Hello everyone,
I have some cracking/dry rot on the outer edge of my tires and in the groves. My tires are rated for 75k miles and that's how many miles I have put on them. I have some tread left in the tire but it's the cracking I am concerned about. Can I get some more miles on them or change them asap? The link provided is a picture of my tires. Thank you!

Thank you guys for your help! Hard to tell how much cracking would create a blowout, so I rather be safe than sorry.
they don't look too bad. tread cracks are minor. Sidewall is still ok. I wouldn't be in a hurry. I would probably use them up, but replace them before winter if you get snow.
Not sure why @yaser got a downvote as his post is 100% true. Obviously someone has never experienced a high speed blowout before.
Looking at the photo, I'd change them immediately. Brakes and tires: two items I do not push my luck with as either can get you killed quick if they go wrong.
I would change it. It is dangerous especially on highway.
I would change it right away. Your life is not worth trying to get more life out of them.
