Michelin tires on my 7 year old Toyota corolla show some dry cracks. How much longer can I drive?

On a recent inspection at a Toyota dealership, they told me that all my tires have cracks on them and its not safe to drive them anymore. They also showed me visible cracks near where the rubber meets the road. Now, I have driven my Corolla for a relatively short distance over the last 4 years. (I had bought it used with 12,000 miles on it and current mileage is 50,000). I am usually careful about my driving habits and wonder how much longer I can drive with those tires on without any major safety hazard. Any insights will be very helpful. Also, are there differences in quality of tires based on their brands? The dealership was trying to sell me Yokohama tires (apparently the best) for $55 each and installation charges extra.

Some recommend after 6 years, others after 10 while others have no recommendation at all. Shallow cracking in your tires is normal age-related wear and tear and does not effect the performance of the tire. Deep cracking can be a problem. Your tires are the #1 piece of safety equipment on the vehicle. If its bad they should be replaced.Michelin tires on my 7 year old Toyota corolla show some dry cracks.

If the dealer suggested that you replace your tires it's most llikely that they are pretty much junk.

there are alot of differences in quality of tires based on brands but you also have to look what model of tire they are trying to sell you. search around and go to different tire shops and see who will give you the best deal and the best warranties.

It could be a major safety hazard. I'd suggest replacing tires ASAP. Don't have to buy the best or anything. $29/tire radials should do nicely.
