I'll take the thicker sidewall construction anytime. Nothing worse than on winding roads or crosswinds the mal de mer feeling the flexy sidewalls have, especially if not up at max pressure.

6000+ Foretravels new disagreed as did cm fore when he told me they had tested multiples of every tire made when the unihome was introduced and like the Europeans did they built the suspension system and settings around the tires.

From the horses mouth. I was there in OCT 1987. In Nac.

You may not feel the difference but I have and can.

Some of my observations are related to the now legally defensible looser front wheel bearing adjustments.

Mine were preloaded. Zero dead spot. Now .001-.003 and a slight dead spot.

The Michelins design includes a self correcting edge sipes to bring the coach back to straight.

The others do not.

Wheel bearings are now looser by legality requirements.

If you could drive the coach from the bottom of the steering wheel on a long demo ride I sold more motorhome for a higher profit.

Same as foretravel as a factory,

The tires accentuated the already superior ride and handling the eight air bag and Koni shocks delivered.

My two cents.

FMCA offers a couple brands. Not just michelin. All the hoopla over them being designed to do "xxxxxxx" does not sway my decision to never run michelins on any rv I own. They explode often and with expensive consequences. My current non michelins will be replaced with even cheaper non michelins that I hopefully will be able to wear out in 10 years!

Funny you mention the beads. I have not seen them but years ago I was

at a tire store and there was a trucker there getting new tires. He had a

plastic bag full of golf balls and put a certain number in each tire before it was

mounted. He said it kept them in balance. Guess he knew what he was doing??

Stated this on previous post but I still think some of the minute steering problems we have are

Found this out when redoing mine,had to lower and raise coach to get bolts out.

My personal opinion (which means hoot to most I guess) is that today tyres are fairly equal across most makes and all this crap about one make being much better/safer etc than all the rest is just that!
I look (as cashflash bob said) at trucks etc at fuel stops just to see what these guys like and now it is all over the place including offshore makes so that does not help me.
I would imagine that just as other manufacturers do they get a special pricing for volume and this was the motivating thing for CM Fore. I cannot see them building a few coach's then changing tyres to see which gives the better drive. This is all done by engineering people prior to final build. Input by a large manufacturer like Michelin wouls sway most.
Europe for many years used Pirelli on new cars and now use others. reason for Pirreli was that they are softer rubber and your car used to "stick" to the road making you think the road holding is superb.
I can guarantee that FMCA does NOT think that Michelin are better than all others for your Motorhome it is that Michelin are willing to give members a break on the over priced cost and other makers are not. I see Continental now are also "prefered" so how does that work in the equation? Gather CM forgot to look at them too!
No, Bob it is all marketing and you cannot get me to believe anything else sorry and I will merrily move on down the highway with my Toyos on front.
Oh by the way FMCA I guess does not care about the lives of its Canadian members as they do not allow us to buy thru' the Michelin Program. If these tyres are so much safer surely FMCA would open it to us (still would not use it mind you)

Howdy gracerace,
That's a good price! I'm wonderin' if you had Gs or Hs installed?
Thanks for sharing, Dave A

They are 'G' rated. We talked about H's, but we didn't feel the coach is that heavy. If it was a U320, maybe that would have been a possibility.
H's were not that much more. I don't remember the quote.

Suspect the "what divisions of Michelin offer the program" was strictly a Michelin decision. FMCA is quite aware of members on both sides of the border.

If I were looking to buy steer tires, the tread pattern plays a role in whether that design are easily damaged under normal use. This is what a local tire expert told me.

Whoa. That's a deal. Did you have some kind of prior association with them, or was this a deal you walked in and negotiated?

We have bought quite a bit of stuff from our local dealer over the years.Tires, wheels etc., because we have a few collector cars.Nothing like a business would buy.
I just talked to the manager. One tid bit is, a mutual friend to the manager,who works for a large company who buys a lot from them, called and got the brother in law price before I went in $3200.00 OTD. I just talked nice, asked for his best shot, $2100.00 exchange is what he gave me. I would have sold the tires on craigslist, but it was snowing already, didn't want to mess with it. Probably could have gotten $150.00-$200.00 ea.
He also told me the Michelin's we had looked great, but I talked him into selling us new tires, because I have seen so much damage when tires come apart. Both customers coaches, and my own. 10 years fronts, 7 years back, was just pushing it for me, no matter how good they looked.
He had some other off brands I never heard of, even cheaper. A couple were H's. But because of the lighter weight of our coach, we both agreed G's would be fine.

