Aging tire law???

[path1]

Maybe good for consumer??

Maryland House Bill 580 would require a tire dealer who sells a tire more than three years old to give the buyer a written statement that the tire is not new, and that many automobile manufacturers recommend that a tire should be replaced after six years, regardless of the remaining tread depth

Another example of the unfortunate fact that in this country anyone with a pet peeve can get a law passed (or at least proposed) in order to force their beliefs on everyone else.

The impact of 5 years of tire life in Arizona or Florida is drastically different than 5 years in New England or the Northwest, even just sitting in a warehouse. One size (no pun intended) does not fit all.

About as dumb as a law can be! A high percentage of vehicles sit 90+% of their ownership/life inside garages or even in A/C/climate controlled spaces. Many vehicles see well under 5,000 miles/yr. That's out of the sun, rain, salt, airborn polutants, etc and force them to buy new tires? For what reason? 40+ year old tires on street legal licensed historical or antique vehicles kept inside have NO tire rot or issues requiring replacement. Each case with tires needing replacing is very different and one bogus law doesn't relate to even half of reality.

The sun and heat compromises and rots tire compounds but most of North America averages only 25% or less of a 24 hour day with sun and then it's only on one side of the vehicle and it's tires. In the south and west, tire rot is many times the problem of the rest of North America and Maryland isn't even close to the high hot sun areas. How dumb can a legislature get?

Most people do not know about the date codes and even among those who do many do not know how to read them.. I know about the date codes and have read the "how to read them" instructions many times.

Still. if I need to read.. I need to look up how first.

Isn't there a date code on car tires? Truck and rv tires have one.

Yes there is, but, I bet the majority of folks don't know it.

just put new tires on my highlander. No, I didnt have them roll the new tires by me and decipher the codes. I would guess that 99.9% of the people don't. now if you were replacing one huge $$$ RV tire you might.

X-2, I never heard of a tire mfg date, until I owned a MH, we used to run tires "'till you can see the air inside them" as my Dad would say, as back then there was no tread depth requirement.
It was common practice back in the day, before steel belted radials, to run a tire until the cords showed. 😉

I would wager that even the 10 yr that Michelin and Cooper quote, are a "worse case" scenario.

Which would be very hot climates, out in the sun full time, etc.

If you live in a cooler climate, less sun farther north, etc., that tire probably will be good for quite a bit longer than 10 yrs. With inspection of course.

I am using truck tires here on the farm that are over 20 years old, looking good. Local use, not a lot of miles. Takes FOREVER to wear them out. Still look good.

These large, truck tires are very well built. Much more so than the cheap, China bomb trailer tires that get talked about.

actually both will work. the ninnies in the nanny state think they know best.

Please point me to any MFG site that states 6 Yrs. I know Michelin says 10 yrs another post states Cooper at 10 years but who (manf)is that says a tire should be replaced at 6 years.

My mistake, it came from the the car manufacturer that I work for, not the tire manufacturer.

It is in their dealer manuals.

Michelin states that the tire should be inspected at 5 years and each year up to 10 years at which time they recommend replacing the tire.

What manufacturer states that the tires should be replaced at 6 years?

Here's the quote from Michelins Service Life for RV/Motorhome Tires:

"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)."

Call me a cynic, but I'd have to see some references to believe the above, especially the first sentence. Who imposed/enforces that "can't be sold as new" restriction ???

Here's Cooper's take on tire life:

Cooper Tire is not aware of scientific or technical data that establishes or identifies a specific minimum or maximum service life for passenger and light truck tires. However, Cooper recognizes a consumer benefit from a more uniform, global industry-wide approach to the tire service life issue. Accordingly, Cooper recommends that all tires, including full-size spares, that are 10 or more years from their date of manufacture, be replaced with new tires. Tires 10 or more years old should be replaced even if the tires appear to be undamaged and have not reached their tread wear limits. Most tires will need replacement before 10 years due to service conditions. This may be necessary even if the tire has not yet reached its tread wear limits.

Dealer had new 21 month old RV tires "The warranty starts when the tires are put in service" --I asked him to call me when fresh stock came in. The concern is not the warranty but service life....

Found it interesting that his supplier would not shop dates on tires in the warehouse. Although once that started the older tires would die on the vine...

Good call.

The "old / new tire" thing is more prevalent with "unusual" sizes and types, eg: trailer tires.

Several years ago I was looking for replacement 15" ST tires for a small (19') TT I had at the time.

Figured Wally would be high volume. Tire guy rolls out a "new" GY Marathon that was over 3 years old.
Called him on that, he said it was his "only one in that size, and of course they would order new(er) tires".

So went over to a local tire shop that had been around for a long time. Told the owner/mgr I needed replacements for my current tires, which although they looked beautiful - I was aware of the 6-year thing - and mine were about 8-9 years old.

We chatted a bit - *HE* said - no, not 6 years, tires should be replaced after FIVE years.
No convincing req'd - he ordered me 4 new GY Marathons..:C

Called a day or two later - "your tires are in".
Took two of my wheels & tires to the shop to be swapped over.
Go back in a few hours, his employees have new tires mounted.

Just as an afterthought, I check the date codes.

Oops! What the hey? - Seventeen (17) months old..:(
Collar Mr. Five Years, he admits *HE* didn't bother to check!
(Hmmmm - that's over 1/5th of the lifespan gone by *his* experienced opinion!)

Politely told him - no way Jose, send 'em back - have your supplier find newer tires or re-mount my old ones, and I'll go elsewhere..:M

He gets on the phone to GY - or his supplier.
At the end of lengthy conversation, wait times, etc. - -
He says supplier claims GY only does production runs of STs in that size once a year. Supplier has nothing newer.

OK - so find me a different brand..:R
Bingo! Cooper ST tires about 5 weeks old.
And NO, he didn't offer any "deal" on the out of date tires.

(BTW - I don't run ST tires on my 5th wheel.)

IMO - Congrats to MD!
Lots of "regular folks" are clueless about date codes.
No big deal for high volume car sizes - but for anything else,.....

Buyer Beware!!..;)
