Hi there,
If tires still are visually in very good condition, threads, side wall, etc. would you replace them with new. They are already 10 years old. The car has been mostly kept in garage.
Thanks for any insights.

 

If it was my car I would replace them. Do you accept the consequences of a flat tire while on the road?

 

Personally I don't keep tires past six years. Tires can last anywhere from six to ten years if they were stored and cared for properly. Ten years is pretty much the universally understood maximum age of a tire. Some automakers suggest to replace them as soon as they turn six years, because you really can't guarantee that they were stored in favorable conditions that would allow them to continue to be safe past six years. The compound gets hard and starts developing micro cracks that you might not see and you could have tire failure in an emergency.

 

I got into an accident primarily because of 8 year old tires. Replace them.

 

I bought my ML in January and it has two sets of wheels: Summer and winter. They're both original, and 10 years old. Both have decent tread (1/4" plus) and even wear. The summer tires feel terrible so I've been driving the winter set. Today I noticed one of the tires was a bit low. I'm getting a fresh set of tires tomorrow.
