I was confused by that as well..

Do we have a Blue Jay too?

A retired Goodyear engineer at an Escapee Boot Camp did mention not to park your rig long term on concrete. His solution was to put a cheap plastic placemat under the tires. The problem, as he related it, is that black mark that is left when the rig, or car moves after sitting on concrete for a fair amount of time. According to him, the black mark is an ingedient in the concrete leaching the anti-aging chemical being leached out of the tire.

As I did with our 2005, taking our new 2015 to an alignment shop next week. It is critical that your trailer alignment is right on or you will be eating tires every 2 years.

MLH//It got me for awhile also.

I wish this old myth about "parking on cement is bad for tires" would finally dry up and go away already! It's silly, it's wrong, and it needs to finally die.

[DQDick]

That said, what explains the black marks?

Question for the OP?

Did you have a TPMS on the tires? If not, how do you know the tire that blew out was not at a reduced pressure, and that is what caused the tire to blow.

OK, you always check them, but you can pick up a nail or screw 100ft down the street.

So lets review, a ST/China tire with no TPMS blows out and you want the RV Dealership that sold you the RV 2 years ago to buy you some tires.

Folks, this is not rocket science, good tires and a good alignment equals good tire wear, nothing else.

I understand your pain..... no condemnation here...just sympathy. The person responsible for my selection of a Montana as a full time rig, is looking to upgrade to bigger rig. When he asked what my thoughts, after having levelup system and other improvements over his year. I said "no unit that weighs greater than 14000 lbs. On the Gvwr sticker should leave any Dealer lot without electric hydraulic disc brake upgrade installed. Then go to a tire dealer and get the OEM tires off the rig and install the proper weight rated tire." I believe that any dealer that doesn't tell a customer this and/or upgrade the tires prior to delivery to the customer is not a business I would support in the future. A dealership knows about these issues, because they, and the manufacturer, have records of types & frequency of repairs for each model. This allows engineering to either redesign or respecify the requirement for parts bought for their units from their venders. Or, in some instances, hire their $500.00 / Hour corp. Attourney to limit their liability and still use the parts bought in volume under contract that the manufacturer is on the hook for.

The TPMS will keep you advised of tire pressure at all times therefore you will never be over or under inflated. A blowout is a sudden and catastrophic tire failure that the TPMS can not forewarn us of however it will warn of a loss of pressure giving us time to slow down or get off the road. Once that tire comes off the rim due to a undetected loss of pressure it will look and sound like a blowout. Many blowout are not blowouts at all but a un detected loss of tire pressure resulting in a tire failure. The TPMs is cheap insurance considering the damage that can be done bu a undetected loss of pressure.

Also agree the proper alignment is necessary.

I've posted about this in the past, but need to repeat myself (comes from age . . . ). Marathons aren't really bad tires, but they are SERIOUSLY wrong for a heavy trailer like a Montana. We had E rated ones on our old TT (10k gross I think) and they lasted well past their five year life expectancy. Were still on it when we traded up. They are used on thousands of horse, cargo and equipment trailers as well with little problem.

The issue with them on a Montana (or any other large 5th wheel) is they are almost always at least a year old by the time someone buys even a brand new trailer, and they are close to their rated limit even if brand new. ST tires are also not as conservatively rated as LT ones, so a rating for a three or even five year old LT will still be valid while one for the same age ST will not be anywhere near as published.

Bottom line, any E rated ST on a 15k+ gross trailer means you'd better be changing them out religiously at NOT MORE than five years.

[richfaa]

yes Walt. We had the Marathons on two previous TT's both CVW under 10K without a problem.

And better tires than the trail kings Montana is using now.
