9 year old tires
I know this has been discussed many times I am sure, but as a newbie with our first coach and I just saw that our 2008 CC Inspire has (1207) tires...YIKES! The coach has only 17,600 miles on it and it was stored indoors most of it's life. The tires have fabulous tread left and there is no sign of any sidewall deterioration (sun damage, etc). I just read an article saying RV tires are designed to last 9-10 years max...UGH!!! These are Goodyear 670's and when I drove it 3 hours home it seemed to be perfect...no shakes, pulling, thumping, or anything that would worry me. Was told they had been replaced about 4 years ago, never checked the dates on the tires....doh...
I have no issues with buying new tires ($5-6k most likely) if that is what needs to be done...ugh.
Advice please?

You will have to decide for yourself, but with inside storage and perfect appearance and performance, I would extend the nine or ten years by at least 50% from my experience. If you are more concerned, you may wish to replace your steering tires.

If you have any apprehension as to their remianing you could have them dismounted and inspected by a reputable tire shop.

I had Goodyear 670's on my 2002 coach when I bought it in 2008.
The front tires had a bad wear problem so after getting alignment checked I changed out to Bridgestone.
The rear tires looked good and I continued to run them until 2011, they were right at 10 years when I changed them out. I inspected each tire as it was pulled off and found no problems with any of them but 10 years is a stretch, especially the fronts.
If money isn't a problem I'd change them.

For one more year.....it's only my worst fears that would haunt me for that entire time.
Thankfully, your risk, sir, not mine!

We have the same situation with our tires. Want to replace them ASAP but the DW's recuperation/medical bills will have to come first.
Ours are all Michelin's and there aren't even any "dry" looking area's.

I changed my Michelin XZA3's at 8 years. They looked good with no signs of cracking. So good in fact, the dealer gave me $110 each for them to use as trailer tires.
If you loose one, aside from the danger factor, the body damage alone can be secondary to the cost of new tires.
I fell a whole lot better going down the road on new boots.
BTW, out the door, installed with balancing beads and tax was under $500 per tire for new, 1 month old XZA3+.

I recently bit the bullet (to mix metaphors) and changed out the tires on my MH. Mine were all looking good, at least all the road tires. Those six showed no signs of cracking or wear, but were old. The spare from the storage bay was the worst. It did look a bit weathered and cracked.
Of course these were the tires I got on the MH, a 1988 Fleetwood Southwind, with 100k miles. Because of this, and that they were an odd mix of different brands, I feel better since I replaced them.
However, I should note two things. The tire shop could find no mechanical faults with any of the road tires. That is one thing.
The other is that they did not look hard, because they said they are not allowed to re-install any tire over 10 years old. Mine are 19.5 x 8, and they are considered a commercial truck tire. I was told that DOT rules say they cannot repair, or re-install a tire over 10 years.
My tire shop said it has to do with the tire compound, and not just their appearance. The rubber itself ages, so they said. Of course, they also had the interest in selling me tires.
Mine were so old that they could not find any date codes on them. That means they could have been far older than the 10 years.
I do store inside, and am sure these I installed are going to be on the MH for most likely their full 10, maybe more, since I know exactly what abuse I will put them thru, and currently are still just camping a couple times a summer in this unit. Once I use it more, I will adjust accordingly.

We replaced ours at 8 years. Had some cracks showing. New tires was a great piece of mind and not worth putting off. TPMS was added right after new tires.

Ozone is as destructive to tires as anything and Ozone is not shielded by being inside or under covers.
RV usage of a tire is the worse case because the tires are used so little. The tire composition has emoluments that work to protect the tire when used. RVs sit idle most of the time and that emolument protect is not available.
Be wary of statements about tires lasting 9 years. For example Michelin states so but only if after the fifth year, the tires are dismounted and checked inside every year. At the cost of removal, dismounting, mounting and installation, the cost savings go right out the window.
I bought a 7 year old motorhome 13 years ago. The spare had never been dropped from the mounting place. Hidden from the sun, that spare was unusable as it had deteriorated. The reason I wanted to use the spare that one of the tag axle tires, that looked just perfect, disintegrated.
A tread separation on a trailer tire cost $6000 to repair. Pusing tire life just doesn't make sense compared ti what can happen.

You are in the same boat I was in last January and I feel your pain. It seems a shame to get rid of perfectly good (looking) tires especially considering how much new tires cost. I wanted to get this behind me before I retire so I replaced my G670s with Toyo M144s and got $400 for the 7 GYs (with 15k miles). I'm sure you already know that when one of these tires comes apart, it makes a helluva mess. If it helps with the decision, you should be able to get 6 tires for just over $3k OTD.

We replaced our Michelins when we bought the MH. They were five years old, 50,000 miles on the tires, with extensive cracking on the side walls. The tread looked good.
I replaced them with BF Goodrich Commercial T/A tires. These have been a major disappointment, four of the six have failed between 25,000 and 30,000 miles due to belt separation.
It's a crap shoot. I don't think anyone makes a decent tire anymore.

9 year old tires
I say replace them now. While you are not in a rush due to a failure or on a trip.
My experience:
We bought a coach with ~9 year old Goodyear 670's. They looked great. So figured I would run them a bit longer. A couple trips and blew one on the freeway. Luckily no damage to the coach, no accident, personal injury, etc. We had a mounted spare so ERS came and swapped it on and came on home. Bought a new set of Michelins the next week.
