Thanks, AMD, this is very important and one of the causes of bad accidents, tread separation. It is often caused by many factors, not just age. I often found relatively new tires <5 years old but start having cracks meanwhile others are still fine even after 12 years old because it was kept in the garage. There are no rules about the age of tires because it has many factors to determine good or bad.

Michelin, Goodyear, Continental, and Bridgestone are actually really good tires. It really depends on how and where the cars were driven. I had 10 years old continental tires and have virtually no crack but the cheap Primewell tires starts to have crack after 3 years because it is parked outside, not in the garage.

@loden888 what Michelin has a cracking issue? I need to note it as Michelin is the most expensive. I like Goodyear because of its cheaper price but performs well. Especially their summer tires.

@ColoradoBoo RV tires are not allowed to be used after 6 years old. That's actually pretty general law in most countries (western). By law, many trailers and RVs max 6 years old to be legally driven on the road. But I think only for trailers that are allowed at max 60mph. But I personally does not agree about that because some tires can be still good if it was not under the sun for many years.

@rryz19 No, there is no such things except for Trailer or commercial vehicle like Buses. Even in Germany, where you cannot wash you car in your parking lot or polish your headlight does not have such regulations. Germany only has regulations for max 6 y old tires for Trailer, not passenger cars. TÜV safety inspection does not fail you too just because the tires are old. But will fail you from burned light bulbs or leaking struts.

@boobtubeakatv1296 It is true, there is no such regulation because tires are rubber and are affected by the environment much more than just age.

@jamram9924 No, there is no requirement to fail or release the vehicle just because the tires are old. You can mention to the customer that the tires are old but garage has no right to fail your car from safety inspection just because tires are old.

@jamram9924 That's true but if the car is always parked in the garage, 12 y old tires may be better than the one with 5y old tires but parked outside.

@jamram9924 yes, I agree. It really depends on the owner and how the car is kept (garage or not). Tread separation sometimes is just manufacturing defects even on new tires. Rubber condition is not easy to judge just by age alone, especially Radial tires. Trailer tires are different, not radial and must be replaced after 6 years and often it is parked on the same spot.
