When to purchase new tires

[Brians-THOR]

Hi everyone,
We purchased new tires Aug 2019, Hancook E class . Our small motorhome is a 2012 Chateau 19G.
We’ve put 28,000 miles on them since the purchase we live in northern Pa, and we spend 3 months in FL.
No signs of wear and no checking.
My question is, is age the determining factor vs signs of wear to make a new purchase?
Thanks In advance!

Blow outs are very expensive even without damage. One tire on dually blew then shreaded the black water tank valve and ruined the other tire. Two tires in the dark from AAA was over $1,000. The other four cost another $1,000. Repair was $800. At six years get nervous, at seven years ask a tire guy.

Doesn’t most of tire aging come from UV?

Is 51% most? Many other environmental factors add to "aging"/dry-rotting. As mentioned above, nothing is a substitute for inspections.

The five to seven year point is do to steel belted tires. If and only if a tire is penetrated by an object to the steel belt, but not through it as to cause a flat, the steel belt begins to rust. This releases the rubber to steel bond. Five years later...BOOM. So if the tire is not penetrated, your good to go. So most will not have this happen. So it is your choice to replace or not to. No steel belt, no problem. Tires do age out though. At seven years they should be dismounted and inspected. At that point I purchase new ones.

Date code on tire is older than date of purchase of a motor home.
Me, I live in Fla and do a trip to CA every year and misc trips in the SE. 11,000miles last year. On my way to Daytona I heard an unusual noose. Right rear outside dusl had a small. Bulge had it replaced. Going tomorrow to have the other 5 replaced. Same tire same truck tire shop. $1500-1800 is worth the peace of mind vs a roadside catastrophe. IMHO

RE: TIRE REPLACEMENT ON RV.
When in storage, I use tire covers from Minards, and have [rubber] tiles between the tires and ground. Both help the longevity of the tires. Always see that your tires are properly inflated. My tires are rotated and balanced every 5000 miles [important]. The Thor Manual will have the proper rotation pattern. An alignment is done every 10,000 miles unless the RV pulls or shows tire wear. I would consider pending tire replacement at 8-10 yrs, Checking, or tread depth of 3-4mm.
As a side: Tires cost a lot. So can fuel. Don't feel like you shouldn't have an RV just because those might be a concern with your family budget. RVing isn't just for the wealthy.

I just replaced my 9yo Michelins.
Found, what I believe is a good buy and decision.
Toyo commercial Celsius Cargo. 225/75R16C
(Don't get confused, they also make 225/75R16E which do not have as much load capacity)
6 tires plus install, balance, and the damn 7% sales tax= $1178 out the door.
Only time will tell whether that's good, though.

I agree that it varies depending on use. However, I changed my Palazzo tires at 6 years even though the tread was fine and I saw no cracking. Tires oxidize and the risk of a blowout could be life threatening. I'll take the cost to mitigate the risk. We used a local tire shop but discovered they could not balance the tires and we had vibration. We drove to a larger town that had a truck tire place, they balanced the tires and we've been fine since then.

I was thinking about the tires on my mega C last fall. The tires looked good. Plenty of tread. Sidewalls looked good. Two more campouts to go in the season and then I planned to replace them just because it was on a 2017 chassis and that meant the tires were ~7 years old. Twenty miles from the campground the driver side inside rear tire blew. Sure wish I had not waited. The repairs to the motorhome from the blowout damage was double the cost of the new tires.

You can never know for sure. A year ago, I replaced a set of six year old Hankooks that had 30,000 miles. While on a trip, I felt severe vibration in the steering. The left front tire had a sidewall bulge the size of half of a grapefruit. It could have easily been a blowout! I bought one replacement tire to get home and then replaced all six.

There were no visible signs of damage and I could not recall hitting anything that would have damaged the sidewall. In nearly 60 years of driving, it was a first!

Similar with our coach, bulge on right rear outside. replace it and when we got home replaced other 5.
