Tires. How old is to old

[mookie6]

My tires on the wini 34ft are now at 7 years. Never kept them covered and always outside. Any Idea when to replace them. Thanks

But your tire blew out at 1 year old. So it sounds like you should replace your tires every 363 days in that case.

My point is the folks that have had blow outs are not quite as apt to extend the time between tire replacement, as those who haven't. I really thank you for your very astute observation.

You do not understand

Sunlight exposure does not matter - 7 year life

under inflation does not matter - 7 year life

Over loaded MH does not matter - 7 year life

High southern heat when driving does not matter - 7 year life

etc. etc. - 7 year life

Respectfully, I disagree with you. He understands perfectly that with reasonable care which includes preventing moisture from coming up around the tires from the ground, storage indoors, close inspection for cracking, proper inflation, not scuffing the sidewalls on turns, not left stored in standing water, kept out of direct sunlight, etc, that their is realistic potential for safely running your tires beyond the 6-7 year time frame. The longer this period is the more intense your tire maintenance and observation should become.
Even with all of this attention the day to change your tires out will inevitably arrive.

Anyone know what type of $'s you're talking in having them professionally inspected?

I certainly understand what you are saying. This is how it was explained on a tire thread a while back.

Tires are like a bowl of spaghetti.... the thread and belts are the noodles and the rubber and emollients inside are like the gravy (sauce). When the tires are heated the gravy mixes well with the noodles and everything is copacetic. Tires sitting will kill them.

I suggest some materials engineering courses instead of good old boy gravy stories

abused tires will need to be replaced less than 7 years

well treated tires will last longer than 7 years

temps, stresses, UV exposure, abuse, etc will all affect tire life

Being Italian, I kinda liked my tire reference story :B

Tires sitting in a garage on boards, etc. is not good tire maintenance.

And I agree with you and the poster that says having them inspected professionally is the way to go.

Safe travels,
MM.

My last set of Michelins I replaced after 10 years! I don't get tire advice from the RV.Net tire Inspectors. I had my tires broken down off the rim every year after 5 years and inspected inside and out by a certified tire expert at my tire shop! It gives me peace of mind and I know exactly what I'm driving on!

Best answer!

EXACTLY

If inspection by tire experts say the tires are kaput at 5 years you need to replace them at 5 years


If inspection by tire experts say the tires are kaput at 9 years you need to replace them at 9 years

Simplistically repeating 7 years will either waste money OR PUT YOU AT RISK OF A BLOW OUT

I'll bet this breaks down to who has had a blowout and who hasn't. We had a front tire blow out on 1 year old GY's, did thousands of dollars worth of damage, but I was able to get it safely to the side of the road. I was lucky there was no one right beside me. So for us, it's 7 year max and never again a GY tire. By the way after a fight with GY they finally paid for everything. Also as Mr Mark said it is more important to drive on the tires regularly and keep them properly inflated than most anything else.

I just replaced the tires on my coach that were 10 years old. They still looked fine and after they were off and inspected they still looked ok.
If I had taken them off at 7 years they would have gave me a used tire price on them ( a little more than casing price) and it would have taken some of the bite out of the cost.Tire shops cannot sell them after they are 10 years old. There are farm trucks and other equipment that can use them at 7 years old.

I was pushing it with the 10 year old tires and will trade them back in 7 years. This is what my dealer told me, they all may not be the same.

What a lot of people don't understand is a tier ages from the time it comes out of the mold. They will go bad siting in the warehouse.
If you dig around on the Michelin web site it will tell you the tiers need to be dismounted to be properly inspected.
