective because of recall potential, call the manufacturer and ask for a goodwill adjustment. They code Goodwill with a 7 if my memory serves me right. Whole different way to the FEDS then,  National Tire Tread Safety act brought on many changes except the real problem  that I felt was to put an expiration date on tires. Anyway, call the manufacturer ask to take to another a dealer who they recommend in your area. I would help you out if you around me. The previous guy is correct about the legal aspect although I have looked at a lot and sat on the stand quiet a few imes but have never heard that as a cause of failure, maybe center wear but not failure. Again this is just my recommendation. Good Luck with that one. David