A lot of factors are involved in tire failures. The rated load printed on the tire is only at the specified pressure. Pillow soft pressures together with summer heat and pot holes shorten tire life. Don't ever let air out of a tire in hot weather. Winter storage without raising pressures and taking some of the load off the tires also contribute to the chances of a failure.

How do you engineer a truck front beam axle, rigid axle or solid axle around a particular brand of tire? Another wives tale.

Yes, tires in Europe have to be specified according to the top speed of the vehicle. As the speed goes up, so does the tire weight plus the compound is much softer and stickier. No, they don't last as long.

Lots of good info. Almost every blown up tire I had in 15 years in high line Rv sales management had, upon inspection, rusted cord belts visible on the inside.

Non dry air...

Use the coach air output after raising your D2 pressure to 110-130 on and off.

No cute little compressors unless you have an air dryer after it...

Country coach had Les Schwab mount up double sets of everything available to test their first IFS coaches with the proviso that CC would order their production tires from them.

Foretravel did the same thing in Nac.

We could have a labor consuming tire test if anyone wanted.

Did this several times on my lot with older coaches

Lots of volume in those days to use for testing. 1988 I sold 41 used. 59 new.

Be safe.

Caster and camber I think were the settings done for the specific tires.

Shocks were set at 1/2 turn originally and most were reset to 1 1/2 turns. At least in my store after a bit of driving.

FSD's are a component here I feel.

Had many spirited discussions with highly opinionated owners about tires 30 years ago, which is good.

We had a spare, canvas wrapped, on the roof when we bought the coach. Since I've blown a spare that scared the pucky out of me, I took it down and threw it away.

Exactly my point Brett, this was not an FMCA decision based on "better tyres" but a marketing issue by Michelin, that was my point on Bobs comment about CM picking that make over others equally as good.

Cm and boney Moore and don shipe all drove personal unihomes and switched tires on coaches to test them..

Hated cm's as Marie like green. Gag.

Customers asked why their demos did not have the std tires.

Testing.

I run Michelin in the front and Toyos in the back. The fronts cost as much as the 4 in back.

I just put Toyo M154's on the front in November. I have not seen any evidence that Michelin tires are superior and worth spending hundreds more on.

Having the same tires on the front as the rear is as important as having matching Kleenex boxes inside the coach.

As long as the coach is weighed on all four corners, so as to know tire pressures, you would do fine with any tire, for a while.

We went from LRG BF Goodrich to LRH Michelins last summer. Better ride, better in the wind, better noise, better feeling safe. No idea if any other tires would have done the same. There were almost the most expensive by about four tanks of fuel over six years compared to the cheapest tires. I am rotating them so that the steers are never more than three years old. We are doing what makes us happy as my friend Dave M often told me. I think he knew what he was talking about. Bless his heart.

I would take a look at Hankooks. I personally after having a sidewall blow out on brand new factory Firestone tires would not even put them on a wagon. I'm running Samson's right now and will look at them and Hankooks when the time comes.

Round, black and suitable construction for the Intended purpose. All racing sports cars balance the available traction on each end. Doesn't matter what tire supplier except for the fact that you don't get any sponsor money unless they match. Depending on the venue Left compound might not match right, or even 4 different compounds. Back to the coach aspect the front's don't need to match the backs as the tires have no clue whose tire or even what diameter, traction coefficient, or pressure within reason. If your to point that you have to worry about understeer or oversteer change your driving habits. Soft compounds may be a safer as our tires tend to "age out" before they wear out and may save your bacon. Just my 2 cents worth.

FMCA now offers Continentals as well as Michelin.

Does not matter if rear tires are different from fronts. Put same tires on front and make sure that they are rated for the weight. On dual sets match tires on each side so that they are the same diameter otherwise the larger tire will be bearing more weight. There are a lot of factors affecting the loaded and rolling radius of tires but making sure they are of the same height is good enough for our purposes.

I think Michelin are over priced especially for RV use. So long as you say within the tires speed rating - most large tires are rated for 75 mph - you will be OK. Main thing is keep to the required pressures.
