Would you trust 13 year old tires?

Change them as soon as possible. I was in the same boat, and just last week had to put two new B/F Goodrich rear tires on. I went to a show, and on the way home one of the tires split. They looked great-plenty of tread. Change them. They will blow
 
I have a friend in the tire business that told me if you use nitrogen in your tires it will help with your fuel mileage and it will add life to your tires.

Well, no way he's selling anything, right?

I was waiting for someone to say that! It is being used by car companies today to help them reach the goal of mileage set by the government.

Right, so is hybrid/electric vehicles. But when you factor in production/transportation costs, it's a joke. Never use anything the government does as justification for anything. That's a big BIG swirly down the financial waste toilet.
 
A company wouldn't use it if there was no benefit, but being skeptical is normal.
... magazines and TV shows are the ones i'd be wary of
 
I sold a set of 4 Pirelli P Zero take offs off my bosses '88 Lambo 25 anniversary model (only other OEM for this tire size was '88 Porsche 911 turbo) and they sold for over $800 bucks on Ebay!!! I about **** my pants during the last minute when they went from $102 to $812 between 3 bidders. They were dry stored since they were replaced with about 200 miles on them, there was still nubs on the outer edges. My boss was going to dump them as they were too old to run (looked fine to me, not even cracks on the sidewall) but I saw value in them as 100 point restoration trailer queen or Museum piece tires so I told him I would "dump them" for him...:) Seems that tire has been out of print for some time and there was one new set left in the USA when I sold them according to Pirelli's web site search. I was poor in high school and ran used tires all the time, I never had a blow out but once on the rear of my 57 Fordor. That was a 2 year old tire too! The suspension was so soft on that heavy car that I didnt even realize I was flat until the back end got a little squirrely on a freeway lane change. I did have one just let go when I was pumping some gas, just a Psssss, then it was flat. Wasnt the tire, it was the stem! it just cracked and blew off.
 
I don't know if this an apples vs oranges thing.

When I had my sportbike, I changed my tires (both front and rear) every winter. My bike was my only form of transportation, with a daily commute of 35 miles each way, plus my weekend beating on it out on the coast, or in the hills. Also long distance rides up to Tahoe a couple times a year. I used softer (not the softest) compound tires, and always paid attention to tire pressures. I could have gotten away with stretching the tires to last two years, but spending the money (about $300-$400) was CHEAP compared to death or injury.

My bike was a 435 pound missile plus my 175 pounds of blood and bone. How much energy could that deliver at speed? What does your car weigh?

Finally, it's not just your tires, but your entire suspension package. Keep that all in good shape because even if you don't give a **** about yourself, people are driving around out there with their families. If some cheap son of a ***** puts my son's life at risk, there will be more than hot words.
 
It has always amazed me how much time and money people put into their cars, but the only thing connecting their pride and joy ( some would also say bank account ) to the road is 4 very small contact point called tires. if you actually measure the patch of tire that actually touches the road and figure in the horsepower, turning g's and braking acting on it as you drive hopefully the light will come on that they are actually the most important thing on your car.
 
For those who don't know, there is a 4 digit number stamped into the sidewall where the DOT information is. First 2 digits are the week and the last 2 are the year. Just bought a set with 1815 stamped on them - May 2015. I have heard that shops are not supposed to work on any tire 10 years and older.

i have not been able to find a shop willing to balance my N50s because of that

Correct on all accounts. The manufacturer recommendations are a little different by brand, but 10 years is the oldest that are supposed to be run and reputable shops won't typically do any repairs on tires that are 10 or more years old.

Also, the date stamping thing has been around for more than 10 years now, so, if a tire doesn't have a date code they won't service them either.
 
I drove a set of 4 tires on my 'Cuda over 25 years and sold them with the 14" Ralley wheels they were on with about half the tread still on them. No cracks. Garage kept car with very few annual miles. Tried to never get caught in the rain and it rains often in Seattle. ;-)
They were Riken Radials. Tires were put on the car in 1987 or 88.
This is right before putting on the 17" Year One Rallye Wheels in January 2014
Those poor little tires didn't stand a chance against the new 418...

Actually, DOT dating has been around since before 2000. Thou it wasn't industry wide when first implemented. Dot will till you 10 years is the max any shop is allowed to touch. Before 2000 it was a 3 digit code. IE 498 was April 1998. This is great info for us now days. When you go look at a set of tires and wheels at a swap meet, it is nice to be armed with this knowledge.
 
We have to toss any tire at the dealership 6 yrs. or older & write 'em off, by law.
