interesting video exposes the problem with a few major retailers who were caught selling very old tires to consumers. Watch the video and you will understand why it is important to check the manufacturing dates on all tires that you purchase.

It was brought to my attention that some states inspect motor homes for older tires. I was looking at my motor home's front tires, that appear to be in new condition are greater than 10 years old that is the maximum age. With a closer inspection there is evidence of fine hair line cracking in the walls and therefore they have to be replaced, even though they look new.
LOl,The two front tires on my old 8N tractor were put on in 1954.
I'm still running some 6 ply jeep tires on my 54 NAA Ford tractor I put on in the 70's and they were old then!
Are they cracked? of course they are but they are good enough for shredding in mesquite pastures!
Guys, Here is an article that I wrote several years ago and have updated to current DOT regulations. It mostly applies to motorcycle tires, but does have application to any tire used on the street. As for farm equipment, if it holds air use it, in my opinion.

A directly related matter:
In 2006 we purchased a new boat and trailer. The trailer is a single axle unit and is equipped with a spare tire, so 3 tires altogether. Within the first 2 years (and not very many miles) all 3 tires failed. It turned out that the tires were fine. It was the stems that failed. Apparently when the wheels were assembled old stems that had been on the shelf for a long time were used.
I can attest to the fact that when a stem lets go at speed it's no different than a tire letting go. Either way is an attention getter!
Moral of the story: If you're gonna take the time to check the age of your tires, take a good look at the stems too. They won't be marked with a date like the tires, so wiggle them and look for cracks. If it's gonna fail, much better to do so in your driveway than on the road.
Big Rigs are very fussy with front tires as a result you rarely see a large transport with a front flat. It is common to see cold caps scattered all over the place on the highways.
I have survived 2 catastrophic failures on Motorcycles (one of them on the front tire) both happened at speeds in excess of 65 MPH and neither resulted in a crash. Both were due to "old" tires. When they asked me how I brought the bike to a stop I said I didn't touch the brakes! both were very wild rides< I always check the dates now drive safe!
2 years ago I traded my 29 Chev coupe (driven often) that had S-3 tires all around. I'm told that was the "rationed" tires during WW II.
Jack, that may be true that your tractor has 61 year old tires that still hold air, but then again, they're not buzzing down the highway at 65 mph either. I doubt they'd make it 20 miles at that speed! Just sayin.
