There are many people that say one of the reasons that Paul Walker died is because that Carrera GT was still on it's original tires and they were too old and rock hard to handle the cornering speeds they were subjected to that day.
Where are the expiry dates printed on tires? I have never seen them. Where are the safety inspections that take tire age into account? I have never seen them. Where are the cars with 7+ year old tires? On the road everyday, my car included.
Prove it with evidence, not hearsay and tire shop marketing wank. I can understand that performance may degrade, but my old tires are plenty grippy and have not exploded on the highway. I've never seen a tire age test performed, I wonder why that is?
You can bet if it was a real safety issue the tire companies would lobby governments to introduce expiration dates on tires. They can buy the automotive media to spread lies, but they can't lobby governments without actual evidence.....yet.
