tire age a concern?

Great tires from Firestone at a very reasonable cost
I just mounted a set of Firestone Firehawk Indy 500 225/50R16 tires (~$92 each at Tire Rack) to replace my ~10-year-old Firehawk Wide Oval Indy 500's.
These newly released tires are asymmetrical vs the old ones that were directional. Asymmetric tires, IMO, have a significant performance advantage over directional since they can be tailored to accept large cornering forces w/o compromising aquaplaning resistance or braking performance.

I had some perreli 285's - about 10 years old.
Where shithouse, down the drags they would start to light up in 4th, scary as ****. Just to bloody hard.
I got one of those testers and was about 90 from memory, did wheel repare kit for slicks (to try and soften them up) did nothing.
bin job.

Most tires are rated for 10 years. There should be a date stamped on the sidewall unless the tire is very old. Multiple heat cycles and UV damage can weaken the tires, even if the damage is not visible to the eye. The result is less traction and a greater chance of failure. I would replace it. Tires are not a place you want to chance it.
Although a set of tires MAY still be usable, I just don't trust them after 10 years, even though my FD spends 99% of its time in the dry, heated garage.

I've been riding motorcycles for about 6 years now, that experience taught me to be VERY aware of the tires age!! You definitely can notice a difference in grip once the tires hit a few years old. On two wheels, three years is about the max I'll let my rubber age before I get new tires. Granted, you can probably stretch tire use much further on a car, but even so... Performance tires stop performing at the 3-5 year mark.

Although it is necessary to be aware of the potential of tire aging causing a failure, the NHTSA article confirms the fact that tire failures caused by long-term aging are much more prevalent in hotter climates that accelerate the chemical source of tire degradation.
In NE Ohio, 10 years is probably a reasonable assumption for a tire's life, assuming it's not worn out.
In Texas or other hot areas, 5 years is obviously a more prudent time to replace them.
YMMV

Many years back a pretty well-known dude on this forum crashed/totalled his CYM due to being caught in the rain on older low-tread tires. He survived the wreck but was banged up from the airbag deployment, definitely not a good day for him. That always stuck with me........

I never let any of our street tires get below 4/32's (NHTSA says 2/32" is worn out) for just that reason.

It's not even tire failure, but a lack of grip. The first time I drove my MR2 turbo on the track, I was using OLD tires (with tread) and it was like driving on ice.

So if you're feeling it, as you said, it's time to get new tires.

After running 20's for 2 years, I am over 'looking good' but sacrificing ride quality and handling.
I just got some enkei rpf01 lightweight 18" rims. They aren't the best looking wheel, but the performance should be better. Running NT01 Nitto semi slick's.
With this suspension the car should go a lot better
My only experience with really old rubber is through trucks at work that were on factory rubber. The trucks were 6 years old, so I imagine the rubber was of a similar vintage. Anyway one by one they would de-laminate which caused damage and was dangerous if travelling at speed.
I always want newly manufactured rubber when buying car tyres for that reason.
