All tires develop tread or sidewall cracks over time – Just like humans, it’s usually a sign of aging.
Most drivers will wear out the tread before tire cracking ever becomes an issue. But just like tire blooming, tire cracking is common on vehicles that don’t get driven much – Trailers, RV’s, and classic and collector cars, your grandma’s car or church’s van. On these vehicles, it’s possible the tires need to be replaced before they’re worn out.
Just like a 65-year-old person, your tires may look good and be holding air just fine, but put them under load on a 105-degree day and you’re inviting trouble. Most tire manufacturers recommend replacing tires every 6 years whether they’re worn out or not.

Tire cracking is also known as “dry-rot” and happens when the rubber starts to break down due to ozone. UV, and road salt. You can reduce sidewall cracking by using a protectant with anti-ozinant, sunscreen, and a conditioner. I recommend staying away from silicone or petroleum based tire cleaners that work too good and will deplete the tire’s protection and warranty even more.
Tire cracking can also be a manufacturing defect. We use Michelin’s guidelines to determine if your tire cracking is cosmetic (non-warrantable), or severe (warrantable), and will go to bat for you with tire cracking, or any other manufacturing defect when needed.
If you are unsure of your tires, it’s best to get them checked out asap. Call us (508) 443-1845, we’re always here to help.
