I bought put 285/70/17 tires on my Ford F150 EXT 4X4 and wished I never bought these tires. I had the sidewall spilt on 2 tires within the first 6 months. They replaced the first one for free and made me pay a pro-rated portion for the second tire. This should of been a free replacement due to a manufactures defect. The tire tread only last around 12,000 miles!!!! Yes, you read that right 12,000 miles! I called their customer service after the second sidewall spilt and they were rude and wouldn't help. They are very loud now and my truck shakes when I go around 70mph. I will go back to ProComp Xtreme MT's.
