Tire age to replace

Hello, when is a good time to replace tires because of age? Manufactures say 6-10 year age range if in perfect condition.

 

When they’re cracking or worn.

 

I should put mine my Tacoma is a 2011 with 30,000 miles garage kept. Original Tires have a 2010 date. Looks new.

 

Like every part if your truck, a regular visual inspection of your tires is important. If they hold air, they aren't cracking, and the tread is wearing evenly (rotate at every oil change). You should be good to go.

Tires do need to roll with weight on them to keep the rubber "healthy" and prevent dry rot.

 

That's a tough one. Tire do age, the chemical bonds break down and eventually layers separate. But for that to happen you need exposure to warm temps, UV, ozone, etc. Manufacturers assume a service life based on putting a tire on a vehicle and using it. IOW, in some time, say 6 years, you're expected to have worn tires down. As a result the amount of antioxidants and anti-hardening agents they put in the compound don't work forever. So you're probably on the 10 year side of the curve because you're not routinely exposing them to a lot of heat and sun.

 

Regardless of how they look I would replace tires after 6 years. Sooner if they look bad.

I'm more concerned about one blowing randomly on the highway or while driving to a hunting spot.

 

Every 7 years to be safe especially if you live in areas of extreme weather like 100+ degrees or -10 degrees during the year.
