I have the Maxxis 8008, ST 235/80/R-16 and it appeared that I had a belt separation and ended up changing out the tire last Thursday, the tires are three years old, I don't know exactly how many miles I have on the them; I am outside of Cleveland and I have been to Colorado twice, Tennessee two times, and PA, WV, hand full of times.
So on Saturday I went to my local tire store where I purchased them from and they looked the defective tire, as it did have a belt separation and they told me that Maaxis warranties there tires for 6 years and gave me a $90.00 credit on the damage tire. I went ahead and purchased two new Maxxis tires. So that my experience with Maxxis tires.
