Technical Bias Ply Age

I did a search, no recent info. Do modern bias ply tires "age out" like radials? Radial tires, if they are 5-6 years old I look to replace them no matter how they look on the outside.

 

Most tire stores will not repair or service a tire that is more than 10 years old, regardless of design. Determining if a tire is safe or not depend on many factors.

 

The steel belts in radials seem to be the problem...since older bias ply tires don't have them, they don't have that problem.

they have other problems

 

Any day driven on an aged or incorrect tire can be the day that life takes a new course.
Think about it. I can say honestly, I do, most days.

 

They age and get hard and many of us drive around on em a lot.

 

I’ve never understood driving on questionable tires. Sure they’re expensive $600 - $2000 if you have a tire come apart and only have it beat up a quarter panel, no wreck or worse you probably just cost yourself a set of tires or more. I’m not sure how long bias ply tires last I believe longer than radials for sure. If they’re cracked, checked or hard I would change em for sure. I guess I’m lucky, never had a set last more than about five years.
