Slight surface cracking can be just cosmetic but keep in mind deep cuts or fissures from excessive deflection, poor maintenance, or defects can be serious so check with a tire shop if you are unsure. You could deflate them slightly or pay to have nitrogen in them. Like most materials - both organic and inorganic- it shows this degradation in the form of cracks. Stuart Tyson My father is notoriously frugal, and I tell him he should replace his old dry-rotted tires even though they still have plenty of tread. Rear tires still appear as new.
Avoid storing the vehicle outside in extreme weather conditions. Fun fact, tire cracks are roughly orthogonal to the strain axis, so examining the cracks can give you an idea of how forces in the tire work and also which are most problematic. Tire cracking, also called weather cracking, occurs on all tires. However if they sit there for long periods the oxides become trapped in the sidewall and begin to damage it. You dont know how deep the crack is or its size below the surface. I would suggest that you consider putting the tires in storage and coating them with a good ozone inhibitor.

The car doesn't get driven all that much -- but it does get driven every week. I'm not recommending this, but I've done it for long term use with no problems. Skidding around corners raises the temperature of a tire, aggravating current cracks and egging on new ones. I won't be buying Michelins again unless it's for a vehicle that runs very high annual mileage.
