My 2010 Civic LX 4-dr. with 25,xxx miles still has the original Goodyear tires with around 8/32" of tread wear left on the tires. It's housed day and night in a garage. The Honda technicians checked off "Satisfactory" (the green square) on my inspection checklist during my last maintenance in June of this year.

I think the manual says to replace the tires after ten years of service -- regardless of their condition. Do forum members here agree with this?

Thanks in advance!

 

Once you see signs of dry rotting or cracking, replace them. When UV exposure is kept to a minimum, like storing the car in a garage, the rubber will last much longer than those that are fully exposed. Ten years is a suggestion by the manufacturer to limit their liability AND push you to replace a set of tires and spend $$$ even though it isn't absolutely necessary at the time. Use your best judgement after a full and thorough inspection of the tires.

 

I replace tires at 5 years no exceptions. Rubber ages when exposed to oxygen and moisture and UV. Plus heat cycling.

 

If you don't have any cracking to the rubber, the rubber isn't in jeopardy of blowing yet and the tires should be okay. If you see cracking, you are in danger of blowing a tire when driving and means the rubber has deteriorated to the point of being a problem.
