Goodyear F1 Production Schedule

I just checked my tires installed last year and the date code is 23 of 04!! They are already 5 years old. This seems like a pretty big issue if the newest run is truly early 2006. I know that as a supplier to Ford we have to produce service parts for 12 years but I do not know if that is true of a tire supplier. Does anyone know for sure if 2009 F1's can be found? Thanks.

While I was at the Discount Tire at 43rd Ave and Bell Rd in Phoenix buying tires for my Range Rover Sport, I got into a discussion with the manager, Kinny Denton, about the status of Goodyear F1s for the GT. Kinny called their special order rep at Goodyear’s corporate headquarters. The rep said they have an inventory of both front and rear tires in their Tennessee warehouse, but that she did not have access to the manufacturing dates.

She checked Goodyear's schedule and reported that new production is scheduled for August 31, 2009 for the front tires (product code 31767), and April 5, 2010 for the rear tires (product code 31768). Tires received from the Goodyear warehouse after those dates may or may not be new production, depending on how quickly they sell the existing inventory. The tires are shipped out of Goodyear’s warehouse strictly on a first in, first out basis (they won’t pull a later production tire even if requested).

To try to get an idea of production dates on tires currently in the Goodyear warehouse, Kinny called a Discount Tire dealer in North Carolina that showed four front tires (no rears) in their inventory. The NC dealer laid eyes on the tires while Kinney was talking to him, and reported a production date of 45-08 (the 45th week of 2008). The NC store’s records showed that they received those tires in December 2008, so they were pretty fresh when they showed up at Discount. Applying Goodyear’s “first in first out” policy indicates that all the front tires currently in Goodyear’s Tennessee warehouse were manufactured no later than 45-08.

We tried to determine the same thing for the rear tires, but were less successful. As of today there were five rear tires in the entire Discount Tire system; all are in warehouses and not at dealers where it would be easier to read the date code. Kinny called the Phoenix warehouse where two of those five tires are. The warehouse guy couldn’t get to them because they were “buried” in the warehouse, but was able to verify that they received the tires from Goodyear in October 2008. So, it was not possible (yet) to estimate what the manufacture dates might be on the rear tires still in the Goodyear warehouse. The guy at the Phoenix Discount Tire warehouse is going to try get to the tires in the next few days to read the date codes, and he promised to call back.

Regarding the "new" F1 tires with old production dates that Forum members have found, Kinny speculated that some companies like Tire Rack may have bought in volume and then didn’t sell them as quickly as anticipated. It appears that if tires are ordered by a dealer and they are shipped from Goodyear’s Tennessee warehouse, at least the front tires will be less than a year old.

I'm sure we'll see these old production tires surfacing for years to come - watch the John Stossel video Bony posted, and re-posted by Sam earlier in this thread http://abcnews.go.com/Video/playerIndex?id=4826897 The lesson for all of us is to check the date code on every tire you put on any car- regardless of the brand or where you bought them!

Thank you for all the effort to help pin this down. It is good to know there are newer tires to be had. Mine were purchased from and installed by my Ford Dealer which doesa not instill alot of confidence that I can count on them for help.

Be VERY cautious when buying "new" Goodyear F1 REAR tires

This morning I had a lengthy follow up call from Kinny Denton at Discount Tire (see post #41). In my opinion there's a problem that will only become worse in the future regarding old production Goodyear F1 rear tires, exacerbated by the GT being the only market for them.

The two rear F1's currently in the Phoenix Discount Tire warehouse were manufactured in 2004. They were received from Goodyear in early 2008, not in October 08 as I previously posted. This squares with the 3605 (36th week of 2005, or early Sept 05) production date on the tires bought from Discount for my car on 8-22-08. [Note: the Phoenix Discount Tire warehouse is primarily for mail order and not for suppling local stores; my tires were obtained through Purcell, Discount's local wholesaler, which explains why the 2004 tires are still in the Discount warehouse.]

Unless someone has different information, it appears that as of about a year ago the tires coming out of the Goodyear Tennessee warehouse were 2005's. Does anyone have any rear F1's newer than 2005 production?? My guess is no, but I hope I'm wrong.

