Good tires for the money

I bought the tires about 3 yrs ago and have close to 50,000 miles. For the first 30,000 miles they were great ,a little noise. After 30,000 miles they began to make a lot of noise. That has only increased, now to point it has become a problem and I will be replacing them. They are now at the wear bar. Noise is the only problem, when you have to adjust the volume on the radio every time you stop and go it's time to replace. All other performance has been good and they have stayed balance. For the price, a good tire. Tire were mounted on Ram 1500 4x4.
