So I have this neat 31 Chevy all steel original bodied car. Has a 241 baby hemi with a late model 4 speed auto. hand built Headers, Holley FI, pumpkin style diff, 4 wheel discs. Super cool car and a blast to drive. Time for tires and I have been put through the ringer the last couple of weeks. So it has early to mid 40s style artillery wheels powdercoated red and vintage hub caps from that era. Front tires are 5.50/16s and rears are 7.00/16s. Very specific tire that only Coker tire makes. They are called the Coker classics.  So I get a first set from Coker and the date codes on the fronts are 1.5 years old but the rears are 4.5 years old. Yes new tires sitting that long. Discount says replace tires at 6 years but in AZ I replace everything at 5 years. (Trailer tires at 4 years.) Typically new tires have date codes from 6-10 months old by the time you get them.  So then I thought I will put some Torque thrusts on there. Not only are they 15s but they are to wide and the offset won't work. So I am really stuck. Both sets of new rears are very soft. These things have probably been sitting in a warehouse in Tennessee the whole time. After the second set the guy at Coker was supposed to talk to his warehouse to look at date codes. Was not holding my breath. Called him back today 10 days later and did not even remember me. Then says he is waiting for the warehouse to call him. How about some initiative to make a customer happy. Told him send me fed ex labels to return all of it and I am just disgusted.   Any way I can't really find a different wheel with the correct offset that will fit on this car. And I really do like the wheels and tires. They are not cheap at $1500 for the set of tires. So do I just run these things for around 4 years which would be 8 years old? New fronts certainly are fresher at 1.5 years old. What say you.

Sounds like you don't have much choice, i they can't get you tires rhat are not dated out of service...  

 
LT215/85R16 is close to your rear size.  I know a really knowledgeable tire guy that could probably help you find something that would work.

 
Just measured and actual tread width is 5.75. That tire is 8.25. Just too wide and fat. My guy at discount already spent a bunch of time trying to find tires to fit other than coker. 

 
I've had tire wholesalers tell me more than once that tires have a shelf life of 3 years and a useful life of 3-5 years after that 

 
I wouldn't trust any tire after 7 years, inside or out.

But, I don't think I'd have a problem running these until then.

Right now date codes on the rears are 2005 and fronts are 2009. I have been driving it up to 50 mph on side streets. Tires still look good. Called Speedway and they got tires from Coker in September. I could order a set from them and return if they are the same old date codes. They probably are. What a fiasco. Also been on the phone with Coker and a different rep to try get the guys in the warehouse to look at their inventory.

Isn't it illegal to sell DOT tires that old, or at least open yourself up for some sort of liability?

Yeesh, sorry man.

 
Well this guy Matt at Coker has jumped on this with both feet. Switching to the Excelsiors and he is pretty sure they are all 2022 or 2023 date codes. Alex at Total Auto Pros will mount and balance these. He still uses a hard 5 year rule in AZ.

I drove around Phoenix on 3.5 year old trailer tires going from SD to Sedona...  1 of them made it.  Luckily, I had 2 spares and the 3rd failure was a bubble about to turn into a blowout.  I agree with this rule for AZ. :biggrin:

 
Finally got some tires from Coker tire that have date codes less than a year old. It is the excelsior tires. Car actually sits slightly lower I'm guessing 3/4 of an inch. Both tires are a little shorter. I'm liking it. Time for a long cruise. Perfect day.
