This is what happens when you drive on tires that are more than six years old. Even tires stored in an air-conditioned warehouse should not be used if they are older than six years. You can see the DOT code on the side of most tires telling you when the tire was made:
Also, in spite of what us old mechanics did for years, ALWAYS put the new tires on the rear if you’re only replacing 2 tires. If you doubt that, check with ANY tire manufacturer. It doesn’t matter whether you’re driving on wet or dry roads or whether the vehicle is front wheel drive or rear wheel drive.
Be prepared to have old -timers argue with you about this.