The question is, what will Goodyear do with their five year old rear tires after the new production run in April 2010 (assuming that they actually do the run)? I suspect the mostly likely scenario is that they will discount the tires to dealers, and the old tires will wind up floating around in the system forever - waiting (along with unsold 2004 production now in dealer stock) for an unsuspecting GT owner to buy them.

What is "old" for a tire is a murky area. Kinny said that he personally does not want to install a tire more than four years old on any car, and will not install a tire more than six years old. Discount Tire's company policy is that they will not TOUCH a tire more than ten years old if you bring it in - they won't even put air in it. There is currently no industry consensus or regulation regarding the maximum age that a tire should be taken out of service (not the time since installed, but the time since manufacture). Some tire manufacturers believe 10 years is the max, but many car manufacturers believe tires should be taken off the car six years after the tire mfg date.

Even the warranty adds some interesting twists. Most passenger car tires now have a six year warranty, beginning on the installation date. But as Kinny pointed out, if you keep the tire in service beyond the manufacturer's warranty and you have a catastrophic failure, you may have a much more difficult time making a legal claim against the tire manufacturer. Now here's something that'll make you think twice about putting those 2004 F1's on your GT today: they're already five years old, and the warranty will last until they're 11 years old. But even though it's perfectly legal to keep driving on them, a company like Discount won't even put air in them during the last year of warranty because they're over 10 years old!

Regarding non-passenger car tires, Kinny said that trailer and RV tire warranties are typically three years max - simply because they are not used regularly. Lack of regular "exercise" will prematurely age any tire. For those trailering your GT to the Rally, check your trailer tire date codes now.

Every current owner should be aware of his tire date codes, and a check of the manufacturing date should become part of every PPI. Tire age, particularly the rears, is going to become more of an issue as the GT fleet ages, regardless of the tire brand. An informed GT owner will pass up the older production "new" tires (possibly offered at bargain prices), but the inevitable downside is that those old tires will just sit on the shelf even longer before being sold to another unsuspecting buyer.

It's too bad the new 2010 Ford Shelby Mustang doesn't use our rear tires, rather than the Goodyear F1 Supercar 285/25R19's specified for it. It would have been nice if they were the same to turn over the stockpiled inventory.

The major key to the "shelf life" of a tire is in how and where it is stored.

If the tires for the GT come directly from the Goodyear distribution system, guaranteed they have been stored in a heated facility with correct temperature controls and ventilation systems. And have not been allowed to be compromised with excessive heat (or cold) and no direct sunlight. All this is done to keep the tires as fresh as possible.

If the tires come from a source such as Tire Rack/Discount Tire etc, they will be kept in distribution facilities just like the manufacturer's use.

The biggest area of concern is when the tires leave the distribution system and end up at the local dealer. Who generally do not have "factory type" storage systems. These are the tires that are on a rack, pushed in and out everyday, have been exposed to sunlight etc. This is where you need to be really careful. I suggest that you inspect the tires yourself prior to having them installed on your GT. If they are not fresh looking, still a bit tacky to the feel, and your fingernail doesn't easily press into the tread block--don't have them installed on your GT. Have them order another set for you.

This information is meant to give you a guideline, and comes from contacts that I have in the tire world.

I personally not too concerned over the production dates on the GT tires. While the shelf life is not meant for an indefinite period of time, factory fresh tires are available from Goodyear.

And the really good news is they will be producing more in the near future.

I just purchased some Original Equipment Goodyear F1 tires from the tirerack. The fronts were manufactured in 08 and the rears in 06.

I've made many passes at the Texas Mile at 200 mph with stock Goodyears and then drove home 400 miles on the same tires with no problems. I also ran Hoosier A6's on the rear and the stock Goodyears on the front when I made several passes in the 217 to 223 mph range. I don't think any of you need worry too much about your tires coming apart as long as you bump your pressure up to 40 lbs or so and make sure you don't have any screws sticking out of them before your runs.

Don't forget to let the air out before you make that long drive back to Austin.:wink

The GT owner's guide says tires should be replaced after 6 years.
