Nope, not since 1978 when I stopped selling race tires.

Just bought 4 Sailuns from my local tire shop. Oldest tire was 1618, newest 2118.
Getting new, new tires is why I use my local guy.

For grins I did it again - no quotes - tire life = About 17,400 results (0.31 seconds) The search line read "tire life site:irv2.com" without the quotes.

At the FMCA gathering in Shawnee ok, a seminar was given on the DOT rating of tires. Basically they are good for about 6 or seven years from DOT date. I bought 6 new ones at Discount Tire using the DOT date for this month and year. Mine were 7 years old this year and are from the date of the R V.
FMCA has information on tires on their website.
I would suggest checking tires for cracks on sidewall and date and get new ones if over 6 years old

Happens all the time. I have a friend who had 11 year old tires that had 4500 miles on them.

You should worry.

The general rule, for safety and to prevent damage to your own RV, is five years for trailers and seven years for motorized vehicles. One tire just throwing it's tread off cost me more than a new set of tires cost...

RUBBER MANUFACTURERS ASSOCIATION says, "Service Life is Not Determined by Chronological Age" and "RMA is not aware of reliable and accurate scientific or technical data that establishes a specific minimum or maximum service life for passenger and light truck tires."
In other words, they don't believe in removing a tire strictly due to age. The whole article is below.

They are responding to the question of tire life on normal passenger vehicles, not RV application.
RMA does not have a clue IMO about RV tire usage.
But if you want to drive till the tread is worn out go at it. Just don't complain when you have a failure and have $$$$ worth of trailer damage.

Embarrassed to say I overlooked the rear inside dual of my class A (out of sight-out of mind) and suffered a blow-out recently and discovered the make year was 04. Well beyond its time. Suffered minimal damage.
Everyone should have a list of tires on any RV with the mfg dates. I sure learned my lesson.
Change tires on your terms not due to a catastrophe.

YES, they age out. A tire can fail internally from belt failure or other failures due to age. Sure the sun and environmental conditions will cause most of your issues but some can't even be seen. I replace my trailer tires every 5 (maybe 6 if they check to be ok and I have kept them indoors) (pop up stays in the garage) years from the installed date. Last year I replaced my pop up tires that looked brand new, totally due to age. I just want to do anything I can to prevent a failure and be on the side of the road. I think most MH owners adhere to the same tire age rule as well.

Here's what I have:
Quote:
Michelin Technical Bulletin
Service Life for RV/Motorhome Tires
The following recommendation applies to RV/Motorhome tires. Tires are composed of various types of material and rubber compounds, having performance properties essential to the proper functioning of the tire itself. These component properties evolve over time. For each tire, this evolution depends upon many factors such as weather, storage conditions, and conditions of use (load, speed, inflation pressure, maintenance, etc.) to which the tire is subjected throughout its life. This service-related evolution varies widely so that accurately predicting the serviceable life of any specific tire in advance is not possible.
That is why, in addition to regular inspections and inflation pressure maintenance by consumers, it is recommended to have RV/Motorhome tires, including spare tires, inspected regularly by a qualified tire specialist, such as a tire dealer, who will assess the tire’s suitability for continued service. Tires that have been in use for 5 years or more should continue to be inspected by a specialist at least annually.
Consumers are strongly encouraged to be aware not only of their tires’ visual condition and inflation pressure, but also of any change in dynamic performance such as increased air loss, noise or vibration, which could be an indication that the tires need to be removed from service to prevent tire failure.
It is impossible to predict when tires should be replaced based on their calendar age alone. However, the older a tire the greater the chance that it will need to be replaced due to the service-related evolution or other conditions found upon inspection or detected during use.
While most tires will need replacement before they achieve 10 years, it is recommended that any tires in service 10 years or more from the date of manufacture, including spare tires, be replaced with new tires as a simple precaution even if such tires appear serviceable and even if they have not reached the legal wear limit.
For tires that were on an original equipment vehicle (i.e., acquired by the consumer on a new vehicle), follow the vehicle manufacturer’s tire replacement recommendations, when specified (but not to exceed 10 years).
The date when a tire was manufactured is located on the sidewall of each tire. Consumers should locate the Department of Transportation or DOT code on the tire that begins with DOT and ends with the week and year of manufacture. For example, a DOT code ending with “0304” indicates a tire made in the 3rd week (Jan) of 2004.

Toyo RV Safety
Tire Damage and Aging (Non-Commercial Use)
Vehicle operating conditions and tire maintenance practices vary widely. Tires should be routinely checked for damage or signs of fatigue or aging. This should be done at scheduled vehicle maintenance intervals and preferably on a lift so that the tires can be thoroughly inspected by a tire professional.
Tire longevity is extremely dependent on factors such as air pressure maintenance. It is recommended that tires be thoroughly examined by a tire professional after reaching five years of service. Even tires with serviceable tread remaining may require replacement prior to wearing out. Tires which have reached a remaining tread depth of 4/32nd should be replaced.
The age of your tire can be determined by reading the sidewall. Every tire has a 10 or 11 digit DOT (Department of Transportation) identifying number on one sidewall.
The last 3 or 4 digits are the most important to you. Older tires have 3 digits, the first two identifying the week of manufacture and the third digit the year when the tire was made. Tires made between 1990 and 1999 may have a triangle alongside the numbers. As from January 2000 4 digits are used, the first two give the week of manufacture and the last two digits tell the year the tire was made.
