THE TEXAN, as you say, everyone has their opinion. However, I would say not many in the world would share your opinion on Michelin's quality.
I started running Michelins on lt. truck tires back in the 60's, pass. tires before the American cars were converted to compatible suspensions for radial tires; heavy truck tires for 30 years. I have yet to have A SINGLE PROBLEM that was not my/our fault. Maintenance of any brand is the key to success, but the product must be right in the first place. Michelin's quality is right.

My father and I both had terrible luck with Goodyears (670's)5 blowouts combined in four years on tires no older than 4 years old. Both now have Hankooks and no issues for a combined 10,000 miles.
On the older Ford v-10 chassis (8 lug) they had problems with centering the wheels and you had to go through extra pains to make sure everything was seated right. There was a TSB I believe. As stated earlier by another poster.

I don't think the problem is the tires, it is the installer. NO WAY should you be running your tires at 65 lbs. You should get each tire on the RV weighed with RV loaded and your gas, water and propane full to determan correct pressure. It is better to run with a little higher air pressure than to low. I have the same size wheels as you and I run my Toyo Tires at 110 lbs. The Ford steel rims are sometimes hard to center. You might have better luck at a truck stop than an RV center or regular tire store.

First. You can't just look at a coach and determine correct tire pressure. You need to do a 4 corner weighing and determine the correct pressure for each axle, based on the highes weight (left or right) for that axle.
Second, you should be sure that you have a tire that is adequate for those axle weights. Every tire manufacturer has wgt/load charts for each line and size of tire. Go to their website or call their support number.
Third, you need to pay attention to alignment and tire balancing on the front tires. You also need to be sure that you have either steering tires or all-position tires mounted on the front.
Finally, it might be useful to read my notes on tires in my sig line. I did a lot of research when I had to replace tires two years ago. I'm no expert but I think I got good information.
Good luck,

I doubt its a Brand specific problem.I bet its a mounting,balance or installation mistake of some sort.Possible one bad tire maybe
Are U sure they balanced the rears.and 65 lbs is crazy low pressure

All U need to do is go to a Tire shop that specializes in highway and gravel trucks etc and they can set your pressures without all this weighing bullcrap

I never have been able to figure out all this BS about weighing all four corners. First of all most RVers don't really carry anything really heavy on the coach. Maybe a tool box would be the heaviest, other then that chairs, bikes and a few other stuff like bbq qrills. Nothing really heavy to make that much of a difference. I drove many railroad five ton trucks that carried railroad wheels which are heavy and we never had to weigh every corner. Some of these posts make me laugh.

When I put new Michelins on my Allegro Bus, I pulled onto the Interstate and had a terrible vibration. I pulled off, called the truck tire installer where I bought them and told them of my issue. I had them, during the install, place the silica balancing bags in every tire. They suggested I needed to drive a few more miles as it takes a while to actually break the bags containing the silica. Sure enough, I pulled out onto the Interstate again and the coach was smooth as silk. Not sure how your tires are balanced but wanted to add my experience to the fray!

I hope both guys with problems running Hankooks get their issues resolved. To save a few bucks and end up with a bad ride or vibration at certain speeds is no deal in my book. I'll stick with Michelin.
