Tire Checking

Hey Guys & Gals,

I've read some ambiguous comments about this subject so I'm asking again. Just bought 2005 Tiffin Alegro Open Road 32 with only 10K miles on its original Michelin XRV tires. All tires have very minor sidewall checking or cracking. The dealer says they have 2 more years before this is really a cause for concern. Iv'e seen comments on these forums that do not agree. $$$ we are talking 5% of the purchase price but safety is more important.

What about Mfg? Is Toyo as good or what about other mfgs? Where does one get the best price in general?

Looking forward to hear from you.

Thanks
VAGABOND JIM

I would ignore anything the salesman says. Take a look at the date on the tire itself and see how old the tire is. It is widely recommended that MH tires be replaced from 5 to 7 years, depending on the history (if you know it) and whether there is any sidewall cracking. Since you said there is some checking and cracking, I would think it prudent to have them replaced. I realize that could be $3500 or more, but safety is paramount, IMHO.

I got my Country Coach in December last year and the first thing I did was to get a full set of tires. Joined the FMCA and saved about $1500 on a set of 295/80R22.5 mine had a build date of April 05 and I only had 17k on them, it is never the miles it is time

Vagabond Jim..... First of all, Welcome!! I know you'll find all you'll need on this forum.

I'll give a +1 to both nctox and 2stroker above. Your tires are at least 7 years old, possibly more depending on the codes you find. More to the point, on a used coach you have no idea of the use or abuse these tires have experienced. Overload, underinflate, UV,.... all these and more can render serious but invisible damage to tire rubber. Also, an odometer of only 10K miles on a 7 year-old coach would seem to indicate that these tires have spent a great deal of time sitting still, another factor not good for rubber longevity.

Add to these points the fact that you already have visible cracking and checking on these 7+ year-old tires, and IMHO, replacement becomes a no-brainer. Disregard the dealer's claims-- his priorities and objectives are far, far different from yours. Disregard the tread-- motorhome tires almost always age out long before they wear out.

Good Luck with the Allegro!!

Your tires could be up to 9 years old if the chassis is an 04. The tires on my 2008 were dated 0107. I replaced my Michelin's with Toyo's last year at Les Schwab's. I am very happy with the Toyo's and saved about $1300.

When I acquire a used mh (several over the past several years), I usually make new rubber all around a component of the negotiation. Always check the 4 digit code on each tire - there are posts in numerous places on line to help you find this code on your tires. I find that many installers seem to install this on the inside, so it is more of a challenge to find. We replace at 5-7 years, regardless of tread left. If you are already seeing weather checking and sidewall cracking, get rid of them. It just isn't worth it to risk a catastrophic failure at speed. If you are using your mh as lawn art, not such a big deal.

I have had the misfortune of a tire blowing out due to age. I had cosmetic damage as a result, but have heard of tire tread going all the way thru the floor of the Rv. I wouldn't take the chance.

I got an 08 rev , dealer put steer tires on said back ones were fine, for peace of mind I replaced them they were 5 years old. I might have kept them if I knew the history. Better for me to have new tires and peace of mind then blowout and tear up my coach and sit waiting for a service truck on the side of the road!

Check out this link: Michelin Sidewall Cracking Chart - iRV2.com RV Photo Gallery It will give you something to compare with the tires.

Just replaced my XRVs with 10 years of excellent service, BUT, I was original owner and took "excellent" care of them. Without knowing the history on a set of tires, I would replace at 5 to 7 for sure. Remember that the letter "RV" in a tire name mean the tire was specifically designed for RV use. Tires without the designation are basically truck tires that are of course, also usable on an RV. Good Luck

There are only 2 tires that are marketed as RV specific. The Michelin XRV and the Goodyear G670. Both tires have had issues over their history. The XRV has had more than its share of "zipper" failures. The G670 is prone to "river" wear when used on the steer axle. All tires on heavy vehicles live in a hostile environment. Running under inflated and the occasional curb hit or big pothole will shorten their life and you can't tell any of that with a visual inspection. Regardless of your best efforts, an accumulation of hidden damage can lead to a tire failure before any specific number of years have passed.

Good call. It is not a question of "If you will replace the tires" it is "When you will replace the tires". I just had our seven year old MH tires replaced. While they could have gone a bit longer I felt that there was no reason to wait when life and property are at stake.
