This would be why you replace tires every 7 years.

My Dynaquest chassis was built in 2008 with 2008 date code Michelin tires so before we leave for the Dynamax ralley & 1O00 + miles I thought I better replace them. Im glad I did. Just posting this to reinforce the idea of replacing tires before they give an issue.

Good idea, I believe anything over 5-6 years is pushing your luck.

X2 ours are 2013 date stamp. Getting them replaced this year before our long trip even though they “look” ok. Not worth the risk.

I think the “official” is 6 years fro date stamp but I could be mistaken.

Might check out what the manufacturer recommends: https://www.michelintruck.com/assets...fe_RV_Tires.pd


Other tire brands may have different standards. My DX3 came with Michelin's .

Michelin says 7 years replacement interval, I was hoping that since they were covered & only had 17000 miles they would be better. The worst one in the photo was an inside rear tire! couldnt see the sidewall cracking by looking at it. I read good reviews about the Toyo tire & your not paying for the name.

Used Michelins on all my RV's till a blowout with a 6 year old tire that was very low miles. Went to Cooper, very happy with the results over two years now, still look new, nice ride and a lot less expensive than Michelins. Got them at Discount Tire and with the tire warranty they have no worries.

I had to replace my tires at 3.5 years, I live in Southern Nevada. The heat and low humidity take a toll on tires.

I replaced my tires on the previous class "C" after 5 years. There was still plenty of tread left but, just like the OP, the sidewalls were beginning to "rot". They weren't too bad but why take a chance when everything I hold dear in the world is traveling in that RV.

20+ years ago my trusted motorcycle shop manager talked me into replacing my back tire with a Toyo. Never heard that name before and I was very reluctant but the price swayed me.

After getting acclimated to a different profile I was happy and would not hesitate to buy Toyos today.

every 5 years

I put about 7 thousand miles on my 5er a year , I change my trailer king tires every 3 years. Seems a small price to pay for peace of mind.

Hard to get tires repaired over 5 yrs old

[Nurek]

There is this old-timer that I see in the fall at my CG and he spends 1 month.

We got to talking about his rig. He was saying his TT is over 30 years old and doesn't owe him anything.

I was checking out his tires and noticed the build date was in 1995 sometime. They look pretty brittle. All 4.

I said to him that he should replace his tires pretty soon. His reply was "I only drive up here and back home in a year and can't be bothered".

It's a 1000km round trip through mountain/canyon passes and gains from sea level to over 1230m (4000+") and back down.

Traveling public, this is what are sharing the road with.



Funny thing... this guy is a retired trucker with over 1 million miles.

I am glad you got it before it got you!! I have always put Michelins on everything I own. I just put Goodyear RV tires on my Dynaquest because I couldnt get Michelins in the size and load rating I needed. So far so good, but It has only been 9 months and 4000 miles ago. They do ride nice though.

Want a real eye-opener? Go stroll through a truck stop parking lot and look at their trailer tires. Especially the "inter-modal" trailers that are transported both on rail cars and highways. You'll see tires that look like they're 20 years old with weather checking, channel cracking, and you wonder how they hold air. For some reason you don't see them blowing out all that often considering the number of miles they have put on them.

Whenever I'm driving on the interstate and hear the "whup, whup, whup" from tires on a truck alongside me I immediately try to get far, far, away. Either way ahead or way behind.

If you add cover`s on the tires when not rolling, you can keepe the tire`s with no wall crack for a very long time.
(More then 10 years)
What make the tire crack is if it is not rolling often and if it is burn by the sun UV.

[bend302]

Just changed out four 7 year old Goodyears that looked like new. Hurts, but the other two were replaced two years ago when one of the duals went soft and everything heated up and blew the inside tire.

So, yeah, 7 years is the practical limit.

Go to the "RV.net" forum. Probably the largest forum about all RV's anywhere. It is not unusual for Michelin's to have that cracking at an even newer age. Seems to be unique to them based on tires your age or even newer.
