Hi guys, I found a flat on my tag axel after winter storage and it has a lot of cracks showing on the bulge , still a fair amount of tread but I think these tires need to go away. If this dot number is what I think it is they are relics !
DOT N34F 2N34400 Toyo ? Anyone know what these numbers mean ? Thanks Don

Don,
Don't know what the numbers you have mean. If you are looking to determine the tire's age you need the four digit number like in my photo. In my case the numbers are 1215. Tire was manufactured in the 12th week of 2015.
The numbers you supplied look like the first part of the DOT code. Unfortunately, current regs only require the complete DOT code to be stamped on one side of the tire, so it's possible that the date portion of the code (the last 4 digits in Steve's attached photo) is on the inside wall (ugh). A lot of installers (and buyers) don't know this when they mount the tire.

How flat?
If the rim was over half way to the floor, first thing I'd do is drill a hole in the sidewall to mark that tire as ruined.
When the sidewall flexes that much, the structure of the tire is damaged. Seen it several times.
Replace it & be done with it. Dealing with the damage caused by a tire that fails at speed isn't pretty.
I suspect everyone has an opinion regarding brand of tires. I will only run Michelin. Several years ago I had both almost new Toyo tires blow on the front. One blew at 70 MPH. The thread separated on both and Toyo would not honor their warranty because it did not save the razor sharp bodies. Just my opinion.

It was just about empty , and with the cracks and number 4400 , it's done !

I guess it's time to move the hankooks from the front to the tag and get some decent 24.5 steering tires , the numbers tell me that these 4400 are 17 years old , wow thanks for the feed back ! Don

Be sure you get at least a load range H steer tire. A lot of places will say" G is fine. All the semi's run G" Their front axle weight is a lot less than a fully loaded Newell. We have been happy with the Yokhama tires we got last year for steer & tag. Also request that they give you new tires with recent DOT dates.
