Michelin AT2 tire evaluation at precisely 6 years old:

Purchased 4 Michelin LTX AT2 (245/75/R16, E-LR) 6 years old in 2-weeks:

-very nice riding tire, with 1300 LB pop-up camper during spring/summer;
-required almost no weight supplements to balance all 4 (remarkable!);
-we stored truck outside for 1st time since 2005, and I tried these tires in winter conditions: absolutely horrific in snow, ice and slush (of course; they are not winter compounded rubber!);
-very quiet sound on bare pavement;
-hold the road well in rains (during hellacious flooding in/near Elizabeth City area of North Carolina);
-front passenger tire showing MARKED crazing of entire sidewall since March, after only 26,000 KMS (16,155 miles) of use.

There it is. Will replace all 4 (with unknown brand), and trash the AT2s in May, before camper gets loaded. Currently, only driving truck to village 3 KMS away for groceries, till new tires installed.

*these tires were bought to replace 3 year old BFG TA/Ko LR-E tires that were catastrophically cracked (all 4 of them) between tread blocks and side-walls after only ~23,000 KMS (14,290 miles). Truck parked in the shade 91% of its life-span (45% of that 91% in indoor storage; the 9% traveling) with these tires mounted (ie. no incoming shortwave (UV-A or UV-B radiation; very little ground ozone up in the mountains here).
  • Sounds to me you've had decent service out of the Michelins based on your write-up. 6 years in cold winters. Yes you may not have many miles on them but time take its toll on rubber exposed to the elements. That's why most motorhome tires are replaced due to age versus mileage.
  • Wild Toad:

    Yes. Agree completely. 6 years is, in my estimation, a "long life", notwithstanding mileage. Rubber ages, whether driving on it nearly continuously or occasional 6 years of use...
  • Six years without a significant failure is very good for a trailer tire. I'd be thrilled to get six years. I replace all of mine at 4-5 years without fail.

    Silversand is talking about his truck tires not trailer tires. You are in the TC forum.
  • Was at my tire store last week and a Tiffin motorhome came. He had issues with all 6 Michelin tires and extreme sidewall cracking. The worst that Ive ever seen. Told me they were 4 years old and brought the RV in because he needed to go to a Michelin authorized center. I think Michelin was going to help him out but they wanted photos sent to them from the tire center before they could approve replacement. This guy told me he keeps the RV parked mostly in the shade.

    I had the same issue in the past with only 2 yr old tires.
  • I have notice this trend. Tires used to last longer before the sidewalls went to hell. Modern compounds? I had to replace the original tires on my F350 after only 80,000 miles and 12 years, just because the sidewalls looked horrible. Tread was just fine, could have gone another 40,000 easy. The Goodyear Marathon trailer tires seem to last longer, and they make a big deal about the extra lampblack or something in the sidewall. Why don't they make other RV tires with the same ideas? So they can sell us more every 5 years I suppose....

    The older tires were good.


    Can you elaborate?

    Any proof (SAE studies) that Michelin is using different rubber compound after x year, leading to early side-wall cracking ?

    What LR-E tires (and purchase date) have truck camper owners had overwhelming success with (ie. not early rubber cracking/crazing nor blowout/belt separation) ?
