I posted this on the main board but thought I would share here in case someone doesn't look there often. I know that this is discussed from time to time. Tires that still look new and show no signs of cracking, etc., but are 10/15 years old. Yes I have tires of this description on my F100 and I wrestle with replacing them because they still appear as new. Here is the result of a friends 15 year old tire after a few highway miles. He was lucky to not suffer any damage to his hot rod. Time to get new tires on my F100.
That is an early sign of belt separation when you see outside edge wear and you know the car's alignment is good. Saw it a lot when I did warranty inspections for Uniroyal.
that makes sense I saw that during the firestone debacle I think 721 tire name or some such age was not a big factor as I remember
I've had tires separate like that and were not very old. I had an early '80s Buick Century that all four General tires separated on it. You can hear them go "plop-plop" when you p*** something that will throw the sound back. I won't buy a General tire today because of that experience.
A lot of times we found tires when they were new were perfectly balanced but still vibrated under load,all the tire companies have had this issue from time to time. If the rubber is below temperature when it is in the curing molds it can form an air pocket and in today's m*** production world usually the defect is produced by the thousands tire shops would get updates on the batch numbers to be aware of and return them.
I had a set of new Firestones back in 1967. The tread separated. It bumped & wiggled really bad. I found out after getting replacements, that the most likely issue was that some one in the plant spit on the floor and the carc*** picked that up before having the tread attached. Made sense then.
I think something changed in the manufacturing processes in the last 20 years. I literally had 40 year old tires on my trailer back in 1990. They looked awful and were cracked. I drug that trailer all over the country. I finally lost one when the center of the wheel broke and the wheel departed the trailer at 70 mph. The tire was still in tact. I know, it was dangerous, but poor people have poor ways......
You can Google tire recalls and find out which brands are affected recently,a lot of folks think that newer is better,well not so much https://abcnews.go.com/US/story?id=96216&page=1 Another thing is our old enemy "offshore production" rears it's ugly head when it comes to tires,sadly due to EPA regulation very few tires are now U.S.A. made. Ohio was once the largest producer of tires sadly those factories and jobs are gone and poverty took their place.
