My new Early Bird Magazine had an article recomending replacing any tire after 6 years for fear they will fall apart. I put a new set of Black Diamond wide white radials on my T Bird when I put it back on the road several years ago. Won't have 5,000 miles on them in 6 years. Love them but they are expensive. Whats the consensus here on automatic 6 year replacement of tires? The repo bias ply tires I replaced were probably 20 years old or older and never had a failure. Not saying that I probably should have replaced them sooner though. It was apart for restoration for a few years. Thoughts?
The set of five beautiful looking Michelin radials that came on my '55 Bird had 90+ percent of their tread left at 23 yrs old. The spare had never been on the ground.
But the rubber was too hard and they didn't grip the pavement well. On dry pavement they squealed when turning over crosswalk paint at low speeds. They were noticeably slippery after driving thru even small water puddles. The only one I saved was the spare, as a worst case back-up & needing a second spare.
Tires degrade and do have a limited lifespan. A whole laundry list of things will reduce the life expectancy of tires. Different brands and types of tires under different conditions will of course be affected differently.
The '6 year rule' isn't a bad rule of thumb, but it's also a one-size-fits-all creation of corporate liability attorneys.
Being aware of the actual condition of your tires and comparing that to what you need them to do is ultimately up to a well informed owner.
I drove around on the 23 yr old tires for 2 summers, but never went over 50 mph or out of town.
If that's all I wanted from the tires they could still be on the car. If they were the pricey wide whites on a fully restored car I might have bought a second set of wheels & tires for casual use and kept the www's for show days. IF I drove it around between judged car shows.
Personally this '55 is a project/driver and I'm too cheap to buy the wide whites and bought a set of regular whitewalls. If they start falling apart in 6 to 8 yrs I won't feel bad about their low cost. The next owner can put on whatever they like. If I still have it by then I may go resto-mod.
There may not be a 'consensus' here. It really depends on how you use or show your car and your personal expectations.
